UNITED STATES DISTRICT COURT

SOUTHERN DISTRICT OF FLORIDA 

CASE NO. 22-CV-23606-WILLIAMS/REID

JULIAN BUONOMO, 

Plaintiff, 

v. 

JETBLUE AIRWAYS CORPORATION, 

 Defendant. 

 / 

ORDER ON DEFENDANT’S DAUBERT MOTION TO STRIKE 

PLAINTIFF’S EXPERT, KATHLEEN LORD-JONES

This cause is before the Court on Defendant JetBlue Airways Corporation’s (“Defendant” 

or “JetBlue”) Daubert1 Motion to Strike Plaintiff’s Expert Kathleen Lord-Jones (“Lord-Jones”)

(the “Motion”). [ECF. No. 49]. This matter was referred to the undersigned pursuant to an Order 

of Referral by the Honorable Kathleen M. Williams. [ECF. No. 5]. The Court has reviewed the 

Motion, the Response [ECF. No. 60] and the Reply [ECF. No. 65], as well as all the documents 

submitted in support of the parties’ filings, the pertinent portions of the record, and all relevant 

authorities. For the reasons addressed below, it is ORDERED that the Motion be DENIED. 

BACKGROUND

This is an action for damages under Article 17 and Article 21 of the Montreal Convention 

for an incident that took place on February 11, 2022 aboard a JetBlue international flight from 

Orlando, Florida to Montego Bay, Jamaica. [See generally ECF No. 8-2]. Plaintiff was seriously 

injured after hot water was spilled on his right arm and flank. [Id. at 3]. He alleges the incident 

1 Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579 (1993). 

Case 1:22-cv-23606-KMW Document 74 Entered on FLSD Docket 12/22/2023 Page 1 of 10

resulted in first and second-degree burns, scarring, and other permanent injuries. [Id.]. Defendant’s 

Motion seeks to exclude the following three opinions of Plaintiff’s expert Lord-Jones: 

1. Flight Attendant Cruz failed to properly secure and lock the lid in the CLOSED 

position on the hot beverage server while it was placed on the beverage cart 

positioned next to Mr. Buonomo’s seat. Alternatively, she failed to place the lid 

on the server at all. This action was not reasonable in light of industry-wide 

safety practices and created a dangerous condition and compromised the health 

and safety of Mr. Buonomo. 

2. JetBlue failed to adopt, implement, and train its flight attendants on Best 

Practices and Adopted Industry Standards regarding the placement of 

unsecured items on top of a beverage cart during a turbulence event. This failure 

created a dangerous condition that deviated from the standard of care and 

jeopardized Mr. Buonomo’s personal safety. 

3. Flight Attendant Cruz failed to follow her First Aid safety procedures regarding 

burn treatment in flight and provided ice to Mr. Buonomo to apply on his burns 

after the hot water spilled on top of him. This failure deviated from the standard 

of care and compromised Mr. Buonomo’s health, wellbeing, and care. 

ECF No. 49 at 1–2. 

LEGAL STANDARD

Federal Rule of Evidence 702 governs the admissibility of expert testimony. Pursuant to 

Rule 702, an expert witness may testify in the form of an opinion if: 

(a) the expert’s scientific, technical, or other specialized knowledge will 

help the trier of fact to understand the evidence or to determine a fact in issue; (b) 

the testimony is based on sufficient facts or data; (c) the testimony is the product of 

reliable principles and methods; and (d) the expert has reliably applied the 

principles and methods to the facts of the case.

Fed. R. Evid. 702. 

The Court serves as a gatekeeper to the admission of scientific and technical expert 

evidence. Quiet Technology DC-8 v. Hurel-Dubois UK Ltd., 326 F.3d 1333, 1340 (11th Cir. 2003) 

(citing Daubert, 509 U.S. at 594–95). The Court’s role is especially significant given that an 

expert’s opinion can be both powerful and quite misleading. United States v. Frazier, 387 F.3d 

Case 1:22-cv-23606-KMW Document 74 Entered on FLSD Docket 12/22/2023 Page 2 of 10
3

1244, 1260 (11th Cir. 2004). Thus, the party offering the expert testimony bears the burden of 

laying the proper foundation, and that party must demonstrate admissibility by a preponderance of 

the evidence. See Rink v. Cheminova, 400 F.3d 1286, 1291-92 (11th Cir. 2005). In determining the 

admissibility of expert testimony, the Court engages in a three-part inquiry to consider whether:

(1) the expert is qualified to testify competently regarding the matters he intends to address; (2) 

the methodology used by the expert in reaching his conclusions is sufficiently reliable as 

determined by the sort of inquiry mandated in Daubert; and (3) the testimony assists the trier of 

fact to understand the evidence or to determine a fact in issue through the application of scientific, 

technical or specialized expertise. City of Tuscaloosa v. Harcros Chemicals, Inc., 158 F.3d 548, 

562 (11th Cir. 1998) (citing Daubert, 509 U.S. at 589). The Eleventh Circuit refers to each of these 

requirements as the “qualifications,” “reliability,” and “helpfulness” prongs. Frazier, 387 F.3d at

1260. While some overlap exists among these requirements, the Court must analyze each one 

individually. Id. 

As to qualifications, an expert may be qualified by knowledge, skill, experience, training, 

or education. Easterwood v. Carnival Corp., No. 19-CV-22932, 2020 WL 6880369, at *2 (S.D. 

Fla. Nov. 23, 2020). An expert is not necessarily unqualified simply because his experience does 

not precisely match the matter at hand. Id. So long as the expert is minimally qualified, objections 

to the level of the expert’s expertise go to credibility and weight of the expert’s testimony, not its 

admissibility. Id.

Next, in determining the reliability of an expert’s methodology, the Court considers: (1) 

whether the expert’s theory can be and has been tested; (2) whether the theory has been subjected 

to peer review and publication; (3) the known or potential rate of error of the particular scientific 

technique; and (4) whether the technique is generally accepted in the scientific community. 

Case 1:22-cv-23606-KMW Document 74 Entered on FLSD Docket 12/22/2023 Page 3 of 10

Frazier, 387 F.3d at 1262. These criteria apply to both scientific opinions and experience-based 

testimony. Frazier, 387 F.3d at 1261–62. (citing Kumho Tire Co. v. Carmichael, 526 U.S. 137, 

152 (1999)). The Court is allowed significant flexibility to consider other factors relevant to 

reliability. Kumho Tire Co., 526 U.S. at 152. 

Finally, on the issue of helpfulness, expert testimony is only admissible if it concerns 

matters that are beyond the understanding of the average lay person and offers something more 

than what lawyers can argue in closing arguments. Webb v. Carnival Corp., 321 F.R.D. 420, 425 

(S.D. Fla. 2017) (Torres, J.) (quoting Frazier, 387 F.3d at 1262–63). While an expert may testify 

regarding his opinions on an ultimate issue of fact, “he may not testify as to his opinions regarding 

ultimate legal conclusions.” Umana–Fowler v. NCL (Bahamas) Ltd., 49 F. Supp. 3d 1120, 1122 

(S.D. Fla. 2014) (quoting United States v. Delatorre, 308 F. App’x. 380, 383 (11th Cir. 2009)). 

“[M]erely telling the jury what result to reach is unhelpful and inappropriate.” Umana–Fowler, 49 

F. Supp. 3d at 1122 (citing Montgomery v. Aetna Cas. & Sur. Co., 898 F.2d 1537, 1541 (11th Cir. 

1990)). 

DISCUSSION

The Court will first address Lord-Jones’s general qualifications and then discuss the 

reliability and helpfulness of the three proffered opinions. 

I. GENERAL QUALIFICATIONS OF LORD-JONES

Plaintiff defines its expert’s qualifications as “impeccable.” [ECF No. 60 at 2]. After 

obtaining her college degree from the University of Colorado, Lord-Jones was trained by 

American Airlines as a flight attendant and worked for the company for 24 years. [Id. at 3; ECF 

No. 49-1 at 2]. She also worked for the Association of Professional Flight Attendants as the 

National Safety Coordinator for 10 years and provided recommendations to the National 

Case 1:22-cv-23606-KMW Document 74 Entered on FLSD Docket 12/22/2023 Page 4 of 10
5

Transportation Safety Board and the Federal Aviation Administration related to formal accident 

investigations. [ECF No. 60 at 3]. The Undersigned agrees with Plaintiff that Lord-Jones is 

sufficiently qualified to provide the three challenged opinions, which consist of an analysis of the 

carafe at issue, flight attendant training policies, and in-flight first aid safety procedures. The 

qualifications prong is not a stringent standard, “and so long as the expert is minimally qualified, 

objections to the level of the expert’s expertise [go] to credibility and weight, not admissibility.” 

Lebron v. Royal Caribbean Cruises, Ltd., 16-24687-CIV, 2018 WL 3583002, at *8 (S.D. Fla. July 

26, 2018) (quoting Vision I Homeowners Ass’n, Inc. v. Aspen Specialty Ins. Co., 674 F. Supp. 2d 

1321, 1325 (S.D. Fla. 2009).

II. FIRST OPINION: FLIGHT ATTENDANT NEIDA CRUZ FAILED TO 

PROPERLY SECURE AND LOCK THE LID OF THE BEVERAGE SERVER

Defendant takes issue with the demonstration conducted by Lord-Jones, which involved 

dropping a hot beverage server to simulate the accident that occurred on February 11, 2022. [ECF 

No. 60 at 9]. In its Response, Plaintiff explains that Lord Jones took several factors into account

when conducting her demonstration, including the height of an average beverage cart, the height 

of the beverage server, and the approximate effect of the turbulence per Flight Attendant Neida 

Cruz’s testimony. [Id.]. Lord-Jones’s demonstration involved dropping the beverage server three 

times in the on/off position and three times in the closed position. [Id.]. She found that the lid came 

off when dropped in the on/off position and stayed put when dropped in the closed position. [Id.]. 

As an initial matter, the Court has already concluded that Lord-Jones is sufficiently 

qualified to conduct the demonstration, as explained in Section I. She need not be experienced in 

product defect testing, as Defendant alludes to, to provide an opinion regarding the effects of 

different levels of turbulence on the hot beverage server. [ECF No. 49 at 3]. Her experience in the 

industry, as well as providing expertise to the National Transportation Safety Board and the 

Case 1:22-cv-23606-KMW Document 74 Entered on FLSD Docket 12/22/2023 Page 5 of 10
6

Federal Aviation Administration, suffices. [ECF No. 49-1 at 2]. Her experience need not “precisely 

match the matter at hand.” Easterwood, 2020 WL 6880369, at *2.

JetBlue then challenges Lord-Jones’s methodology. It describes the experiment as one 

“that looks like it was designed as part of a fourth grade science project.” [ECF No. 49 at 6]. It 

further argues that she has no technical or scientific background in the area, that it would be 

impossible to retest or recreate her experiment, and that there is no way to assess the potential error 

rate of the experiment. [Id.]. JetBlue complains that she “did no recording, took loose and 

imprecise measurements, and wholly failed to recreate the accident as similar as possible given 

that she haphazardly tossed the carafe around her lawn.” [ECF No. 65 at 2]. 

Conversely, Plaintiff argues that Lord-Jones’s opinion is reliable, as it is based on “an 

abundance of evidence in this case that [she] reviewed, cites in her expert report, and relied upon 

in forming this opinion.” [ECF No. 60 at 6]. Plaintiff states that she reviewed the exemplar carafe, 

the photos of the carafe, and the care and handling instructions describing the different positions 

that the carafe top can be in. [Id.]. Indeed, Lord Jones worked with similar hot beverage servers as 

a flight attendant. [Id. at 8]. Her demonstration, Plaintiff argues, confirms what the evidence and 

her experience already established: “that the top of the carafe would have stayed on when it fell 

from the beverage cart if its top had been properly secured.” [Id.].

The Court agrees that Lord-Jones’s methodology is reliable. This is not a case where the 

“experiment strayed too far from the real-world conditions” and “cannot be said to fit the facts of 

this case.” Varner v. Dometic Corp., 2022 WL 2307002, *4 (S.D. Fla. Mar. 25, 2022). In fact, the 

experiment does not involve “hard science.” It involves an “expert[] offering non-scientific, 

experience-based testimony.” Quevedo v. Iberia, Lineas Aereas De Espana, S.A. Operadora

Unipersonal, 17-21168-CV, 2018 WL 4932097, at *3 (S.D. Fla. Oct. 11, 2018). Here, the Court 

Case 1:22-cv-23606-KMW Document 74 Entered on FLSD Docket 12/22/2023 Page 6 of 10
7

considers whether her “preparation is of a kind that others in the field would recognize as 

acceptable.” Kumho Tire Co., 526 U.S. at 151. As has been established, Lord-Jones possesses 

learned practical experience. In fact, Defendant’s expert agrees with Lord-Jones in certain respects. 

[ECF No. 60 at 7]. In her report, Lord-Jones states that the “results are consistent with my 

experience and training with hot beverage servers that I had used in the past and is also consistent 

with the manufacture’s literature and the testimony of JetBlue Corporate Representative Melendez 

that if used properly, the server will not open and the contents within it will remain inside.” [ECF 

No. 49-1 at 7]. In any case, “objections to the inadequacies of a study are more appropriately 

considered an objection going to the weight of the evidence rather than its admissibility.” Archer

Western - De Moya Joint Venture v. Ace American Insurance Co., Case no. 1:22-CV-21160, 2023 

WL 8767434, at *5 (S.D. Fla. Dec. 19, 2023) (quoting Rosenfeld v. Oceania Cruises, Inc., 654 

F.3d 1190, 1193 (11th Cir. 2011)).

As this Circuit has explained, “sometimes the specific Daubert factors will aid in 

determining reliability; sometimes other questions may be more useful.” Frazier, 387 F.3d at 1262. 

That is the case here. Indeed, the testimony goes far beyond what an “average lay person” may 

offer and would certainly aid the trier of fact. Webb, 321 F.R.D. at 425.

III. SECOND OPINION: JETBLUE’S FAILURE TO ADOPT, IMPLEMENT, AND 

TRAIN ITS FLIGHT ATTENDANTS ON BEST PRACTICES AND ADOPTED 

INDUSTRY STANDARDS

JetBlue contends that the second opinion is likewise unreliable. [ECF No. 49 at 7]. It cites 

to Farley v. Oceania Cruises, Inc., 2015 WL 1131015 (S.D. Fla. Mar. 12, 2015), where the expert’s 

testimony was stricken for failing to meet the reliability prong of Daubert. JetBlue takes issue with 

Lord-Jones’s statement regarding best practices of the International Transport Association, stating 

that Cruz complied with JetBlue’s policy, which did not require anything to be placed on the floor. 

Case 1:22-cv-23606-KMW Document 74 Entered on FLSD Docket 12/22/2023 Page 7 of 10
8

[ECF No. 49 at 8]. But, as Plaintiff points out, the expert’s observation is not that Flight Attendant 

Cruz failed to comply with the company’s policies and procedures. Instead, her opinion is that 

JetBlue itself did not have the proper policies in place. [ECF No. 60 at 11]. Indeed, her 

recommendations are based on industry best practices. [Id. at 12]. This testimony would certainly 

be helpful to the fact finder in determining industry policies regarding the placement of unsecured 

items on top of beverage carts during turbulence and is “beyond the understanding of the average 

lay person.” Webb, 321 F.R.D. at 425. 

Further, Farley is distinguishable. The expert there did not inspect the vessel where the 

accident at issue occurred, did not cite to any publications or experiments to support his opinions, 

and did not provide a detailed explanation of how his experience supported his opinions. 2015 WL 

1131015 at *8. Here, the expert cited to both the International Transport Association guidelines 

regarding catering and equipment checks at different levels of turbulence as well as JetBlue’s own 

Flight Attendant Manual. [ECF No. 49-1 at 7–8]. Lord-Jones then applied these guidelines to the 

statements made by Flight Attendant Cruz, concluding that, based on her “knowledge, training, 

and experience, the safest practice is to remove the items, especially the items containing hot 

liquids, from the top of the cart when an aircraft experiences turbulence.” [Id. at 9]. She goes on 

to state that “[b]y moving these items to a safer location and placing them either inside the cart, if 

possible, or onto the aircraft floor, the chances of these items spilling onto and/or striking a 

passenger is either eliminated or decreased.” [Id.]. Failure to take these steps created a “dangerous 

condition” for Buonomo. [Id.]. Lord-Jones’s opinions are not based on, as Defendant argues, 

“trust-me-I’m-a-flight-attendant methodology.” [ECF No. 65 at 3]. 

IV. THIRD OPINION: FLIGHT ATTENDANT CRUZ FAILED TO FOLLOW 

CERTAIN SAFETY PROTOCOLS

Case 1:22-cv-23606-KMW Document 74 Entered on FLSD Docket 12/22/2023 Page 8 of 10
9

Finally, JetBlue argues that its opinion regarding the use of ice on the burns is “totally 

unnecessary and unhelpful for an expert witness.” [ECF No. 49 at 9]. The Undersigned disagrees.

Lord-Jones’s testimony—based on her experience as a flight attendant for over two decades—

certainly sheds light on Flight Attendant Cruz’s alleged failure to rely on her training or consult 

her in-flight manual, which states that flight attendants should not use ice when treating certain 

burns. [ECF No. 60 at 14]. Further, the opinion itself does not need to be “scientific.” [ECF No. 

49 at 9]. As the court in Daubert and Rule 702 state, the application of scientific, technical, or

specialized expertise can be used to aid the trier of fact to understand the evidence and determine 

a fact issue. Daubert, 509 U.S. at 589; Fed. R. Civ. P. 702(a) (emphasis added). The evidence does, 

however, need to be reliable. Thus, “[f]or nonscientific expert testimony, the trial judge must have 

considerable leeway in deciding in a particular case how to go about determining whether 

particular expert testimony is reliable.” Am. Gen. Life Ins. Co. v. Schoenthal Family, LLC, 555 

F.3d 1331, 1338 (11th Cir. 2009) (quoting Kumho Tire Co., 526 U.S. at 152). “A district court 

may decide that nonscientific expert testimony is reliable based ‘upon personal knowledge or 

experience.’” Id. Here, Lord-Jones concludes that the flight attendants were not properly trained

on JetBlue’s Flight Attendant Manual based on their actions following Plaintiff’s burn. [ECF No.

49-1 at 10]. She considers the accident together with the relevant section of the manual that

discusses varying severities of burns and first aid actions that should follow. [Id.]. The testimony

would thus be helpful and meets the Daubert reliability prong.

CONCLUSION

Based on the foregoing, the Court orders that Defendant JetBlue Airways Corporation’s 

Daubert Motion to Strike the Testimony of Kathleen Lord-Jones [ECF. No. 49] be DENIED. 

SIGNED this 22nd day of December, 2023.
