 Exemption No. 10064C 

 Regulatory Docket No. FAA-2010-0408 

Mr. Michael Wuerfer 

Director, Flight Safety, Regulatory Compliance, and QA 

Allegiant Air, LLC 

1201 North Town Center Drive 

Las Vegas, NV 89144 

Dear Mr. Wuerfer: 

This letter is to inform you that we have granted your petition to extend Exemption 

No. 10064, as amended. It explains the basis for our decision, describes its effect, and lists 

the conditions and limitations. 

The Basis for Our Decision 

By letter dated March 18, 2016, you petitioned the Federal Aviation Administration (FAA) on 

behalf of Allegiant Air, LLC (Allegiant Air) for an extension of Exemption No. 10064, as 

amended. That exemption from §§ 121.623(a) and (d), 121.643, and 121.645(e) of Title 14, 

Code of Federal Regulations (14 CFR) allows Allegiant Air to conduct supplemental 

operations within the 48 contiguous United States and the District of Columbia using the 

flight regulations for alternate airports as required by § 121.619 and the fuel reserve 

regulations as required by § 121.639 that are applicable to domestic operations. 

In your petition, you indicate that there has been no change in the conditions and reasons 

relative to public interest and safety that were the basis for granting the original exemption. 

The FAA has determined that good cause exists for not publishing a summary of the petition 

in the Federal Register because the requested extension of the exemption would not set a 

precedent, and any delay in acting on this petition would be detrimental to Allegiant Air.

Our Decision 

The FAA has determined that the justification for the issuance of Exemption No. 10064, as 

amended, remains valid with respect to this exemption and is in the public interest. 

Therefore, under the authority provided by 49 U.S.C. §§ 106(f), 40113, and 44701, which the 

FAA Administrator has delegated to me, Allegiant Air, LLC is granted an extension of its 

exemption from 14 CFR §§ 121.623(a) and (d), 121.643, and 121.645(e) that allows 

Allegiant Air to conduct supplemental operations within the 48 contiguous United States and 

the District of Columbia using the flight regulations for alternate airports as required by 

§ 121.619 and the fuel reserve regulations as required by § 121.639 that are applicable to 

domestic operations, subject to the following conditions and limitations.

2. Allegiant Air must ensure that its aircraft dispatchers hold aircraft dispatcher 

 certificates issued under subpart C of part 65 and are properly qualified under 

 part 121, subpart P, before permitting those persons to serve in operations 

 conducted under this exemption. 

3. Allegiant Air must conduct its supplemental operations under this exemption-- 

(a) Within the 48 contiguous United States and the District of Columbia; and
