message: The page mentions a 2 character airline designator suffix after the 4 to 5 digit serial number. However, looking at IATA manuals (i.e. AHM587 Container/Pallet Distribution Message (CPM), and PCM27th edition: .U element description in RCP1745) i conclude that the airline designator can be either 2 or 3 positions.
The maximum length of an ULD identiication can therefore can be 11 characters, instead of the suggested 10.  —Preceding unsigned comment added by 85.147.13.137 (talk) 20:50, 23 October 2008 (UTC)
thread_title:  ULD identification format 

message: I'm concerned about the characterization that ULDs are only used on wide-bodied aircraft as mentioned in the very first line of the article. Of course wide-bodied aircraft predominate the air cargo world, but there are 737 and 757 freighters out there, not to mention surviving DC-8 aircraft. 207.200.116.9 09:41, 8 January 2006 (UTC)

replies: text:  correct on the 320; all original AC A320s (fins 201-249) take ULDS while the ex-Cdn Airlines and Jetz 320s (fins 401-413) are bulk. also, the A321s (fins 451-460) are all containerized. incorrect on the lack of code. every ULD has codes. this one is the "LD3-45" refer to: http://www.aircanada.com/cargo/en/fleet_ulds/ulds/pallettes1.html.

thread_title: Not Copyright Violation

message: Fedex is replaceing their 727's with the 757's and there is no mention of which uld will be used, as 757's will be going into a lot of cargo conversions.
: The FedEx 757s have 15 topside positions with eight (maybe ten?) non-containerized belly bulk positions. One of the tail numbers for one of their aircraft is N901FD; I believe the other might be N918FD. Position 15 requires the use of two Demi (AYY) containers; apparently, it is extremely unwise to place a contour (SAA/SAX w/o DG) in 15. All of the other positions can support either two demi containers or a full contour. In addition, the topside also supports PGP pallets for sure; I'm uncertain about whether or not PMC or PLA pallets are supported topside. An interesting sidenote of information that I've heard from people who've loaded the bulk positions on the 757s is that they're a huge PITA to load. Sarienpalth (talk) 10:33, 22 July 2009 (UTC)

thread_title: What about the 757's?

message: I've a lack of info, or really even any mention, of main deck ULDs. The article seems to deny the existence of any sort of main deck load unit other than pallets. I'm going to look at adding some info but as main deck loading schema tend to vary quite a bit, particularly at the express carriers, it can be a bit hard to find data on some of the more obscure types of cans.

replies: text:  I deal with ULDs on a daily basis. For example, there are actually two different types of AMJs at our workplace: contour- and square-backed. Beats the heck out of me as to why, but it might have something to do with which planes the containers were originally designed for. It looks like the list is pretty accurate. There are a couple of highly-specialized ballast pallets that might be added if they're not on there already (I'm referring to the PAH, et al) and one Truck Only container that I've come into contact with.

thread_title:  Update 

message: This is a list of question, comments, ideas. Help me out; or add your own questions and ideas.
*I know IATA uses the 3-letter prefix for identifying ULD types. But who designates the LD-number? (LD1, LD2... etc) Is it designated by the manufacturers?
*Can someone verify the proper usage of the name "LD7"? It seems like people who work with the equipment use loosely it to refer to any 10-foot pallet (125-incher). I would like to see a citation of some sort, because I'm starting to think it really refers to one specific pallet.
*To hyphen or not to hyphen? (LD3 vs LD-3)
: I don't think it matters; I don't usually refer to containers by their LD(k) notation. I usually just use the tripartite preamble when I'm at work. Sarienpalth (talk) 10:39, 22 July 2009 (UTC)
replies: text: I know I've personally worked with a few of the containers listed here myself. I might see if I can take a tape measure in to work and take some container measurements for rough orthgraphic diagrams. If anyone can suggest a decent open-source CAD/CAM program, I'd be willing to build the orthographic drawings using that software. Sarienpalth (talk) 10:39, 22 July 2009 (UTC)

text: Directly on a truck or ship, as is? No. ULDs can be loaded into a trailer (container in another container). It's not unusual for a trucker to pickup a loaded ULD, have their own warehouse people unload it, then truck the empty ULDs back to the airline. Though, most of the time it is unloaded at the airline's warehouse and the trucker picks up their cargo on a skid. In theory, a ULD should fit in a ship's container, but that isn't done. Airlines are very possessive of their ULDs and want them back in the system as soon as possible; so loading them on a ship going to who-knows-where is a no-go.

thread_title:  Improvements to the Article 

message: I'm not an expert in cargo containers but I write a lot about airplanes. And in the "cargo capacity" section of A320 I keep seeing LD3-46 designation. Does it mean that (a) the height of the container is 46 inches (and not 45 as the article states) and (b) that this is an official designation for this type of containers? I'd be thankful if anyone could comment on this. BadaBoom (talk) 22:58, 30 October 2012 (UTC)

thread_title:  History 

message: There ought to be a section describing how haulage companies make use of ULDs.   Ie are they rented from the airline?  Given that many companies will ship only one way, is there one way rental?   Are ULDs transported to the sending depot to be packed there, then transported by truck to the airport, then flown, then transported by truck from the destination airport to the final depot for unloading before being returned to the owner at the destination airport?   Or are they packed and unpacked by airline staff at the airport?   If the latter, how do shippers ensure that they maximise the space utilisation in a ULD?
FreeFlow99 (talk) 11:35, 20 March 2015 (UTC)
replies: text: It depends on the contract. Most of the time airline contractors load and unload ULDs on site at the airline's warehouse. But occasionally the shipper will borrow ULDs and load it themselves in their own warehouse. I don't know if they pay an additional cost to do that. It's usually shippers that are moving large amounts of fresh produce that prefer loading ULDs themselves. Jigen III (talk) 11:32, 22 July 2015 (UTC)
