Where is that the case? Again, they are *certified* as 777-300ER, that’s indisputable fact. They can be marketed as 777 Friend Ships, LuxuryLiners or Whisperjets, but the customer codes are history for Boeing.

The Boeing customer codes started with 707 orders in the late 50s. The initial model was ther 707-120. The first proposal was to PanAm which wound up as 121. The second proposal was a 122 to United, who went with DC-8s, but the number stayed. And on to 99, then restarted at -101 (Piedmont). When they ran out of available numbers, letters replaced a digit.

The airline that orders a Boeing aircraft have options they make on the airplane...from placement of gauges, up to which way the landing light switches flip up or on or down for on/off. When another airline buys or leases aircraft to use say Delta 757-232 with TWA's 757-231 Delta will provide training on differences so flight crews are aware of which placements and options that airplane has apart from their own model that they are used to. And/or what equipment it does or does not have. Example is the 737MAX as some airlines ordered the angle of attach displayed on the EICAS and others did not, as with the whole MCAS controversy going on right now.


Not anymore on new models. There are far fewer options offered on new Boeing models. You can get stuff like metric units or Integrated Cue Flight Director, but not the stuff you mention. You aren’t going to get different switch placement on a 787.

Also, not only does the 737 not have EICAS, but the optional AOA display is on the Primary Flight Display.

On filings on their website. Talking about future deliveries or current fleet assets they have them listed as “777-322ER”. There is also RobK who had verified Boeing themselves still uses the codes in production of 737NG, 777 and 767.

As many people have stated, it's the customer code. For example, Continental's 737-800's are 737-824's, Southwest's 737's are 737-7H4's and 737-8H4's, Delta's 737's are 737-832's and 932ER's, and so on and so on.

Last two digits on a Boeing model reveal the customer code, for the airline that originally placed the order for that aircraft.
United's is 22, Continental's was 24.

This doesn't apply to MAX, 787s, 777X, and 747-8, as those aircraft have all gone to the (ridiculous) -8/-9/-10/etc numbering system.


I thought the 747-8 was in a bit of a grey area? They got the single digit numbering system but have customer codes?
E.g. CX Cargo 747-867F

If they are, it is because someone made it up.


Boeing no longer uses the codes. But certain types will want to attach they airlines code anyway. Nothing stops some one internally from calling it a 322ER if they want to.

On the flip side, maybe someone could call the 787-924. That is also imaginary but it wont stop people from doing it they want. Doesn’t make any of it real.


You will never see anything public facing using these imaginary codes.

In the past the app may have noted the difference between a 777-222 or a 777-224 but at this point even the REAL codes any no longer displayed (just -200) and certainly not pretend ones.

FWIW, I imagine the old sUA 772 would be the last planes ever delivered with a -22 code from Boeing. CO order aircraft would have continued with the 24 code even after the merger till these were discontinued

Can't believe there is a thread about this! Been explained in countless A-net threads. Simple answer is Boeing used to assign a customer code to each airline that ordered an aircraft. In the early days it may have meant something as far as configuration/options but that is no longer the case. Boeing has since discontinued the customer code on the 737 Max. 747-8, 787 and 777X. As for the United aircraft mentioned in the OP, these were ordered under the old system. So a 777-322ER was initially ordered by United (Boeing customer code 22) and a 737-824 was initially ordered by Continental (Boeing customer code 24).

Since United and Continental merged it is not surprising there are aircraft with both a 22 or 24 in United's Boeing fleet.


Most of the legacy 787-8 and 787-9 were CO orders hence why they kept the -224 Boeing code. 773s were legacy UA order post integration with CO and are -322.

Correct me if I'm wrong but I think all the 737-900ERs are -224 as well.

CO Boeing Customer Code is 24, not -224; so, the CO 737-900ER's would be 737-924ER's (and some 737-900 non-ER's).
And the 787 never had Customer Codes assigned to them; the TCDS does not list them, just 787-8, 787-9 or 787-10.

You can’t help but laugh at how many time the same fact is repeated by various people in assorted ways.

Yet, if some one wants to believe in a 777-322 and 787-924 I suppose no one can stop them!

Ah thanks, brain fart on my part. So there are no 739s with the -22 at this point?

Check for yourself No 737-922's or 737-922ER's were produced.
And again, Boeing Customer Code for United was "22", NOT "-22"... No dash in the Customer Code as the dash was in the Model Designation.

Relax, it's not that important. I meant to say "-22" at the end of the aircraft type.

Aircraft are more modular and standardised these days. Back in the day TWA for example, had its flight deck switches installed to flip in the opposite direction to everybody else. Qantas had a shortened version of the 707-100 to allow for extra range. BA often had non standard galley's installed. Ansett got its first 767s with a flight engineers panel fitted when other carriers went straight to the glass cockpit.

If you look at the Airbus system, which obviously came along much later, and with aircraft far more modular in design, you can see a system
that kind of makes more sense. For example. An A320-214, verse an A320-221. The first 2 obviously designates the body type. The second number
is the engine manufacture. The 3rd number is the engine thrust and MTOW.

I've been on Anet for close to 20 years now, and I never knew - or saw a thread - about the last two digits being the customer code. Maybe everyone complained for the thread to be closed because "THIS HAS ALREADY BEEN COVERED" and the topic disappeared. I am glad I finally learned this today!

Actually Lufthansa as well as every other European airline and several other world wide had the "ON" position aft -- it was the European standard. And although Ansett took their 767's with an FE position they were still "glass" cockpits. IIRC about the strangest thing was an Air France 727 FE panel in French and the Australians had 737's where the overhead panels were all dark grey instead of having the Fuel, Electric, Hydraulic and Air Conditioning panels a lighter grey.

Oh I knew the 767s had CRT displays.... but they weren't properly utilised as they would be today. But yes the point remains things were less common across fleets.
Interesting to know about the switches being a European standard. It kind of makes sense why TWA picked it now. They had quite a few 727s dashing all across
Europe at one point.
