Boeing Dropped Its List of Customer Codes

“I n case anyone is wondering why Brian is referring to the aircraft as a 747-451 instead of a 747-400: the aircraft is a 747-400, the “51” refers to the customer it was originally built and delivered to, in this case, Northwest Airlines. Delta inherited the aircraft when merging with NWA in 2009.”

Boeing Dropped Its List of Customer Codes

Phoenix — who is a reader of The Gateposted the comment you just read in response to this article I wrote pertaining to rare photographs of a Boeing 747-451 aircraft positioned immediately next to a McDonnell Douglas DC-9-51 aircraft near the Delta Flight Museum; and I thought that finding the complete list of all five sequences of customer codes used by Boeing would be interesting…

…but according to this article — which for some reason no longer exists at Puget Sound – Boeing Test Flights — and the “tweet” from Chris Edwards shown above, the Boeing Corporation has abandoned the use of the two-digit customer airline code from its 737, 747, 767 and 777 model lines as of September of 2016, which brings the numbering convention designations in alignment with the 737 MAX and 787 model lines, for which the new designations were initially adopted.

The 737 MAX model line will be referred as 737-7, 737-8 and 737-9.

These changes — which have already been implemented on the certificates issued by the Federal Aviation Administration of the United States — became effective with the following model line numbers for each respective Production Line.

  • B737 As of line number 6082 — with one exception as of line number 6020 — forward, this model line is now known as either:
    • 737-800
    • 737-900
    • 737-900ER
  • B747 As of line number 1534 forward, this model line is now known as either:
    • 747-8I for the Intercontinental series; or
    • 747-8F for the Freighter series
  • B767 As of line number 1102 forward, this model line is now known as:
    • 767-300F, as only the Freighter series is currently in production
  • B777 As of line number 1422 forward, this model line is now known as either:
    • 777-300/ER
    • 777-F for the Freighter series

Summary

I first started writing about this months ago and due to a number of factors — including travel, of course — I never got around to finishing this article; so please accept my apologies if this is old news to you.

Although I do have an interest in airplanes, I personally would not classify myself as an “airplane junky”, nerd or geek like Edward Pizzarello of Pizza in Motion — who will be flying as a passenger aboard the new Boeing 737-MAX airplane today prior to its service to the United States — considers himself; but I thought you might be interested in this information…

…and if I missed anything, please feel free to add to it in the Comments section below.

    I hate to see this change. I knew well what a 727-227 was. I record all flights and loved knowing the plane as originally with another carrier. Great article to read. Thanks.
