My son is doing a research paper regarding the aviation industry consolidation and a section of his paper specifically details flight number ranges. As we all know, each carrier is limited to 9,999 flight numbers and the specific focus of this subsection is geared towards how merged airlines consolidate their flight numbers as a whole. This includes all mainline, regional partners and codeshare/alliances.
I've been provided information for US, DL and AA but I'm still looking for the United 1-9999 flight number ranges which, due to the recent merger with CO, is going to be a large example within his thesis. Ideally, just so it is an apples-apples comparison, he would want all flight numbers within the 9,999 range just so he can see what is allocated for sale, administration/testing purposes, extra section, repo flights, charters and the like. This would allow him to directly compare across carriers the normal use of numbers and will also allow him to consider how airlines propose to grow in the future.
By the way, when is the industry ever going to allow carriers to have more than 10,000 flight numbers?
