So here's a full summary of the changes...haven't seen it posted on here yet:
Permanent cuts: SFO-ABQ/MCI, LAX-PHL, SAN-ABQ/ELP/MCI/MSP/OMA/STL, BOI-RNO, SJC-BUR
Seasonal cuts: SFO-BNA/BWI/PHL/RDU, SAN-BWI
New routes: SFO-ANC/GEG/RDM, LAX-GEG/RDM/BOI/MSO, SAN-RDM
Additional frequencies: SFO-ORD/SNA, SAN-MCO/BOI/BOS/STS/SJC
Thank you for this wonderful summary! None of this comes as a surprise, of course. These changes seem to not only play to AS's strengths but also further indicate a truce between AS and WN. After all, WN recently threw in the towel on routes like SFO-AUS/DAL. They also reduced DAL-PDX/SEA to seasonal service.
Hardly surprising to see AS eliminate the last of its California-ABQ/MCI services, which never made much sense to begin with. ABQ and MCI, like other AS heartland markets, will continue to be served from the far less competitive Pacific Northwest hubs (PDX and SEA). I believe WN may have even reduced or eliminated its own ABQ/MCI-PDX/SEA services recently.
I never understood the expansion from SFO to markets where the AS brand was virtually unknown (i.e. BNA, IND, PHL). Those missions always seemed much better suited to UA, and I'm not surprised to see AS *finally* focused on linking its SFO hub to markets where it is somewhat strong (i.e. ORD, SNA) to very strong (i.e. ANC, GEG).
LAX will be interesting to watch. I figured a number of routes were on the chopping block along with PHL - BOS, BWI, DAL, FLL, IAD, LAS, ORD and SLC spring to mind. Even LAX-PAE seems to be struggling - and that is a niche route shielded from the excessive competition typical of this market. Maybe AS's LAX hub is working now that Hawaii and the East Coast have been added to the longstanding PNW and Mexican Riviera services, but I certainly wouldn't be surprised to see further cuts down the line.
Sad but not surprising to see BUR-SJC go, as the opportunity to add BUR-SFO has probably come and gone what with WN now well established on that route and a resurgent UA rebuilding its presence on that route. Maybe the intra-California trunk routes really are best left to WN?
As far as SAN is concerned, I never understood the rationale behind all the services to flyover country. It seems like AS services to places people actually want to go, like BOS and MCO, have been quite successful. Why not build on that success with services to places like FLL and ORD rather than OMA and STL?
