IF something "big" is announced about NYC, I'll go ahead and put my guess in - selling the Shuttle.
- LGA has the perimeter rule (except for Saturday and I don't consider anything that operates one day a week a "big" announcement). US might could get an exemption for PHX since it's a hub, but anything else would be basically east coast only.
- JFK already has B6 and DL hubs plus the widebody rush in the afternoon and early evening. The last think US needs is a "broad in scale" operation at an airport that makes PHL look like the on-time machine.
- That leaves EWR, competing with the CO hub. Anything US could do there would pale in comparison to CO's hub and just add to the delays. How "broad scale" an operation could there be at EWR with 3 or 4 gates?
- Nor do I consider one or two flights a day - to S America for example - as a "big" announcement that's "broad in scale".
For any of them anything that involved more than 2-3 airplanes would take from somewhere - that's PHL, CLT, PHX, and to a lesser degree LAS, DCA, BOS.
On the other hand, selling the Shuttle adds liquidity - not an unimportant factor in this environment.
Of course, this is all my speculation - I'll believe something "broad in scale" will happen when it happens.
