Gate alignment
At PHL, it seems that AA is in A-East but someone on the forum mentioned that AA has plans to move to Terminal D, where there is no US presence, so I think the wise thing to do will be to stay put at A-East.
At CLT, AA is in Concourse A and US has presence in all the rest with B, C and E for their exclusive use and D - dedicated to international flights. Not sure if US will have space in their concourses to move the AA gates out of concourse A. The new AA may have to occupy all concourses at CLT.
At MIA, it appears that US will be moving to concourses D and E where AA is.
At ORD, new AA had to divest 2 gates but they were specified to be AA gates in Terminal 3. I would have preferred to have 2 of the US gates at Terminal 2 divested and the additional US gate moved to Terminal 3 in Concourse L where Spirit/Alaska/JetBlue/Virgin America have gates and can have one or more of them move to Terminal 2. With AA having to divest one of their own gates, that means all 3 US gates from Terminal 2 would have to be swapped with one of the above carriers to make the move to Terminal 3 but US will be moving to Terminal 3 Concourse L.
I'm curious to see what happens at BOS - with so many gates between AA and US, it'd be interesting to see what role BOS will play in new AA's network. With its presence exceeding BOS' "home" airline JetBlue - I wonder what new AA will do with that - maybe offer more international flights?
At DFW, AA is in terminals A,B,C and D and US is in E, unless AA can have the US gates moved to any of the A, B or C terminals (space permitting), US may have to remain at Terminal E as Terminal D is international and no domestic carriers operate out of there, so no gate swap is possible.
At LAS, both AA and US are operating out of the D gates but not sure if they are adjacent to each other - even if no moves are possible, all D gates are easily accessible, so it shouldn't be an issue for connecting passengers (if any).
At EWR, both AA and US operate out of Terminal A and I believe the gates are in the same concourse and adjacent, so not much work required there.
At FLL, both US and AA are in Terminal 3, Concourse E, so not much needed there.
At DEN, US is in Concourse B and AA in Concourse A. AA cannot move to Concourse B as the rest is occupied by United, so US will have to move to Concourse A.
At SEA, US is in Concourse A and AA is in Concourse D. AA used to be in Concourse A but moved to D to make space for United, so now US will have to move to Concourse D.
At MSP, both AA and US are in Concourse E, so even if gates are separated, they are easily accessible.
At SLC, both AA and US are in Concourse A, so shouldn't be any issues there.
At ATL, AA is in Concourse T and US in Concourse D. United is split between both but they have an United Club in D, so maybe US can swap its D gates for United gates at T. AA has an Admirals Club in T, so common sense dictates they'd want to keep it.
At CLE, both AA and US are in Concourse A, so not much work needed there.
At MKE, AA is in Concourse C and US is in Concourse D. The rest of Concourse C is used by WN/FL, so no consolidation can happen there. Either, AA moves its gates to Concourse D where there are a lot of abandoned F9 gates (if possible) or both AA and US can move to Concourse E which is currently only occupied by United & AC.
At BDL, both AA and US gates are adjacent, so nothing needed there.
At BUF, AA can have United take over its gate 11, so that JetBlue can occupy United's Gate 10 and AA can co-locate next to US at JetBlue's Gate 7 next to the US Airways Club as well.
At PIT, US is by itself in Concourse B, while AA is in D. Unless US can accommodate the existing AA flights out of B or the airport decides to open a few more gates in B to have AA move there, AA's gates will probably remain in D, however, it's an easy access between B and D, so there should be no issues.
At SMF, US is in Terminal A and AA in Terminal B. It's possible that either one of them moves to the other terminal. Time will tell what they'll end up choosing.
At RNO, both AA and US are in Concourse C, so even if gates are not adjacent, that shouldn't be a problem.
At ONT, both AA and US operate out of Terminal 4, so no additional effort should be necessary.
At SAN, AA is in Terminal 2 East and US is in Terminal 2 West. Considering AA has an Admiral's Club in 2 East, it would be wise for US to move there.
At SNA, AA is in Terminal A and US in Terminal B. AA has and Admiral's Club there, so my guess is US will be swapping gate/gates with either AS or DL.
At SJC, both AA and US are in Terminal A, so unless gates are not adjacent, no further work should be needed.
At BWI, AA is in Concourse C and US in Concourse D. If Spirit's gate space is enough for US to move into, then AA can consolidate in C, the rest of C is occupied by Southwest/AirTran. Otherwise, if AA can fit into JetBlue's gate space in D, they can move there and consolidate in D. Those are the only 2 options I see.
At SFO, US is in Terminal 1 and AA in Terminal 2. With Terminal 2 being nicer than 1 and having an Admiral's Club, the logical choice would be a move to Terminal 2 if the 14 gates there are sufficient for the joint AA/US and VX operation. Otherwise, a shuffle at Terminal 1 may be possible.
At PBI, AA is in Concourse C and US in Concourse B. US can swap with AC and/or DL and consolidate in C or have AA swap gates with United and consolidate in B.
At TPA, both AA and US are in F, so no consolidation necessary.
At RDU, American is in Concourse C and US in Concourse D. Their gates are at opposite ends of each other. Thus, the best solution is for AA to swap gates with UA and AC and have the entire Concourse D to themselves.
At MCI, AA is in Terminal C and US in Terminal A - new AA can consolidate in Terminal C.
