Although final plans have not been released by the governor's office or the Port Authority, the original plan for the redevelopment was for Terminal 1 to handle the airlines with ownership in the Terminal 1 Consortium plus all other Star Alliance carriers. Terminal 4 would handle Delta with SkyTeam and Delta's partners split between 1 and 4. Terminal 5 and the new expansion would handle B6 and its partners, and Terminal 8 would handle all OneWorld carriers which do not participate in the Terminal 1 Consortium.
I honestly think this scenario can’t come to live soon enough, but T1-2-3 rebuilt will take some time.
It’s true that alliances, partnerships, joint business agreements and cross-ownerships come and go, so planners and builders can’t react in real time, but it’s incredible how tight JFK terminal space is that moves of airlines with just more than 1xdaily flight seem unbearable.
T1 is managed by TOGA (AF KE LH JL) and it is quite maxed out for airlines to be grouped by alliance (being formed by airlines from all 3).
But it’s mind blowing that KLM, part of AFKLM can’t collocate with AF to share staff, facilities and costs in the end.
Same with LH Group, where Swiss is in T4 and EW at T7 instead of being “grouped” along LH, OS and SN.
Also Norwegian operates out of T1 except 1 flight to MAD that goes at T7.
More “weird things” happen at T7 where Qatar operates its evening flight while the morning one goes at T8.
And Aer Lingus purchased some years ago by IAG operates out of T5 instead of sharing facilities with BA and IB.
It just seems way too complicated and as I say above, simplification and rationalization of spaces, can’t come soon enough.
