Are pilot's still going to be based at either LHR or LGW?
By your question I assume you mean two seperate bases? I assume so, LGW operates different payscales, pay caps and rostering systems on the 737 which I believe will continue when the fleet has transitioned to Airbus. There was initially a dual basing system as the LHR airbus crews would often cover work at Gatwick however, as the Airbus fleet grows at LGW that will decline.
The 777 is a different story as the fleet is 'run' from LHR with LHR flight crew but LGWcabin crew as I don't believe there is enough work, aircraft or F/C willingness to operate LH under Gatwick rules/rostering to justify a Gatwick base per se.
As stated above that is my opinion, I'm sure anyone from the Airbus fleet could possibly correct or corroborate the above.
