aex, I am sure the ground staff will be the subject of TUPE if they are to be transferred across to Aria. and i am sure they will apply the same standard of service that they do for Cobalt and the airlines they service, but the Aria management must have promised somethings to BA to get them to swap to them where as if BA had stayed with Cobalt they would have had an almost exclusive service from Cobalt at LCY, your own handling agent but without the overheads of having it in house sounds like the perfect set up.
