hey
At EasyJet in the UK who i work for at the moment there is a Pre op TS working based in Gatwick, from what I could gather from conversations there have been no problems with Airside ID's etc...
to be honest i shouldn't see why it should be a problem anywhere, all companies bang on about equal rights and equal opportunity employers.
I say good luck to you! and let us all know how things go! just apply apply apply.
