It is a good section of the industry, more individualistic than an airline. Same rules and regs, but beware some of the 'Pikey Operators' though the main 2 in the south are at the exit gate. Location depends where your wife will be located. There are posn's @ LTN, BQH, FAB being advertised. Check Avth Job search for Ops jobs. Think also of the support ops like Jeppesen UK (LGW), Universal (STN) or even AirRouting at (LTN) or the big Brokers like Air Partner, Chapman Freeborn etc. Ctc's via a Google or PM me.
Good luck
