I work at Gatwick (not as a manager) and the only thing left to take away is the onboard product which im sure the company will not do as they would lose too many passenegers.
Gatwick shorthaul barely breaks even at the moment and many routes have been cut for the winter and then some more are being cut at the start of the summer timetable. However the longhaul operation at Gatwick is very profitable with the loads factors being almost 100%, when XL went bust most of the carribbean flying program for the winter sold out.
If any chages are to take place at Gatwick it will be targeted at the shorthaul operation and there has been talk of this going altogether.
