sounds abit crap! What are the LGW crew going to be doing through the summer? is there to be a FJE A/C based at NCL and MAN through the summer? It does seem that they want to push you out before they have to pay you out, realistically why do they want staff based at LGW when there is no base there anymore, does seem a bit pointless, not that its the crews fault!
Best Of Luck, maybe its time to look for a new airline though!
