They have said they have been happy with quiet a few other bases that are now shut even after swapping aircraft types there and training all the crew up to fly the new type sometimes less than a year after they heavily invested in training.
You will just have to wait and see what the financial types decide. punters tend to always favour there local base and think everything is great there, mind you so do the crew. But when it comes down to seat yield and competition the bean counters will win.
I do have empathy for the pax but after having several mates be made redundant by flybe then weeks later be asked to return (which thankfully they refused as they were just so pissed off with them) what ever happens it will cause a great deal of stress to a vast number of family's which won't be affected by if their base closes or not. From the last round of redundancy's I think everyone I know is pretty glad they left. Several operators are now sniffing out the crew both on jet and Q400 and also technicians. It could be they have no option with some bases if they have to many people move on. I have already stuck 3 cv's through of Q400 Captains to other mates who are looking for heavy TP drivers. A reluctance to move the family or go sideways to ATR will be the handbrake for most. Now Ryanair have thrown a carrot out for PIC time quickly on a 737-800 for Q400 PIC then it maybe carrot enough to abandon ship.
This is all speculation on my part.
