If Flybe had released only their Mediterranean flights yesterday then perhaps I could believe that this was a reaction to Easyjet, but looks like they've put their full schedule on sale for their entire operation. On this basis it'd be almost impossible for this to have been a knee jerk reaction to EZY putting GVASOU on sale.
It's also unlikely they'd suddenly pull the schedule out of the bag at short notice when you consider the size of their operation. There's been a change of management so perhaps that brings with it a change of heart when it comes to these routes. Surely it's good news to have these on sale so early rather than the indecision we've seenin previous seasons!
