Flybe's bucket is far from empty. They come off the back of a profitable past year following significant cost cutting and a successful £150m capital raise.
Sure both routes have been tried before but the schedule is now broadly improved over previous offerings, particularly on LBAABZ. Demand on the route will be stimulated by the significantly lower fares offered by Flybe over Eastern.
Time will indeed tell, but I don't think we'll have to wait too long to see what Eastern do.
