Finally! Only about 10 years late to the party!
I bet we do see it at some point, anyone can see they're going to end up with more than 30 of them, I bet they end up making up about 50% of the fleet. Natural progression to go for the larger aircraft, who knows, EZY might even flirt with the A321LR one day?
As of this minute, our 2 current A319's will evolve into 2, 186 seat A320/A320neo, however I hope that doesn't happen. I'd much rather see them turn into 3/4 Cseries, with an A320neo for the summer beach shuttles. Fingers crossed!
