Trouble with getting A319's is that you can't do any mixed fleet flying.... You would need dedicated crews for A319/20/21. Because according to CAA rules your not allowed to fly A319/20/21 and A330. And considering that MON still has got 2 A330's this wouldn't be the best way about it....
Maybe a less dense configuration... So more legroom seats....
We'll just have to wait and see
Cheers
