FCA is TOM
You seem to forget that FCA is TOM.
By next summer they will be operating as Thomson Airways.
long term objective over next 5 -10 years is to have all short range A/C as 737-800 and long range A/C as 787.
This means they will gradually come off their leases for A320, A321, 733, 752 and 763 between now and then.
hence you should all expect to see base changes to the above over time.
I am not sure TCX will be in hurry to up capacity either. They too are on a capacity reduction post their merger with My Travel.
Reductions in current charter capacity around Europe, especially UK are driven off the mergers last year when 4 are now 2.
I think you will see a growth in other small operators again to start to fill the gaps. XL and Jet 2 are trying to push into the holes, but neither will be in a hurry to come to South Wales.
