Yeah, there's not really much choice there.
TUI has three 738s based there each summer with a small winter operation.
Flybe is closing their base at the end of the season and will operate solely out of base and with W patterns.
Eastern has a base flying the J41 to Anglesey under a franchise with flybe.
There's a charter company called Dragon Fly with a small operation too.
That's about it.
I think Jet2 is pretty unlikely at the moment. The best chance of a big base is if APD is devolved to Wales and then the Assembly cuts it. That might attract Ryanair over the bridge. Seems unlikely too though.
