I don't think it's an option now and I'd expect that CWL would be very wary of any new airline.
CWL has had unfortunately 4 big hits to it in the loss of Flybe, Thomas Cook, the pandemic and the loss of Wizz. It doesn't help that major routes like Edinburgh and Mallorca have been decimated as well as lost routes not returning.
I tend to agree , I think the last thing CWL needs again is a fresh start airline, WIZZ was a complete disaster whichever way you look at it from a really poor advertising effort after a decent start to the complete and utter lunacy of the cancellations and delays of last year which ultimately killed them off recovering going forward, initial first impressions are vital , I think it’s one of the reasons VY started so well 12 or so years ago where they gave a good overall product with good flight times and also a good price point where unfortunately of late they have significantly stagnated, I actually think this started when a steady enough BCN route was thrown under the bus pre pandemic
I think it’s fairly clear going forward that growth the airport needs can only realistically come from FR, wether that be from a base or W pattern flying I just can’t see who else the airport can have that can offer the critical mass needed
As you say EDI and PMI have been decimated, ORY has been really poor from T3, GLA , JER domestically haven’t returned and also the core sun routes are down on where they were before the pandemic ( WIZZ , TCX effect mainly )
Potential growth from current airlines
LM- EDI 2 x daily , GLA 4 weekly
VY- PMI, BCN returning , increase on AGP, ALC
TUI- potential for 4th based AC
FR- Sun routes
Potential growth from new airlines
SI - JER
LS- Summer seasonal similar to TCX for sun routes
AF- CDG
PC/XC - AYT/DLM
I’d be interested to see where other members see the growth coming from in the foreseeable
