At the moment it will be pretty close and extremely busy especially first thing in the morning, This may have further problems in June if the proposed happens. Also with Flybe possibly making an announcement regarding the Frankfurt, Dusseldorf and Brussels with an announcement expected in June, this may further stretch resources depending on the Departure times.
Another problem is whether or not the belt system can cope, it failed on numerouse occasions last year and may cause delays along with Central search this year.
Flybe are to introduce self check-in desks at CWL which would possibly mean that they will require less check-in desks, but as of yet not usre when these are to arrive. I would have assumed they would be installed, trialled and tested ready for the 30th of April.
Thursday mornings will be a true test with the A330 to SFB thrown in for good measure.
