I do hope for your sake that this all comes to fruition as you definitely seemed a bit obsessed over the thought of Cobalt flying from Cardiff.
There are alternative airports that you can fly to Cyprus so don't I wouldn't hold back that that trip to Cyprus to see your family if I was you purely based on any emails from the Cobalt Support Team.
If and when Cobalt do decide to fly from Cardiff I hope your the first one to book a flight and make sure you reserve seat 1A.
