It was Sunways!
I flew CWL
-Antalya with them in the 90's ,and could'nt for the life of me,remember the name.
On one particular day of the week,the ramp at CWL
would have 2x MD83 and the 757 from Sunway at the same time.
Used to offer absolutely giveaway holidays at silly prices,which was to be their downfall.
If i remember rightly,a few of the aircraft were seized at UK airports,due to non payment of Fees,Fuel etc.
I was talking to the pilot on the 757,coming back from Antalya to CWL
,and he was British.
He was'nt having much luck,as he'd previously worked with Air Belgium who went under,and then of course with Sunways!
