Basically, there is MyTravel Airways UK
serving the UK with 2 B757-200s, 3 A321-200s, 14 A320-200s and 3 A330-200s plus 3 B767-300s currently leased to Monarch and Skyservice.
Then there is MyTravel Airways A/S
serving Scandinavia with 4 A320-200s, 5 A321-200s, 3 A330-300s and 1 A330-200.
During the Summer season, there is a fleet swap with some of the A/S A330s joining the UK fleet to supplement the long haul programme and during the Winter, some of the UK A330-200s supplement the Scandinavian fleet during the Hajj period.
Currently flying in the UK is A330-200; OY-VFK and A330-300; OY-VKG.
Hope this helps!
