I'm not sure of XL's expansion policy, but this summer seems to be a heavily contracted schedule compared to that of the last two summers, is this because XL are now more focused or what? To use EMA as an example (though I'm aware XL has withdrawn or scaled back from other airports) over the last two years the airline hasn't based it's own aircraft here, instead using XL uniformed crews but MD-83s of Viking Airlines under the brands Air Scandic in S05 and UKJet in S06. This summer they're using Air Malta and bmi for XL flights, as well as one or two XL W-pattern flights. The airline seems to be on a big marketing push with the XL.com brand, but they seem to almost always use other airlines to operate their flights, and have recently closed CWL & HUY.
