Did a quick google and found this website
http://www.luzair.com , the website of "Luzair". On the website they offer L1011, 737, A320, A330 and 767 for "Fast response fleet backup". On the fleet pages, the A320s and 330 they list (by MSN) are Air Luxor machines. Not sure what the link-up is, but they seem linked somehow... just not sure how much? Wonder if Luzair are the broker?
