Hello,
Without needing a based aircraft for most of the time, the ACL winter season report (
http://www.acl-uk.org/UserFiles/File...n%20Report.pdf) shows that Wizzair have slots to increase their movements at Luton by a massive 34% compared to last year, with over 30 departures per day.
This gives them 35-36% of Luton's allocated movements and available seats this winter (compared to 44-45% for Easyjet and a mere 10% for Ryanair).
Incidentally, there are slots for Tuzla - Luton, but no flights have been announced (yet).
The way that the Wizzair operation has grown at Luton is very impressive, as that photo suggests.
