Been keeping an eye on the TUI NCL movements on FR24 and if I was still standing on the airport roof - and getting regs for a log book (1980’s esque ) would love the variety of aircraft visiting and swapping. In other years TUI have usually based 3 737’s and swapped them every few months at most. Bearing in mind the comments above is there a specific reason for all these swaps this year. Is it more engineers available at NCL than elsewhere, or less engineers available so aircraft can’t stay long or any other reasons (some insight would be interesting pleae).
