I don't think its for a TUI airline, i have seen pics of part finished tui a/c on the boeing production line and the painted rudder has part of the tui logo on it. There's no sign of a tui logo on this one
Are you sure? Cause that would be a little confusing to atc:
"Ok 86B squawk 4356"
A few seconds pass... "Um i said only 86B..."
as like four or five numbers come out like that. Ive been to Seattles Boeing field and seen about four or five up in the pattern at the same time. Im not saying that you are wrong but I think that that would be confusing to atc.
When I searched on the registration of the aircraft in this post, I saw different 737's with the same registration, so the aircraft I posted here, is indeed a different aircraft for another airline/customer. There was also a 737-700 for Transavia with the same registration.
