The Belgian Dutch
TUI Nederland has been using for many flights other planes, including its sister company TUI Belgium... On this day, the AMS-FNC-AMS flight was made with TUI Belgium B738 OO-JBG with a very nice captain...as he was taxiing we noticed the open window as he was already waving to the spotters :) Hope you had a great flight back! Holding off runway 05 while other traffic takes off (notice the taking off plane?)
