If I may please correct you, TUI UK HQ are still based at Columbus House I and II, Westwood Business Park, Coventry. Thomson, and Thomsonfly, have now moved all their operations to Wigmore Place, Luton.
You are not entirely correct with your correction. Areas of Thomsonfly are based at both Coventry and Luton. Ops, inflight retail, airport services, customer services etc are all at Luton. Coventry have the Tfly call centre, scheduled call centre and passenger service unit.
TUI UK is not soley at Coventry either. Coventry mainly has the old Lunn Poly business and much of the new media part of the business. Everything else whether TUI UK, TUI NE, Thomson, Hotels Division, Marketing etc are all in Luton.
If you have to correct people on here, please get your facts straight!
