TUI have never been willing to give LBA a proper go, and whoever pins their hopes on TUI expansion really should think again - we’re never going to have a significant TUI presence and we haven’t for decades
Back in the day - pre Doncaster era Tui / Thomson had a very good relationship with LBA and they actively promoted LBA and supported the airports efforts to obtain relaxed night flying hours.
When you look at the cold commercial facts, it’s completely obvious why LBA management pivoted so aggressively.
Thomson may have provided the vital political cover to help the airport win those 24-hour night flying rights in 1994, but a single based aircraft was never going to unlock the airport’s true potential. It was an old school, low-frequency charter model that had hit its ceiling and wasn't providing LBA with the growth it needed.
Then Jet2 turns up in 2003 and completely blows Thomson out of the water. Offering an immediate four-aircraft base with a guaranteed contractual commitment to add at least two aircraft a year for the foreseeable future. It was a commercial proposition no airport operator on the planet could turn down.
Following that, the airport had a spat with Thomson bosses as they were being pushed out of B-Hall. To put this into perspective, it wasn't a case of LBA being deliberately disrespectful to a historic partner, it was a pure capacity play. Jet2 was delivering a massive, high utilisation scheduled network that required priority infrastructure and lightning fast 30-minute turnarounds. Thomson's single aircraft charter operation simply didn't have the commercial weight to demand prime terminal real estate anymore.
Thomson might have used the opening of Doncaster in 2005 as a convenient exit strategy, but looking back, LBA had already backed the absolute right horse for long term passenger volume. Jet2 completely built the modern-day Yeadon we see today.
