To some countries, it will operate at least three flights a week.
There will be four weekly flights to Antalya and Dalaman in Turkey, as well as to Majorca.
For long-haul, TUI will fly to Cancun three tims a week – four in peak season – and to Orlando Melbourne International, its new Florida gateway, up to three flights a week in the peak.
An increase in flight frequency means TUI is able to offer more 10 and 11 night departures from Glasgow.
Flights to Malaga, Corfu, Paphos and Rhodes will increase to twice weekly this summer.
To offer customers even more flexibility this year, TUI will increase flights to several destinations to offer 10 and 11 night holidays for customers travelling from Glasgow Airport. The number of flights to Malaga, Corfu, Paphos and Rhodes will be increased to twice a week for summer 2022.
Matt Hazelwood of Glasgow Airport said:“TUI’s decision to significantly increase capacity on some of our most popular destinations in Turkey and Spain is very welcome news indeed. We are particularly pleased to see the return of services to Cancun and Orlando, which have historically been extremely popular with our customers.”
