Looks like the TUI pullout for 2019 is official.
Mark Patterson on BBC Radio Foyle is running a story today on how those who had booked already got notification from TUI that their holiday had been canceled.In fairness they have been rebooked at no extra charge on a Belfast flight the next day and TUI say that it is not specific to Derry - they have canceled several summer 2019 holiday flights across the UK operated by 3rd party airlines due to low demand.
