I am in the USA and I tried to get in touch with Tui, for 2 days, before I got through to a human being, I wanted to upgrade my seats for my return journey, but was told I cannot do it, they alway have premium seats left, as they are expensive, but they still would not upgrade my seats, I have used TUI, plenty of times, but will not be booking with them again, as the customer service department is rubbishs.
