TUI post booking service
A first world problem I know but having recently booked a TUI holiday with a flight from Manchester to Cancun I've tried to update my booking using their app to include Champagne and Chocolates on the way out. I'm finding I just get and error message on their app, they are not contactable by phone and the TUI stores is unable to help. Not a big deal I know but you would think airlines would want customers to pay for those little extras.
