From time to time - computers go wrong and the "no meal" passengers are unrecognisable from those who have paid....therefore - everyone is going to get a meal....
in general - those with no meals booked will be sat nearer to the back of the aircraft....nothing to do with galley location i may add - largest galleys on all TCX aircraft are at the back ...
depending on the standard of hotel or brochure that you book through - you may automatically receive a meal onboard and are not aware of the option of not having one.....
sometimes....the crew just get it wrong by not reading the list of no meal passengers or checking with the passengers documentation....
so many variations and options.....
