Just mentioned comments to childminder. Her response (as one of the 2-300 p****d off passengers) was along the lines of
'if they can carry enough fuel to enable them to return to Luton to save the airline money, why the hell don't they carry enough tea and coffee to keep the passengers at least half way on their side'.
I must admit, I see her point - delayed holiday, grumpy captain (apparently), and the only refreshments available have to be paid for, despite the fact that the airline is inconveniencing the passengers for its own commercial ends.
Still, they are all safe and I guess the tour company is going to have to face a deluge of complaints!
