The story has hit the media now. RYR apologised, but states that contrary to reports about not getting anything to eat/drink, pax were given refreshment vouchers. Seems like a ludicrous response, even if vouchers were handed out, facilities at the airport were closed. RYR didn't comment on pax not being allowed to leave the a/c until someone called the police.
Someone neglected their duty of care...but then again what can you expect, if you pay peanuts, you get Molkeys (old chinese saying)
