I was reading an article on what whould constitute a meal for regulation 261/2004 see http://www.flightmole.com/delay_meal.htm

The regulation apparently does not give guidance of what constitutes a "meal" and I was wondering how this should be interpreted.

It may be that airlines simply give a ridiculously low amount-say 5 Euro meal voucher for a "meal" hoping that this will appease passengers. Other airlines might be more generous.

Does this vary between countries and cultures?

Are some airlines more generous than others. Do airlines make a greater catering effort for First than Economy?

Should the passenger be given at least the same cuisine as the flight crew when there is delay? Have passengers made their own catering arrangements and then sought reimbursement from the airline concerned?

I would be interested to know of different experience for when this next happens to me. Perhaps this has been considered before if so perhaps someone could point me to the correct thread.
