If you're someone who likes to get to the airport early before a holiday abroad, you'll be well used to being at the mercy of terminal prices for food and drink while you wait for your flight.

However, many of us will not be aware that there are in fact different rules for food though - and you could save a packet by bringing your own meal with you to the airport.
