If you are traveling as a couple on a flight with the seat configuration 3-3, 3-3-3 or 3-4-3, book the aisle seat and a window seat, leaving the seat between you vacant. The middle seat will generally be the last seat booked, so there is a chance the seat may be empty and you score the extra room! Of course, if it does happen to be booked and you want to sit together, you will find that people are quite happy to trade their middle seat for either your window or aisle seat.

There is a common consensus among travel experts that you should avoid eating airline food at all costs. Airline meals typically have a very high salt content, which will speed up the dehydration process.

As with seating, not all airline food is created equal. On some airlines, the food is excellent while others you might as well be eating the in-flight magazine. A great way to get an idea of what the food is like is to check Airlinemeals.net before you travel. Read through the reviews and decide if you should buy food before the flight.

At the end of a long flight you are probably feeling a little worse for wear, even if you have followed every tip from above. Now is the best time to hit the toilet and prepare for landing.
