Snacks in the airport.

Many times flight combinations when travelling to/from your Erasmus place force you to spend many hours in the airport so you should prepare things to do during these periods. A good way to spent time and keep awake is eating. You always can find many places to eat in the airports, but they are usually quite expensive. Bring always with you something to eat. Pieces of fruit, sweets, snacks or sandwiches are always welcoming. But it is shame that you can not bring water with you since it is usually quite expensive in airports.
