If you are being driven by a friend who wants to see you off, ensure that he / she knows where the short stay parking is located.
If taking a taxi, ensure that the firm you intend to use has taxis available at the time you wish to travel.

Make sure you keep your baggage with you at all times and alert any member of airport staff to any unattended package.
Never look after baggage belonging to other people or carry anything onto the aircraft for someone else.
Keep a close eye on the display boards announcing which gate flights depart from.
