- Domestic flights - check in 1 hour prior to departure
Hand Luggage - What Not To Pack
You should always check the exact hand luggage allowance with your airline prior to packing. A general guide is that hand baggage should be a maximum weight of between 5 & 7 kilos, and dimensions should not exceed height 450mm x width 350mm x depth 200mm. Most airlines have a hand baggage measurement gauge at check-in.
Take only one piece of hand luggage and make sure that it does not contain:
- Scissors / Razor blades
- Knives with blades of any length / Household cutlery
- Tweezers / Hypodermic needles (unless required for medical reasons)
- Tools Toy / replica guns (metal or plastic) or Catapults
- Knitting needles / Sporting bats
- Billiard, snooker or pool cues / Darts
If items are confiscated at security control you will not be compensated and, with the exception of unusual circumstances, the confiscated items will not be returned.
Syringes that are needed for diabetics and other medical reasons will only be allowed in hand luggage if you can prove the medical necessity. Phone the airline in advance to find out what they require as proof of your medical condition.
