Passenger clothing, health and behaviour

What to wear

In the unlikely event of an emergency the clothes you are wearing can be useful in reducing the risk of injury. The following is recommended:

  • wear natural fibres like cotton and avoid synthetic materials – this is to protect against fire and burns associated with disembarking via a slide
  • wear something non-restrictive and try not to have a lot of exposed skin
  • closed footwear is the best option
  • keep your shoes on during take-off and landing
  • remember to remove high heel shoes before evacuating via a slide.


  • Check the operator´s policy regarding the carriage of passengers with a medical condition (if applicable)
  • Check with your doctor before flying if you have been unwell or have an ongoing medical condition, depending on the severity of your condition you may need clearance from a doctor to fly
  • Ask your doctor or pharmacist about the effects of flying in combination with any medication you are taking
  • If you require prescription medication, carry it on board the aircraft with you and have instructions for its use
  • Ear pain is common during descent, if you are susceptible to ear pain or you are travelling with infants, chewing and or sucking are recommended to help clear the ear. If you have a head cold, a nasal spray may be more effective
  • If you are pregnant and have had no complications it is ok to travel. If you have had any complications or if you are past your 36th week of pregnancy you may require clearance to fly
  • If you are travelling with an electronic medical device, contact the operator for details on the requirements prior to travel.

Deep Vein Thrombosis

Deep Vein Thrombosis (DVT) is a condition usually associated with being immobile. To avoid DVT:

  • drink plenty of (non-alcoholic) fluids during flights
  • regularly mobilise the ankles and massage the calves
  • wear loose, non-restrictive clothing
  • avoid excessive movement around the cabin, as the risk of injury from turbulence may outweigh the benefit of exercise
  • be vigilant for the symptoms of DVT, in particular pain in the calves, during and for up to a month after long flights. If symptoms occur, seek medical advice without delay.

Passenger behaviour

You should not use threatening, abusive or insulting language, or behave in a threatening, abusive, insulting or disorderly manner on board an aircraft. You must not interfere with pilots or cabin crew in the performance of their duties, interfere with aircraft equipment, or disobey any instructions given by a member of the aircraft crew. If you do not comply with these requirements, you may be issued with an infringement notice or prosecuted.

Behaviour which is not tolerated on aircraft:

  • offensive and disorderly conduct such as physical assault, verbal abuse or sexual harassment

  • smoking in any part of the aircraft
  • disobeying instructions of the operator: whether given by signs or by the flight or cabin crew
  • entering an aircraft intoxicated, or becoming intoxicated on board an aircraft.

Unruly behaviour

  • It is against the law to behave in a disorderly, unruly or disruptive manner on board an aircraft. If you do this you can be fined and prosecuted
  • It is a requirement that you follow the instructions of crew members at all times, this is something that forms part of your conditions of carriage
  • The captain can place anyone on board an aircraft that threatens the safety of the aircraft, its crew or its passengers under arrest. In some cases this will involve being restrained by crew.


  • Alcohol has a greater effect on the human body at altitude than on the ground
  • It is an offence to enter an aircraft whilst intoxicated or to be intoxicated on an aircraft
  • If you drink too much alcohol before a flight the airline will refuse to let you board the aircraft
  • The only alcohol you may consume on board an aircraft is that which is provided by the cabin crew
  • You are not permitted to consume your own alcohol once you have boarded the aircraft.
