Medical advice for passengers

Before you fly

Your GP

  • Visit your GP at least 15 days before you leave for certificates, prescriptions and vaccinations
  • Have your ears and teeth checked (panoramic X-ray)
  • Have repatriation insurance, accident/illness coverage, a European Health Insurance Card, your passport, your vaccination record and your blood group card.

    Pregnant women
    Being pregnant does not mean you can’t travel, but it is always best to seek medical advice first. Travel during the last month of pregnancy should be avoided, however, and also during the first week after giving birth.
    - Dress comfortably and wear tights and/or compression stockings to aid with blood circulation,
    - Stay hydrated,
    - Attach your seatbelt below the abdomen (in the pelvic area).

    Cases of chickenpox in children
    If your child has chickenpox, wait until he or she is no longer contagious. In order to fly, you must present a medical certificate of non-contagiousness if there are still lesions visible. Without this certificate, you may be refused access to board the aircraft.
    Chickenpox is a highly contagious viral infection that can be quite severe in adults and vulnerable people such as pregnant women, newborns, the elderly, etc.

    Extra oxygen on board
    If you require extra oxygen on board, the airlines may suggest one of the following: 
    - You bring your own portable oxygen concentrator (subject to approval from the airline, depending on the model of concentrator)
    - The airline arranges for a supply of extra oxygen on board. 
    You should make the request when booking your tickets.

    Flying with a plaster cast: certain measures apply
    If you must fly with a plaster cast, certain measures apply. 
    When you board the aircraft, 
    you must present a medical certificate stating that you are fit to travel with a closed cast. Without this certificate, you may not be allowed to board the aircraft.
    * The medical certificate must give the date when the cast was put on.


  • Vaccinations should be administered before going abroad depending on the destination, duration and conditions of travel, your medical history and previous vaccinations
  • Several vaccinations can even be administered on the day of departure
  • Where to get vaccinated:
    You must go to an authorised centre for vaccinations against yellow fever and Japanese encephalitis. Your GP can administer other vaccinations
  • When to get vaccinated:
    At least 15 days before you leave, as early as possible (1 month for yellow fever if first vaccination)

Air travel & jet lag

  • For ear problems, swallow regularly or chew chewing gum. If this is not enough, squeeze both nostrils, close your mouth and breathe out through the nose.
  • For travel sickness, choose a seat in the middle of the aircraft.
  • To avoid the risk of phlebitis (inflammation of veins), wear compression socks or stockings and get up and walk around regularly (30 mins, aisle seat).
  • Drink plenty of water (1 L every 4 hrs).
  • Prepare for the time difference by eating at the meal times of your destination (expect 1 to 2 days to get used to the time difference).
