Medical conditions

There are some medical conditions that require your doctor to confirm that it's safe for you to fly. If you're not sure whether this applies to you then speak to your doctor first.

A medical clearance assures us that your doctor is happy for you to fly with us, and that you will have a safe and healthy journey to your destination. 

Here's a few examples of conditions that may need to be cleared before you travel:

  • Recent surgery or injury
  • Existing medicaal conditions that require current consultant visits
  • Contagious diseases or ilnesses
  • Intention to seek medical treatment abroad
  • Oxygen, or carriage of some respiratory equipment
  • Harness requirement

Our team may ask you to fill out a medical clearance form which we will use to ensure that it is safe for you to travel.

Flying with a plaster cast

If you’ve got a recent fracture that has been treated with a complete plaster cast, you must not fly within 48 hours of being treated. However If the plaster is a split or back slab type and does not fully enclose the limb then there will be no problem and you are fit to fly.

  • Broken Limbs: Any plaster cast must have been set in place for over 48 hours for legs and 24 hours for arms. In the case of a full leg plaster, where the leg can’t be bent, 2 additional seats must be purchased.

Want to know more? Air trapped inside a plaster cast which has fitted less than the times given above may expand at cabin cruising altitude. This, combined with the swelling of the limb following a fracture, will cause severe pain and might damage the limb further.

If assistance is required, seating will be automatically added for the passenger and a medical companion. Passengers can take crutches or a walking stick on board the aircraft.

Flying with a contagious disease?

We’re naturally keen to prevent you and our passengers from falling ill, so we have guidelines for travelling with certain conditions. As the following illnesses can be contagious, we’ve put together the following information to help you decide whether to fly or not. The list below is not exhaustive but just a few examples of more common conditions that can arise. Please contact us if you have other symptoms.

Chicken pox

  • Children who have the early signs of the disease are advised NOT to travel as this is the most infectious time. Once the rash begins to dry-up and the blisters form dry scabs the patient is no longer infectious. The child is usually fit to travel after seven days from the first appearance of the rash.


  • Customers with Measles should not fly until the condition has completely resolved.


  • Customers with symptoms of mumps should not fly until the condition has completely resolved which is usually after 10 days.

Shingles (Herpes Zoster)

  • Customers with shingles are not considered to be infectious especially if the shingles rash is on a covered part of the body. Shingles on the face or in the eye can be very unsightly and these customers shouldn’t fly until they’ve consulted their doctor. Customers returning home with facial or ophthalmic shingles should obtain a ‘fit to fly’ letter. In the event that a doctor’s note is required, this should be dated within 3 months of the date of travel and fitness to fly certificates should be dated within 7 days of the date of travel.

Any allergies?

Peanuts and nut products are sold on-board Thomas Cook aircraft. Please advise a member of our crew once on-board the flight of your allergy - the cabin crew can suspend the sale of nut products during that flight.

The cabin crew will also make an announcement to other customers requesting where possible, to refrain from consuming their own nuts whilst on-board the aircraft. However, we can’t forbid customers from eating food containing nuts on-board.

Customers flying with our sister airline Condor who have a nut allergy can fill in a form where the allergy is declared. Please contact us for a copy of the form. If you’re travelling on a different airline then there may be a different policy on allergies. Please contact the airline you are flying with for further information on their specific policies.
