Travelling if you have a medical condition

White cross on green background.

Travelling if you have a medical condition can be daunting but most of the time you can travel without doing anything any differently. Sometimes you may need to take precautions and this information will help you understand what you need to be aware of.

We also recommend you buy suitable medical insurance as medical charges and repatriation costs can be very expensive depending on the country you are visiting. We offer you the opportunity to buy travel insurance as part of your flight booking but it is only available for some countries. If it's available you will see the option when you are confirming and paying for your flights.

Medical clearance and fitness to fly - am I fit to fly?

Some medical conditions mean you need to talk to us before your flight so we can make sure you are fit to fly.

Conditions that may require medical clearance are:

You will need to complete part one of our MEDIF form and ask your doctor to complete part two. Once you have sent the form to our Passenger Medical Clearance Unit (PMCU) we will be able to consider your request and tell you whether you are fit to fly.

Download the MEDIF form (pdf, 650kb, English only)

We assess your fitness based on internationally accepted criteria so we can be sure you have a safe and comfortable flight. In some cases we may ask for additional information or ask you to travel with a medical escort or supplementary oxygen.

In-flight oxygen

If you need to use oxygen on board you must book it in advance. We can only provide oxygen to one passenger per flight so availability may be restricted. The medical information form needs to be completed by you and your doctor before we can clear you to travel. We cannot provide oxygen on the ground at any airports.

British Airways has introduced the Avia Technique Pulse dose cylinder onboard our A380 and B787 aircrafts. The Pulse dose uses less oxygen as it is provided ‘on demand’. Please ensure that your doctor completes Part 2 of the MEDIF form to confirm that you can use the pulsed oxygen system.

How to request medical clearance

Travelling with medicines or medical equipment
  • Always remember to pack your medication in your hand baggage, if possible in its original packaging.
  • We cannot help you keep your medication cool. Please talk to your pharmacist about your options.
  • If you are flying with medical equipment you may need to contact us for clearance. There are more details further down this page.
  • All equipment must be able to work from a battery, as we cannot guarantee a power supply on board.
  • In most circumstances you can use authorised medical equipment on board, except during taxi, take-off, approach and landing.
  • If you need to use essential medical equipment at your destination that will exceed your luggage allowance, please contact our PMCU.

If you have any additional questions please contact our PMCU.


You can use a battery-operated nebuliser on board except during taxi, take-off, descent and landing. It is not possible to supply mains power.

CPAP machine

  • You do not need medical clearance to travel with or use a CPAP machine for sleep apnoea.
  • These machines can use an adaptor to plug into a laptop power point if it’s available. We do recommend using a dry cell battery to operate your machine just in case the power point near your seat is not working.
  • The maximum power output of our laptop point is 75 watts. If your machine needs more power than this then the power point will automatically switch off.

Portable dialysis machines

Most of the time you can take this equipment on board or pack it in your checked baggage. If this means you will exceed your free baggage allowance, contact our PMCU otherwise you may be charged at the airport for your overweight bag.

Portable Oxygen Concentrators

A portable oxygen concentrator (POC) can be carried on board as part of your hand baggage allowance if it is approved by the Federal Aviation Administration (FAA). If you think that you'll need to use your portable oxygen concentrator during the flight, please contact PMCU to obtain medical clearance before you fly.

You should carry sufficient back up battery supply to cover a minimum of 150% of the planned flight (including transiting time).

Hand baggage allowance

Disposal of medical equipment

If you need to dispose of needles, lancets, syringes or empty insulin cartridges on board please ask the cabin crew for the sharps box; do not leave the items in the toilets or seat pockets.

Travellers' thrombosis (DVT)

Traveller’s thrombosis or deep venous thrombosis (DVT) is a blood clot that forms in a vein, usually in the lower legs. Research has confirmed that if you are sitting in an aircraft, car, bus or train for more than four hours the risk of a blood clot forming may increase.

Factors increasing the risk of DVT include:

  • being over the age of 40
  • suffering previously from DVT or a pulmonary embolism or someone in your close family suffering from it
  • use of oestrogen-therapy, oral contraceptives ('the Pill') or hormone-replacement therapy (HRT)
  • pregnancy
  • recent surgery or trauma, particularly to the abdomen, pelvic region or legs
  • cancer
  • some inherited blood-clotting abnormalities and other blood disorders

If you think any of the factors above may affect you, seek medical advice before travelling. You may be advised that compression stockings or anti-coagulant medication may help to avoid the possibility of DVT.

You can reduce the risk of DVT by:

  • drinking normal amounts of fluid
  • avoiding alcohol and caffeine
  • avoiding smoking
  • avoiding crossing your legs when you’re sitting down
  • taking a walk around the cabin regularly
  • standing in your seat area and stretching your arms and legs
  • doing regular foot and leg exercises during the flight
  • wearing loose fitting comfortable clothes when you’re travelling
Travelling when you are pregnant

We understand that pregnancy is not a medical condition but for your safety, and your baby’s, you cannot fly after:

  • the end of the 36th week if you are pregnant with one baby
  • the end of the 32nd week if you are pregnant with more than one baby

After 28 weeks you must carry confirmation from your doctor or midwife (such as a letter or certificate, in addition to your pregnancy record) confirming your approximate due date and that there are no complications with your pregnancy.

Guidance for Diabetics

If your diabetes is stable you can fly with no restrictions, however you need to take care that you look after yourself during your trip.

  • If you are crossing time zones make sure you know how to manage your insulin regime throughout the trip.
  • You should carry your insulin in your hand baggage otherwise it may freeze in the hold.
  • Your insulin should be in the original packaging, easily identifiable and accessible during the flight.
  • Always carry a prescription or supporting letter from your doctor to avoid delays at security or customs.

Advice from Diabetes UK

Advice for food allergy sufferers

Food allergies vary by type and severity. Common allergies include peanuts, tree nuts, gluten, dairy, shellfish and strawberries. You can request a special or medical meal to exclude a variety of potential allergens e.g. seafood, dairy and gluten.

Travelling with food allergies

Special meals we can offer you

Anaphylaxis campaign website

Severe allergic reactions on board are rare, but if you suffer from a severe allergy you may want to consider the following precautions before you fly.

Cabin environment

We cannot guarantee a nut free cabin, or prevent other passengers from bringing their own food on board. We use the recommendations of the International Air Transport Association (IATA) for allergen sensitive passengers to make sure your flight is as comfortable as we can make it.

Always speak to your doctor before you book to travel to discuss the potential risks and how you can minimise becoming ill on your trip. If you have been prescribed an epinephrine/adrenaline auto injector like Epipen, Anapen, Twinject or Jext make sure you carry this with you in your hand baggage, clearly labelled and accessible throughout the flight in the seat pocket or on you personally. We also recommend you tell the people around you where you have placed the medication and what to do in an emergency just in case.

Being prepared

Please talk to your doctor about the many things you can do to be prepared in case you come into contact with an allergen.

Here are a few examples to think about:

  • Wear a medi-alert bracelet.
  • Advise cabin crew and the people seated next to you of your allergy and that you are carrying medication. Our cabin crew can speak to people seated near to you to help explain your allergy.
  • Ensure your medication is easily accessible.
  • Cabin crew are trained to recognise symptoms of anaphylaxis and administer treatment but if you are travelling with family, friends or guardians they would be expected to treat you first.
  • Clearly label your medication to show who it should be administered to.
  • Carry an emergency treatment plan and a letter signed by your doctor so you can minimise delays at security going through the airport as you will have your medication in your hand baggage.

British Airways are unable to heat or cold store any food items you might bring with you, so if you do prefer to consume your own food, non-perishable food is best. You should also check the different quarantine laws of your transit and/or destination with respect to food types permitted into the country.

Spraying the cabin

We are required by the World Health Organisation (WHO) to spray the aircraft cabin on arrival into certain destinations to prevent the risk of insects spreading highly dangerous disease, such as malaria and dengue fever.

On routes where we are required to spray, cabin crew will read out a brief statement advising you that spraying is about to take place. This will give you the opportunity to cover your eyes and nose if you wish.

The spray clears from the aircraft in a few minutes.

Contents of the insecticides

The sprays contain synthetic pyrethroids, which are widely used.

The World Health Organisation (WHO) assesses the safety of insecticides and recommends the use of the following synthetic pyrethroids:

  • D-phenothrin, which has lethal effects on domestic insect pests. It is used against mosquitoes, houseflies and cockroaches.
  • Permethrin, which is a broad spectrum insecticide used against a variety of pests.

N.B. Aircraft entering Australia and New Zealand need to be sprayed twice - initially with Permethrin residual insecticide and then with a Phenothrin spray.
