Travelling when you're pregnant

For your and your baby’s safety, you cannot fly after:

We recommend you carry a letter or statement from your Doctor or Midwife confirming:

Travelling with medicines, medical supplies or medical equipment

Here's some key information for travelling with medicines, medical supplies or medical equipment. If you have any additional questions please contact PMCU.

Medical equipment Notes
Asthma inhalers
  • You can take asthma inhalers in your hand or checked baggage.
CPAP machines
  • Medical clearance is not needed to travel with or use a CPAP Machine for sleep apnoea on board our aircraft. However, we recommend that you carry a letter from a medical professional stating why you need the machine for your journey.
  • You can carry your device in the cabin as an extra piece of hand-baggage without charge.
  • If you don’t need to use your CPAP machine in the cabin, and you want to check it into the hold, it will be permitted in addition to your free baggage allowance without charge.
  • If you need to use your CPAP machine on board, you will need a DC adapter to plug into the in-seat power supply where installed. We recommend always carrying a dry cell battery for your device should seat power not be available.
  • The maximum output of our in-seat power supply is 75 watts. If your machine needs a stronger output, you will need to bring a dry cell battery to power it.

More about in - seat power (pdf English only)

Gas cylinders for mechanical limbs
  • You can take non-flammable, non-toxic gas cylinders worn for the operation of mechanical limbs in either your hand or your checked baggage. If required, you can also take spare cylinders of a similar size to ensure you have an adequate supply during your journey.
Epipens and hypodermic needles
  • You can take epipens and hypodermic needles in your hand baggage (with a doctor's note/prescription) or in your checked baggage.
Liquid medication
  • You can take liquid medication in your hand or checked baggage.

  • If you might need it during your journey, place it in your hand baggage. You can then carry as much as you need for your trip, even if this exceeds the usual limit on liquids, provided you have a supporting prescription or doctor’s note. The medicine does not need to fit in the transparent bag but you should have it ready for inspection by airport security.

  • 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 on board.
Oxygen cylinders
  • We will only carry personal oxygen or air, gaseous, cylinders required for medical use if we're unable to provide the required flow rate on board. To take these items with you, you need to get medical clearance before you fly.

  • If you'd like to take oxygen cylinders for use at your destination, you will need to contact us to get approval.

  • Once approved, you can carry oxygen or air cylinders of max. 5kg gross weight in your hand or checked baggage.

  • You should carry sufficient back up battery supply to cover a minimum of 150% of your entire travel time (including flight and transiting time).

Food allergies

In-flight meals

We source food from all around the world and not every country considers the same food ingredients to be potential allergens. On UK-bound flights, allergen labelling on the packaging may not reflect all the allergens listed under UK legislation.

When booking travel, customers can order a special meal. However, note that staff (including call centre staff) are unable to share personal allergen information with cabin crew. When travelling with us, you must therefore inform your cabin crew of your food allergy upon boarding your flight.

To assist with food allergies

  1. If you have a food allergy, we can offer a range of special meals that exclude a variety of potential allergens e.g. seafood, dairy, eggs and gluten. Information on special meals can be found here.
  2. You can bring your own food on board.
  3. Upon request and following boarding, cabin crew will be able to provide information relating to the allergens contained within the meals served. In some instances, meal packaging will also provide this information.
  4. To allow for cleaning and inspection of seats, customers will be able to pre-board the aircraft following presentation of a medical letter for the epinephrine/adrenaline auto-injector to staff at the gate. Customers must bring their own suitable wipes.

Please note the following

  1. We cannot guarantee an allergen-free cabin environment or prevent other passengers from bringing their own food on board. Meals containing tree nuts may continue to be served throughout the aircraft and tree nut based snacks may also continue to be served in other cabins of travel depending on the aircraft type. 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.
  2. We do not currently offer any special meals free from sesame, tree nuts, lupin, soya, sulphites, mustard or celery.
  3. For customers consuming food of their choice, not provided by the airline - we are unable to heat or refrigerate any food items you might bring with you. If you prefer to consume your own food, we suggest non-perishable food. Please also check the different quarantine laws of your transit and/or destination with respect to food types permitted into the country.

Guidance for Peanut, Tree Nut or Sesame allergy sufferers

  1. Our in-flight meals do not contain peanuts or peanut products. However, they may be produced at a facility that handles peanuts. We are unable to offer a peanut-free special meal.
  2. We do not provide a special meal option for customers with tree nut or sesame allergies.
  3. We cannot guarantee an allergen-free environment while travelling with us.
  4. Upon request, Cabin Crew will make an announcement so that other passengers are aware of your allergy. Cabin Crew will also suspend the serving of loose nut snacks in your cabin of travel.

Severe allergic reactions (anaphylaxis)

Severe allergic reactions on board are rare, but if you suffer from a severe allergy always speak to your doctor before you book to discuss potential risks and how you can minimise becoming ill on your trip.

Here are a few examples of how you can prepare:

Anaphylaxis campaign website

Spraying the cabin

We are required by the World Health Organisation (WHO) or local Health Authorities to spray the inside of the aircraft before arrival into certain destinations to prevent the risk of insects spreading highly dangerous diseases, such as malaria and dengue fever.

On routes where we are required to spray, cabin crew will advise 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:

For flights to Australia, the aircraft must be sprayed prior to departure from Singapore with a Permethrin insecticide spray.

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:
