A guide for people with asthma to help them plan their trip.
Health experts advise preparing for a trip four to six weeks before travel.
Take your usual medication, along with a copy of your prescriptions and your:
Things to consider as part of your preparation include:
See your GP or asthma nurse before you travel to review your personal asthma action plan and make sure it's up-to-date.
If you don't have a personal asthma action plan, now is the time to get one. It will allow you to recognise deteriorating asthma and alter your treatment to stay well.
Find out how you can get medical help – such as a local ambulance or doctor – if necessary at your destination. See the Healthcare abroad for more information.
Take spare inhalers in case of loss or theft. These can usually be carried in your hand luggage.
Bring enough medicine to last throughout your trip, plus a few extra days.
Take a print-out of your regular prescriptions, including the generic names of medicines, in case you need medical assistance during your trip or your medication is lost.

If being exposed to feather pillows makes your asthma worse, you could bring your own non-feather alternative or ask your hotel for a pillow with synthetic filling.
If you're sensitive to tobacco smoke, ask your accommodation provider whether you should book a non-smoking room as smoking rules vary from country to country.
Some holiday activities, such as scuba diving, may be hazardous to people with asthma, and special considerations may apply.
Ensure your asthma is fully controlled, as exposure to allergens and viral infections in confined spaces, such as planes and ships, may make your condition worse.
If you're always short of breath, even when resting, you may need a special evaluation before you fly because of the reduced oxygen levels at high altitude.
Carry all your asthma medicines as hand luggage in case your checked-in luggage goes missing or your medicines are damaged in the baggage hold.
Under current security restrictions, you cannot carry containers with liquids, gels or creams that exceed 100ml in your hand luggage.
You can carry essential medicines of more than 100ml on board, but you'll need prior approval from the airline and airport, as well as a letter from your doctor or a prescription.
All asthma medicines taken on board should be in their original packaging, with the prescription label and contact details of the pharmacy clearly visible.

Your doctor or practice nurse can tell you what vaccinations and precautions you need to take for the country you're travelling to.
You can have the usual travel jabs that are recommended for your destination, unless there are other health reasons for not having them.
Tell your doctor or practice nurse if you have recently used high-dose oral steroids before you have any vaccinations.
Asthma and its treatment don't usually interfere with malaria tablets.
Take out travel insurance and check that it will cover your asthma. Many insurers ask you to get permission from your GP before you travel.
Shop around for the best deal. Travel insurance quotes vary depending on your age, medication and destination.
When travelling in Europe, make sure you have a valid European Health Insurance Card (EHIC). The EHIC will entitle you to free or reduced-cost medical care.
However, the EHIC won't cover you for everything that travel insurance can, such as emergency travel back to the UK.
See the Asthma UK website for more information on finding travel insurance if you have asthma.
