Travel letter FAQs

Your questions, answered

What is a fit-to-fly letter?

A fit-to-fly letter is a short medical letter, signed by a doctor, confirming that you are medically fit to travel by air. Airlines and travel insurers may ask for one if you are pregnant, have a medical condition, or have recently been ill, injured or had surgery.

How much does a fit-to-fly letter cost?

A fit-to-fly letter from Prompt Medical costs £49. Travel medication, vaccination and infection-clearance letters start from £45. You see the exact price before you pay, and you get a full refund if the doctor cannot issue your letter.

How quickly will I get my letter?

We aim to issue approved letters the same day once we have all the information we need. This is a target, not a guarantee, so please request your letter as early as you can before you travel.

Will my airline accept the letter?

Our letters are signed by GMC-registered doctors and may carry a unique Document ID and QR code for verification. Acceptance is always the airline or travel provider's decision, so please check their requirements before ordering.

Do I need a fit-to-fly letter if I'm pregnant?

It depends on your airline and how far along you are. Many airlines ask for a letter later in pregnancy, but each sets its own rules. Check your airline's policy, and we can issue a pregnancy fit-to-fly certificate where clinically appropriate.

Do I need to see a doctor face-to-face?

Not usually. Most travel letters are completed online after a doctor reviews your questionnaire and evidence. A video or telephone call is only arranged if the doctor needs more information.

What if the doctor can't issue my letter?

Then you get a full refund of the service fee. Every letter needs a proper clinical review, and we only issue it where it is medically justified.

Can my GP write a fit-to-fly letter?

Some GP surgeries do, usually as a private, paid service, but many do not write fit-to-fly letters at all, and others ask you to allow up to 28 days. Prompt Medical aims to issue approved letters the same day once we have the information we need.

Can I use Prompt Medical if I'm not in Leicester?

Yes. Online travel letters are available across the UK. You do not need to visit our Leicester clinic.

In plain English

What is a fit-to-fly letter?

A fit-to-fly letter is a short medical letter, signed by a doctor, confirming you are medically fit to travel by air.

Airlines and insurers often ask for one if you are:
  • Pregnant, usually later in pregnancy
  • Living with a medical condition
  • Recovering from illness, injury or surgery

A GMC-registered doctor reviews your details online and, where clinically appropriate, issues it as a signed PDF. Carrying medication, recovering from an infection or going on a cruise? There is a matching letter for that too.
