Fit to Fly Certificate Ireland — Same-Day Online Doctor Letter
Airlines can ask for a fit to fly certificate — a doctor’s letter confirming you are medically safe to board — after recent surgery, a fracture in a cast, a hospital stay, or from around week 28 of pregnancy. A registered Irish doctor can assess you today by phone or video for €34.99 and, where appropriate, email you a signed, verifiable certificate the airline will accept — usually within hours.

One certificate per consultation
A sick note and a fit-to-work certificate certify opposite things — that you are unfit for work, and that you are fit to return. Each needs its own clinical assessment, so they cannot both be issued from the same consultation. If you need both, please book two separate appointments. Booking this consultation intending to obtain both does not entitle you to a refund.
Pregnancy — most airlines require a letter from 28 weeks confirming a straightforward pregnancy and your due date. Single pregnancies can usually fly to the end of week 36 (week 32 for uncomplicated twins), but every airline sets its own cut-offs — check yours before booking.
Recent surgery — including keyhole procedures; cabin-pressure changes and immobility raise risks in the first days to weeks depending on the operation.
Fractures and casts — many airlines want confirmation the cast has been split or fitted more than 24–48 hours before departure.
A recent illness, injury or hospital admission — chest infections, cardiac events, a collapsed lung (pneumothorax), or a recent clot each carry their own minimum waiting periods.
Airline or insurer request — sometimes the carrier or your travel insurance simply asks for written medical clearance.
What the doctor assesses
During the consultation the doctor reviews what has happened (operation notes, discharge letters or photos help), your current symptoms, medications, and your airline’s requirements. Where flying is medically appropriate, they issue a signed certificate stating you are fit to fly, with the relevant details — for pregnancy, that includes your due date and confirmation the pregnancy is uncomplicated.
Each certificate carries a unique reference that airlines can verify online, and it is emailed to you as a PDF the same day.
Some situations can’t be cleared remotely. Chest pain or breathlessness at rest, a suspected new clot (hot swollen calf, sudden breathlessness), an unresolved collapsed lung, or being unwell right now need in-person medical care — not a certificate. If the doctor finds flying unsafe, they will tell you honestly rather than sign — the fee covers the assessment, not a guaranteed outcome.
How it works
Book a time above — same-day slots are usually available, seven days a week.
Speak to a registered Irish doctor by phone or video. Have any hospital letters, your airline’s policy and travel dates to hand.
Receive your certificate by email as a signed PDF with a verification reference — typically the same day.
Flying long-haul after surgery or a leg injury? Ask the doctor about clot prevention — movement, hydration and, where appropriate, compression stockings meaningfully reduce the risk of a deep-vein thrombosis on flights over four hours.
Frequently asked questions
Will airlines accept an online doctor’s certificate?
Yes — the certificate is issued and signed by a registered Irish doctor and carries a unique reference the airline can verify online. Always check your airline’s specific wording requirements (especially for pregnancy) and bring a printed or digital copy to the airport.
How quickly can I get it?
Usually the same day. Same-day consultations are typically available, and the certificate is emailed as a PDF shortly after the doctor completes the assessment.
What weeks of pregnancy need a letter?
Most airlines ask for a doctor’s letter from 28 weeks. Uncomplicated single pregnancies can generally fly until the end of week 36, and uncomplicated twins until week 32 — but limits vary by airline, so check yours before booking the consultation.
Can I fly with a cast?
Often yes, but many airlines require the cast to have been fitted or split more than 24–48 hours before departure, and you may need extra seating arrangements. The doctor covers this in your assessment and letter.
What if the doctor decides I’m not fit to fly?
The doctor will explain why and what needs to change before flying is safe. The consultation fee covers the medical assessment itself — a certificate is only issued where flying is genuinely safe, which protects both you and your travel insurance.
Is this the same as a fit to travel certificate?
They overlap. Fit to fly is specific to air travel and airline rules; a broader fit to travel certificate covers cruises, tours, insurance and other travel where an operator wants medical clearance.
