What happens if I’m not fully recovered from chickenpox?
If our doctors feel the chickenpox spots are not fully scabbed over, and that you or your child are still infectious, they will issue a letter stating that you are ‘Not fully recovered’ and ‘Not fit-to-fly’. This can be used for insurance purposes and rearranging flights with your airline or travel company.
Chickenpox can cause problems with immunocompromised individuals and during pregnancy. Our doctors have a clinical responsibility to ensure that we only sign off patients to travel who are no longer infectious.

Can you fly with chickenpox?
You generally cannot fly with active chickenpox. The virus is highly contagious and spreads easily in an enclosed cabin, so most airlines will refuse boarding if the rash is still weeping or new spots are appearing. You can usually fly once all of the spots have dried and scabbed over, no new spots are forming, and you are no longer infectious.
Chickenpox is infectious from around 1 to 2 days before the rash appears until every blister has crusted over, which usually takes about 5 to 7 days after the last new spot (NHS guidance on chickenpox). Airlines count the waiting period from the last new spot, not the first, so the clock resets each time a fresh spot appears.
Because cabin crew cannot judge whether someone is still contagious, most airlines ask for a fit to fly certificate from a doctor. The certificate confirms that all lesions have scabbed over and the passenger is no longer infectious, which is what allows the airline to board them with confidence.
When is it safe to fly after chickenpox?
As a practical checklist, you are usually considered fit to fly once:
- Every spot has fully dried and scabbed over, with no open or weeping blisters.
- No new spots have appeared for at least 24 hours.
- Any fever or feeling of being unwell has settled.
- A doctor has confirmed in writing that you are no longer infectious.
Airline rules for flying after chickenpox
Policies differ by airline, and most set their own waiting period counted from the last new spot. The table below shows the typical requirements of major carriers. Airlines review these rules regularly, so always confirm directly with yours before travelling, and carry your fit to fly certificate with you.
| Airline | Typical waiting period | Doctor’s letter | Notes |
|---|---|---|---|
| British Airways | 6 days after the last new spot, once crusted | Required | Confirm via BA’s medical clearance team where symptoms are recent. |
| easyJet | 7 days after the last spots have scabbed | Recommended if symptoms visible | A letter avoids questions at the gate if any marks remain. |
| Jet2 | 7 days after the last new spot | Fit to fly letter required | Letter must confirm the passenger is no longer infectious. |
| Ryanair | 7 days after the last new spot | Recommended | Documentation confirming fitness to travel is advised. |
| TUI | 7 days after the last spot, fully scabbed | Fitness to fly letter required | Package and flight-only bookings both apply. |
| Virgin Atlantic | 7 days after the last spot, all scabbed | Recommended | Carry the letter with you for boarding. |
| Etihad Airways | 6 days after the last spot, if dry and crusted | Required | Confirm with Etihad medical services for recent cases. |
| Qantas | Once every spot has dried and crusted | Recommended | No fixed day count; based on lesions being crusted. |
| Aer Lingus | 7 days after the last new spot | Recommended | Carry medical confirmation of fitness to travel. |
| KLM | Once the scabs are dry | Required | Medical clearance may be requested. |
Some airlines use their own medical form or specific wording. If yours does, contact ZoomDoc before ordering and our doctors can complete the correct form alongside the standard certificate.
What is a medical certificate for chicken pox?
A medical certificate for chicken pox, also called a chickenpox fit to fly certificate or recovery letter, is a signed document from a GMC-registered doctor confirming that the person named on it has recovered to the point of being safe to travel. It is the document airlines and, in some cases, travel insurers ask for as proof that the traveller is no longer infectious.
What your certificate confirms
Your ZoomDoc certificate is a verifiable digital PDF, signed by a UK doctor, containing:
- The name and date of birth of the person travelling.
- Confirmation that the chickenpox spots have fully scabbed over and no new spots are appearing.
- An explicit statement that the person is no longer infectious and is fit to fly.
- The travel or departure date where relevant to your airline.
- The GMC registration number of the issuing doctor, which airlines use to verify authenticity.
- A QR code enabling an instant verification check, plus ZoomDoc Health contact details.
Who needs a chickenpox fit-to-fly certificate?
The certificate is the same document in each case, but the circumstances below reflect the most common situations our doctors see, and the specific questions families and travellers bring to them.
A child recovering before a family holiday
Chickenpox in children often lands days before a booked holiday. Once your child’s spots have scabbed over and no new ones are appearing, upload a short video showing the scabbed spots and our doctors can confirm they are fit to fly. Each child travelling needs their own certificate.
Common questions: Can my child fly a week after chickenpox? Does a toddler need a fit to fly letter? Will the airline let my child board with fading marks?
An adult with chickenpox before a flight
Chickenpox in adults tends to be more severe and can take longer to scab. If you have recovered and your spots have crusted over, a certificate confirms you are fit to travel and no longer infectious, which is often needed for work travel and long-haul flights.
Common questions: Can adults fly with chickenpox? How long after chickenpox can I fly long-haul? Do I need a doctor’s note to fly after chickenpox?
Exposed to chickenpox but no symptoms yet
If someone in your household has chickenpox but you have no symptoms, you may still be able to travel. A doctor can assess your current status and confirm fitness to fly. Note that some airlines restrict non-immune passengers recently in close contact, because symptoms can develop during the incubation period. Contact us with your travel dates and we will advise.
Common questions: Can I fly if my child has chickenpox but I don’t? Can you fly if you have been exposed to chickenpox? How long is the chickenpox incubation period before flying?
A flight in the next day or two
Late diagnoses and tight departure dates are the most common reason people come to us rather than waiting for a GP appointment. With an average turnaround of around 1 hour during operating hours, you can apply the same day your spots have scabbed and still make your flight.

Frequently Asked Questions
What will happen after I purchase a chickenpox recovery fit-to-fly certificate?
After purchase, we will provide you with your unique certificate booking reference number, which will allow you to upload your medical evidence.
Once uploaded, our doctors will review your evidence on the same day (between 9am and 9pm GMT, 7 days a week) – they may call you if they have any questions.
Once validated, we will send your fit-to-fly certificate to you by email and SMS.
Can I change my flight if my child has chicken pox?
Your eligibility to change or cancel a flight due to chickenpox will differ depending on the company you are flying with. It is always important to check refund and cancellation terms before booking a flight.
Some airlines will allow booking changes due to illness if you can provide medical proof of your condition, such as a ‘Not Fully Recovered’ or ‘Not Fit-to-Fly’ letter. When applying for a fit to fly letter for chicken pox, if our doctors determine that you are not fully recovered from your condition then they will supply a certificate of proof that you can show your airline to evidence your condition.
How do you prove you have chicken pox?
Chicken pox are relatively easy to diagnose, and most doctors will be able to confirm whether you have chicken pox based on a visual examination. For this reason, ZoomDoc’s doctors can usually diagnose a patient with chicken pox or confirm a chicken pox recovery with a simple video diagnosis.
Once your chicken pox has been diagnosed you can get a medical letter that confirms recovery, or one that confirms the condition is still present, which can be used as evidence for a variety of reasons such as work or travel.
What is a fit-to-fly certificate for chickenpox
A chicken pox fit- to-fly certificate is a letter that confirms your chicken pox has scabbed over, and no longer pose a risk of infecting others.
Chicken pox can be highly contagious, and as such it is paramount that you confirm you no longer pose an infection risk if you are about to be in close proximity with other people, such as on a flight or at work.
Can I go to work if my child has chickenpox?
Chicken pox is highly contagious, and can even pose an infection risk up to 2 days before a rash appears. If your child has chickenpox then you should contact your workplace immediately to confirm their policy, as you may also be able to infect others even if there are no visual signs you have chicken pox.
Can you fly with chickenpox?
Most airlines will not let you board with active chickenpox, because the virus is contagious and spreads easily in a closed cabin. You can usually fly once every spot has fully scabbed over, no new spots are appearing, and you are no longer infectious. This is typically around 5 to 7 days after the last new spot appears.
Because cabin crew cannot assess this at the gate, most airlines ask for a fit to fly certificate from a doctor confirming you are no longer contagious.
How many days after chickenpox can you fly?
There is no single fixed number, because airlines count from the last new spot rather than the first, and the rash can keep producing new spots for several days. As a general guide, most carriers ask you to wait until all spots have crusted over, which is usually around 5 to 7 days after the final spot appears. British Airways and Etihad commonly use a 6 day count, while easyJet, Jet2, Ryanair, TUI and Virgin Atlantic more often use 7 days. Always check your specific airline, and get a fit to fly certificate to confirm you are no longer infectious.
Can I fly if the spots have not fully scabbed over yet?
Usually not. Airlines require every lesion to be dry and crusted before travel, because unscabbed blisters mean the person may still be infectious. If your spots have not fully scabbed and your flight is close, contact us before ordering. Our doctors can review your evidence and advise whether a certificate can be issued, and if not, what wording your airline or insurer may accept in the meantime.
Does my child need their own chickenpox fit to fly certificate?
Yes. The certificate is issued for the specific person travelling, so each child who has had chickenpox needs their own certificate confirming their spots have scabbed over and they are no longer infectious. ZoomDoc issues certificates for both children and adults. You upload a short video showing the scabbed-over spots and complete the health questionnaire for each person travelling.
How quickly can I get a chickenpox fit to fly certificate?
ZoomDoc issues certificates with an average turnaround of around 1 hour during operating hours, 7 days a week. Upload a short video showing the scabbed-over spots and complete the health questionnaire, and your GMC-registered doctor will review it and send your digital PDF certificate by email the same day. If you have a flight within the next day or two, you can apply straight away without booking a GP appointment.
Will the airline definitely accept my certificate?
ZoomDoc certificates are signed by GMC-registered UK doctors, include the doctor's GMC registration number, and carry a QR code that airline staff can scan to verify authenticity. This meets the standard fit to fly requirements of most major airlines. Some carriers use their own specific medical form or wording. If yours does, contact us before ordering so our doctors can complete the correct form alongside the certificate.
Can I get a certificate if I have been exposed to chickenpox but have no symptoms?
A fit to fly certificate confirms your current medical status, so if you have been exposed but have no symptoms, a doctor can assess whether you are fit to travel. Be aware that some airlines apply restrictions to non-immune passengers who have recently been in close contact with chickenpox, because symptoms can still develop during the incubation period. Contact us with your travel dates and we will advise on the best option for your situation.
What is the difference between chickenpox and shingles for flying?
Both are caused by the same virus, and both are infectious while blisters are present and weeping. For flying, the same principle applies: you are generally considered fit to travel once the rash has fully crusted over and you are no longer contagious, with a doctor's letter confirming this. Shingles tends to take longer to scab than chickenpox. If you have shingles rather than chickenpox, tell us when you apply so the certificate uses the correct wording.
Do I need to tell my travel insurer about chickenpox?
Yes. If you or someone on your booking is diagnosed with chickenpox before travel, you should tell your insurer, because non-disclosure can invalidate a claim. If you are able to travel with a fit to fly certificate, that document supports your position. If you have to cancel because you are unfit to travel, you will usually need a separate letter stating you were unfit to fly, which is a different document to a fit to fly certificate.
My NHS GP will not provide a fit to fly letter. Can I use ZoomDoc instead?
Yes. NHS GPs are not obliged to provide fit to fly letters, and many decline or cannot see you quickly enough before travel. ZoomDoc's GMC-registered doctors issue chickenpox fit to fly certificates entirely online, with no appointment and no waiting room. The process takes minutes to start and your certificate is typically issued within around 1 hour.
Can I apply from outside the UK or while already abroad?
Yes. The whole process is online, so you can apply from anywhere in the world. You upload a short video showing the scabbed-over spots and complete the questionnaire, and your digital certificate is emailed to you. You do not need to be in the UK to apply.
What information do I need to provide?
You provide the name and date of birth of the person travelling, a short video clearly showing the spots have scabbed over, and answers to a short health questionnaire covering when the rash started and whether any new spots are still appearing. If your airline has given you a specific form or wording, upload that too so the doctor can address it.
