You should speak with your travel company or airline. Normally, you can’t fly if you’re more than 32 weeks pregnant at the time of your return flight, do not book your flight before checking the airline’s policy.
We recommend that if you’re flying after 24 weeks of becoming pregnant you take a letter from your doctor confirming that it’s safe for you to travel. This letter should not be dated more than 14 days prior to the initial flight.
If medical advice is that you should not travel, you should contact your insurance company to submit a claim. Always let the insurance company know about your pregnancy at the time of taking out the policy or if you subsequently fall pregnant.
If you are travelling to a part of the world where the Zika virus is prevalent medical advice is not to travel there, check on the Foreign and Commonwealth office travel advice before booking or after you fall pregnant.
Talk to your doctor who can advise whether you should continue with your plans.
If you do continue your holiday, check that your travel insurance covers you completely.
