flying in pregnancy, when should I stop?

[Luckyme30]

So due to covid-19 my holiday in May is likely to get cancelled - I would have been around 15 weeks pregnant so as far as I’m aware that would have been safe to fly.

I’ve heard that agents (I’m booked with TUI) are giving the option to re-book later on in the year has obviously that is only an option for me for a limited time.

When would you stop flying when pregnant?? Are there any rules on when I should and shouldn’t fly?

Also does anyone know if the EHIC covers maternity care, should anything happen whilst we’re away?

Different airlines have different policies, but c.v aside you have to get your midwife's permission to go after a certain time.
I went on holiday after a very uneventful pregnancy at about 27 weeks, ended up with food poisoning and then the first day I was able to go out I fell down a cobbled street, caused a huge infection in my leg. Due to the dates, I had to fly home on my own steam and go directly to hospital in the U.K where I was kept in with sepsis for 12 days. If I had been hospitalised in Portugal I wouldn't have been able to fly back because I would have been past the airlines cut off date.
That said, since DS has been born (he's 2 now) I've taken him to 11 different European countries, and it was certainly the easiest when he was tiny- toddlers need loads of stuff but tiddly ones only need hand luggage.
I suppose what I'm saying in a roundabout way is that it's a lot less risk once the baby is born- especially if you are breastfeeding because plane journeys are just one long feeding and sleeping session!
