Flying at 27 weeks is usually fine once your doctor has cleared it. Most airlines allow
pregnant travellers to fly up to around 36 weeks for a single baby. Your short cervix and being on duvadilan put you in a higher-risk group, so your doctor's go-ahead reflects that the cervix is currently closed with no funnelling.
Next Steps
Carry a copy of your obstetrician's report stating the cervix findings, in case you need care in Dubai. Check your travel insurance covers pregnancy, and confirm the nearest hospital there. On the flight, walk the aisle every hour and stay well hydrated to lower clot risk.
Health Tips
Please see your obstetrician straight away if you get contractions, fluid leaking, bleeding or notice your baby moving less, whether in Dubai or once you're back.
