Yes, a 7-month pregnant woman (approximately 28 to 31 weeks) can generally fly with UK-based airlines, but there are specific medical requirements to follow. Most UK carriers, including British Airways and easyJet, allow women with uncomplicated single pregnancies to fly up until the end of the 36th week, or the 32nd week for multiple pregnancies (twins/triplets). However, once you reach the 28th week, almost all airlines require a "Fit to Fly" letter from a doctor or midwife. This letter must confirm the expected due date and that the pregnancy is progressing normally with no complications. In 2026, it is highly recommended to carry your maternity notes and ensure your travel insurance specifically covers pregnancy-related events. "Pro-tips" for flying at 7 months include wearing compression stockings to prevent deep vein thrombosis (DVT), staying hydrated, and choosing an aisle seat to allow for frequent walks to maintain circulation during the flight.
