Is it save to travel on flight on 11 weeks... travelling hours will be 1.30 minutes..??

Do confirm with your doctor first, before flying. Travel isn’t recommended for those with high-risk pregnancy conditions like hypertension, sickle-cell disease, heart disease, history of premature labour and placental abnormalities such as placenta previa, etc. If you travel, try to book an aisle seat for faster access to the toilets. Also, if you have nausea and vomiting now, ask your doctor about safe anti-nausea medication to take with you, just in case. Don't drink or eat gassy stuff like fizzy drinks before or during your flight.
