Flying is not harmful to you or your baby, but discuss any health issues or pregnancy complications with your doctor before you fly.

The likelihood of going into labour is naturally higher after 37 weeks (around 32 weeks if you’re carrying twins), and some airlines will not let you fly towards the end of your pregnancy. Check with the airline for their policy on this.

After week 28 of pregnancy, the airline may ask for a letter from your doctor confirming your due date, and that you aren’t at risk of complications.

Long-distance travel (longer than five hours) carries a small risk of blood clots (deep vein thrombosis, or DVT). If you fly, drink plenty of water and move about regularly – every 30 minutes or so. You can buy a pair of graduated compression or support stockings from the pharmacy, which will help reduce leg swelling.
