I will soon be taking a long haul flight (~7 hrs) at 27 weeks pregnant (business trip from UK to Canada). I am flying premium economy and have an aisle seat, so will have a reasonable amount of space and will get up and down frequently to move around. Does anyone have any particular tips on how to make the travelling more comfortable at this stage in pregnancy? My midwife doesn't have any concerns re: DVT so I am not planning to wear compression stockings. TIA!
