When travelling on long plane rides, I usually recommend that you don't sit idle for long periods of time when pregnant. You don't sit for a five hour flight if you're pregnant, you have to get up probably every one to two hours and move around. Because in non-pregnant states there is an increased risk of developing blood clots, and obviously in a pregnant state that increases. And so, when you're pregnant you need to move around when you are on car rides or long airplane trips so you can decrease the risk of developing a blood clot.
