Traveling during pregnancy

Julieann • FTM🌟Baby girl due 09.19.2018🎀👶🏼🍼

So I’m flying out to the West coast tomorrow (about a 4 hour plane ride and 6 day visit.) I’m prepared with a 1 liter water bottle to keep on me, comfy clothes, and tylenol for my migraines. I plan to walk the plane about every hour or so. Any other tips from those who have traveled pregnant? This will my first time doing it!
