I flew at 33 weeks with no issues. The airline staff didn't ask me any awkward questions or require extra paperwork or anything even though I was enormous by then.
An 8 week pregnancy won't be affected by air travel. Have fun!
I flew when I was 11weeks. They say not to fly in the third trimester or close to delivery. Ive never heard of it being risky before then
8 weeks shouldnt be a problem. Its when your in the 36 week area and could go into labor at any point. But i would talk to your doctor!
