Flying while pregnant?

I see my doctor on Friday and will be asking, but just curious on if anyone has any experience flying while pregnant. I haven't had any complications except a subchorionic bleed at 8 weeks that is now gone. It's a short (under 3 hour) flight. Going I will be 28 weeks and 3 days and coming home I will be 29 weeks and 5 days. I told hubby maybe not to book until I talked to doctor but he was too afraid prices would go up and did anyway.
