Safe to fly while 7 weeks pregnant?

Hi! So my husband and I are going on our honeymoon, which was obviously booked way before we got pregnant with our wedding baby, which is our first baby. The flight is non refundable... will it be safe to fly an 8 hour flight to Hawaii? When we come back I'll be 8 weeks pregnant and it will be a 10 hour flight, but will have a layover... is that safe?

I know everyone says ask your doctor... well I'm starting new care at a new hospital and they wont see me until I'm 8 weeks... which my first appointment is after Hawaii... so I cant really ask my doctor because I dont have one...
