Your girls are beautiful!!!!
Good Luck flying with them. I flew with my boys twice from NH to NM to visit family. It went pretty good! I gave them 2 mls of children's benedryl to help them stay calm during the flight and the airport, it really helped. I just put some in an empty nip bottle so it was small enough to take with me on the plane just in case I needed to give more during the layover. I just with more airports had 'doggy areas' for them to get out and stretch their legs and pee. 8 hours of flying in a small crate is a LONG day for them.
