Oh you can keep the carrier in your lap!? That's great! It's only about an hour and a half flight. I probably wouldn't feed her that soon before seeing as though she is only 6 months and like only 98% potty trained i'd say.
I am flying delta which is still i think way over priced but agree it is worth it. How big is your baby? Mya is almost 8 lbs...I have a kwigy bo carrier but for that long of a trip I think she'd be cramped...it works for trips out to errands etc but I want her to be comfy with enough room.
I see a few online that I like but again, that will be adding another 100$ or so to the ticket price for her sigh. Children are expensive
