hello T.,
i've recently taken my 2 1/2 year old son on an airplane ride last month to las vegas. you don't really need to bring a car seat, unless you feel safer with him in there. honestly, if you bring that it will just be more stuff to bring on the flight, unless you have on of those car seats that convert into a stroller too! he was perfectly fine in the middle of my husband and i, but he enjoyed the window seat more! hahaha my suggestion is to bring something that your son really loves, like a favorit stuffed animal, or just something to keep him occupied for the plane ride, like a lollie pop or crackers, and also make sure you bring his fav drink, but make sure it falls in the airport policies, you know how striked they are these days! also, at the time my son was still on a bottle, he isn't anymore, but sucking on the bottle helped his ears not get plugged, maybe try a sippy cup, the non spillable ones, because she would still have to suck on that. Good thing you are going with your husband because the very first time i brought my son on an airplane ride i was by myself and he was about 1 1/2, that was horrible, and never again will i do that...haha...anyways, good luck with you and have fun on your vacation. hope this helped!
