Re: Taking a one year old on a plane??...crazy??
My DD is only 14 months old and has been on at least 4 flights (16 if you count connections and return flights) and I did it by myself all 4 times. She has almost always done great. You've have gotten great advice from other posters, but I would highly, highly recommend a carrier of some sort. I carried my DD in a sling and it allowed me to be hands free to carry a bag and her car seat on luggage wheels. That way I got her seat on most flights without having to pay for an extra seat. If the flight was crowded, they just gate checked it.
I even used her seat on the floor in the airport during the layover to feed her.
I agree that Southwest seemed pretty family-friendly.
I think you can do it, and its beat the long drive. BTDT won't do it again if we can help it.
BTW, where in AR are you moving? I'm in Central AR right outside of Little Rock.
