Hello, we will be travelling to Orlando via United in Feb. Has anyone ever checked a car seat and a booster with United? We will be travelling with our almost 4 year old and 6 year old. Our 6 year old is still in a 5 point harness here, but is big enough for a booster seat. Our almost 4 year old still needs a point a 5 point harness. I see that on United Website you are allowed to bring a car seat in addition to your checked baggage, but oversize rules apply.
Does anyone know if United considers a booster seat as the same thing as a car seat? As well, we measured our smallest car seat and we come up with 67 linear inches... oversize is anything over 62 inches. It would take a pretty small car seat to be under the 62 linear inch rule. Has anyone checked a car seat that is under the 62 inch rule? If it was over 62 inches, were you charged $100?
