Travel with Children - Gate Check Both Car Seat and Snap N Go?

We are thinking of bringing a car seat (Chicco KeyFit) in a Snap N Go stroller for our upcoming trip on UA. Will they allow both to be gate checked or only one? I ask because the UA website says "When traveling with a child, you may check a car seat or stroller as your first or second bag free of charge", which if read strictly seems to suggest that you can only check on or the other without being charged.

I was never challenged on United with mine. I had another stroller frame. Also, try to score a seat on the plane since I'm assuming you're flying with a lap baby. If you can use it on board, then that issue is solved.

Thinking out loud, and I don't know the answer, if there are two parents travelling, and each separately checked one, would they even notice? Eg Mom boards with stroller, then dad boards towards end of boarding with baby and car seat?

I know the airlines' websites always say one or the other, but we have checked our twins' car seats and a double stroller plenty of times. Never had an issue.

Take that back. I was using the car seat on board (baby had a seat).

But honestly, when you're flying with a baby, often they give you a break. A Snap & Go is pretty minimal, as is an infant seat.

You have an "excuse". Tell them you're trying to use it on board.

Take two gate-tags at check-in.

Follow up--different but related question.

I'm travelling with a 2.5 year old who has his own seat. We'll need the car seat at our destination but not on the flight (we'll use the CARES instead, which he is more familiar with). Can we gatecheck the stroller and the carseat? I'll check the car seat as luggage if I have to but would prefer not to.

I've gate checked two car seats and stroller numerous times. No problems.

You can gate-check them on U.S. airlines. Some foreign companies wont, low-cost especially.

Since your child has a seat, tell them that you're using it on board, then there wont be a problem taking it to the gate. Ask them for a gate-tag "just in case" you have a problem.

If anyone insists you luggage-check your car seat, ask for a supervisor to be brought out.

If you bring your car seat to the door, it's much smarter to use it on board. Your child will be more comfortable, safer and more likely to sleep. The CARES harness is a good idea if you already have a car seat at your destination or don't need one but if you need your car seat, definitely using it on board is by far, the best way to go.

Gate-checking is better than luggage checking but no guarantee. Some airports use chutes that basically chuck the seat to the tarmac.

My primary concern is not that I'll be asked to luggage-check the car seat. It's that if I bring it to the gate, I'll be asked to use it in the plane. I specifically do not want to use it--I want to use CARES.
