Southwest, Booster Seats and Carry-on?

[Kes]

My daughter and I are flying down to WDW tomorrow on Southwest. I really want to bring her booster seat for the car even though she's technically allowed to ride in a car without it down in Florida. My question is, can you gate check a booster seat the way you can a stroller? I don't want to check it in as we're only taking carry-ons - my other luggage went down with my husband today.

Also, if you have a boarding pass already (I'm going to do online check-in) and you only have carry-ons, do you need to check in anywhere at the airport (like at the gate) or do you just go to the gate and board the plane?

Thanks

Yes you can gate check the car seat. No need to stop anywhere but security if you already have your boarding pass and carry ons.
