additional fees at airport

[sseely40851]

Flying Southwest with Early-Bird check-in from Manchester, NH to MCO. Are there any additional fees I will be hit with at the airport (either way)?

The only extra fees would be for overweight luggage or for luggage over the free check-in limit. Also parking fees when you leave the airport (if you park there). Or tips if you do curbside check-in.
