Carry-On Summary

Southwest allows one piece of carry-on baggage, with maximum size 10 x 16 x 24 inches, but does not specify a weight limit. As long as you're able to fit your carry-on into the measurement bins by the check-in desk, you should be fine, as it'll fit under the seat in front of you.

You are also entitled to bring one "Personal Item", such as a purse, briefcase, or camera bag. Again, it must be able to fit into the overhead compartment or below the seat in front of you.
