Same experience as everyone else when flying Southwest and interCaribbean. BUT... you need to convince everyone in your group to do CARRY ON ONLY. If they do check and there is a delay in them getting their luggage off the carousel and up to the IC ticket counter they could be in trouble. The ticket counter outside security closes one hour before the flight... period. If you arrive after that you WILL NOT be able to check your luggage and WILL miss your flight. This happened to a group who was traveling on the same IC flight as us in January. One person in the group had to claim luggage and got to the ticket counter less than an hour before the flight. The people in the group who had carry on only and were at the gate tried to convince the IC personnel to get someone to check their friends luggage at the ticket counter but to no avail. Best they could offer was a seat on the next flight, for which there was only one left.
