Hi @lcastro1298,
You can check your bag with the dolly attached, but it is larger than our baggage guidelines allow for, there might be an oversize charge. Also, it will probably be conditionally accepted (meaning Southwest does not accept responsibility for damage) because it is an irregular object. You can check with the Ticket Agent to see if they thing it meets the standards for a carryon bag. If it folds up small enough, you could probably put it in the overhead bin.
