Got the combo. The carry on came inside the check in. I've been using the (orange) carry on once a month for over a year and I love it. Compact vented and easy to open and find everything. The water resistance is a nice thing in case I go on a trip and my luggage seats out at all. Didn't have any issues flying southwest. Used the backpack and carry on and didn't have any issues worked perfect for my trip. Didn't need to pick up luggage or anything.
