Monday morning and we were running a bit short on time due to unexpected traffic on the freeways. Thank goodness Terminal 4 saved the day! We were able to walk up to the kiosk at the Southwest ticket counter and check in our bags. Security only had about 6 people in front of us before getting to the ID check station. TSA was nice and knew exactly what to do with a baby and baby gear. Not sure if this is normal flow, but it was definitely a nice surprise with our time constraints.
