Everything about the rescheduled (cost me $180) flight great. ***Being denied boarding because I was few minutes under 1.5 hours was not. Stuck at the Kiosk for about 15 minutes before it directed me to the Porter counter was strange. Do not know why checking in online at home was not successful? I think something was up...what can you do?
