Sat in Rockford airport that ended up being a 7 hour delay, never received a notification about the first delay, when we finally took off 7 hours later and arrived at our destination at 3:00am obviously car rentals were closed( had a reservation for a car), there was supposed to be an Allegiant rep on hand upon deplaning to help with transportation- there was no one. We incurred $260.00 in expenses in the first 5 hrs of landing, absolutely NO attempt from Allegiant to rectify the situation before taking off
