Frontier Airlines Announcement:
During the early morning hours of Saturday, March 7, Frontier Airlines will transition its reservation and airport check-in system to a new model, and as a result, Frontier reports there will be a system outage during the overnight hours of March 6 and 7 estimated to take place from 10 p.m. – 2 a.m. MT as they make the switch.
Due to the switchover, Frontier’s normal check-in times need to be modified on Friday, March 6. Instead of allowing customers the usual 24-hour window prior to flight, check-in will be limited to a six-hour advance check-in between the hours of 4 a.m. and 9:30 p.m. MT. Web and kiosk check-in will then be disabled at 9:30 p.m. MT at which time a message will appear on the home page indicating the temporary outage.
Frontier requests that customers arrive early to check-in. Most Frontier ticket counters will be open 3 hours prior to scheduled departure time. In the following cities the ticket counter will open 2 hours prior to departure: Atlanta, Cleveland, Indianapolis, Miami, Milwaukee, Orlando, Philadelphia and Trenton. Early check-in will help the airline make a timely departure. Please note that the check-in process could take longer than usual.
Frontier also reports that its system will be down for a short period on Saturday night, March 7 from 9 p.m. to midnight MT.
For customers needing assistance, please visit the Frontier ticket counter.
Thank you.
