Tried to check in online at exactly T-24 and am getting this message for myself and my CP holder:
Airport check-in required.
Your itinerary is ineligible for check in online. Please proceed to a Southwest® ticket counter to check in for your flight
Really not looked forward to end of C boarding on a packed flight.
Data for me and my companion were autocompleted, so I don't think it would be Secure Flight issues.
Our flight to ATL has not been cancelled, but the next segment under that flight number to Fla has been cancelled, so I wonder if that could possibly be the problem. Hopefully our flight is not in the process of being cancelled.
Any suggestions?
