Another day of problems for passengers flying Spirit as the airline cancels hundreds more flights because of ongoing issues with its computers, staffing shortages, and weather. It’s the fourth day of major flight cancellations. In a statement Spirit is apologizing today saying it is working to completely reboot its system by getting planes and crews where they need to be to start fresh on Thursday. Spirit is hoping to see cancellations come way down tomorrow but in the meantime passengers remain stranded in cities. Most have, though, now been given hotel vouchers so they are not sleeping at the airport anymore.
