Spirit And American Airlines Delays Extend To Fourth Day

HOUSTON, TEXAS - AUGUST 05: People check in for departure flights at the George Bush Intercontinental Airport on August 05, 2021 in Houston, Texas. Spirit Airlines and American Airlines have been forced to cancel hundreds of flights in recent days as the demand for vacation and other travel plans has surged following the ramp up of Covid-19 vaccinations. Some of the cancellations come amid a weekend of storms that affected hubs for both carriers, but also a shortage of flight crews due to the ramp up in service is having an effect.
