Memorial Day weekend is upon us, kicking off the busy summer vacation season, and airlines are forecasting that this could be their busiest summer ever. Industry projections indicate that despite relatively high airfares, U.S. airlines could carry a record number of passengers this summer, even though they’re still operating fewer flights than before the pandemic.

The coming months are likely to be a “stress test” for a national aviation system plagued by recent staffing shortages, antiquated technology, air traffic control problems, scheduling issues and labor disputes.

After widespread flight delays and cancellations last year, consumer advocates and some within the travel industry worry air travelers could face similar disruptions that will mess up their summer travel plans again.
