DENVER (AP) — Frontier Airlines has canceled more than 50 flights through Saturday because of a hailstorm in Denver that knocked nearly a third of its large planes out of service.

The airline says 18 of its 59 Airbus planes and two turbo-props were damaged in the storm that hit Denver International Airport on Wednesday. Five of the Airbuses could be returned to service this weekend, but the rest could take longer to repair.

Frontier is waiving rescheduling fees for those affected.

The airline also says it's trying to book passengers on other airlines and get more aircraft from its parent company, Republic Airlines. It's also paying for hotel rooms for stranded travelers.

Another top carrier in Denver, Southwest Airlines, had three planes damaged. With 550 planes, it didn't have to delay or cancel flights.
