DENVER -- Frontier Airlines has announced more flight cancellations through Tuesday after golf ball-sized hail at Denver International Airport took almost a third of its Airbus fleet out of service.

The Denver-based carrier said it had cancelled a total of 96 flights for Saturday, Sunday and Monday, on top of more than 100 flights that had been scheduled to leave Thursday and Friday.

Frontier spokesman Peter Kowalchuk said that they were working on a list of cancellations for Tuesday and Wednesday.

"We expect that we will see cancellations throughout the week, but not at the levels that we're seeing them now," said Kowalchuk.

The flight cancellations were scrambling Army soldier Vincent Rock's plans to see his family in Albuquerque before he ships out to South Korea.

"It's just a huge nightmare," said Rock, who had a cellphone pressed to his ear, as he waited at DIA on Sunday. "I've been trying to get a hold of Frontier Airlines since 11 o'clock this morning. It's now 3 p.m."

Kowalchuk said Frontier's call centers are being inundated, while mechanics work around the clock to repair hail-damaged planes.

Eighteen of the carrier's 59 Airbus planes plus two turboprops were battered by the hail storm Wednesday night.

The storm was part of a monsoon pattern that National Weather Service meteorologist Scott Entrekin told the Denver Post was weakening in the area but could still last another week.

It dealt Frontier a bigger setback than other airlines that use the Denver airport, leaving the carrier to enter short-term leases of other airlines' planes and make efforts to fly customers on other airlines or aircraft.

Five of Frontier's aircraft have returned to service, but the rest are still being repaired.

Denver's largest carrier, United Airlines, canceled 39 flights Friday, a day after it canceled about 90 flights because of hail damage. Twelve United planes -- out of its fleet of 710 -- were out of service as they were inspected for damage, but spokesman Mike Trevino didn't know the extent of the damage.

Another top operator at Denver's airport, Southwest Airlines, said three of its planes were damaged by hail, but, with 550 planes in its fleet, it didn't have to delay or cancel flights.

Frontier said earlier it was paying the hotel bills for passengers who've been stranded. Also, according to Frontier's website, fare differences and change fees were being waived for customers who rebooked by midnight, July 19.
