Frontier Airlines is working to restore its scheduled service after a significant portion of its fleet was damaged in a hailstorm at its Devner hub on 13 July.
The carrier reported that 18 of its 59 Airbus aircraft were damaged as a result of the storm. Seven aircraft are back in service, including two aircraft that are scheduled to resume service on 19 July. Three aircraft are returning on 20 July, along with one each on 21 July, and the rest of the out of service aircraft on 22 July.
One spare A319 that experienced more damage, however, is not expected to return to service until the beginning of August, according to Frontier.
In the interim the carrier arranged charters "flown by Miami Air, Sun Country, North American, Allegiant and USA 3000" to help provide service while aircraft are being repaired.
Two Republic Bombardier Q400s that provide service for Frontier were also damaged, and are projected to return to service at the end of next week. Frontier also said that the flights operated by the damaged Q400s are being covered by Embraer E-170 aircraft that are part of the Republic Airways Holdings fleet.
The storm also impacted other airlines with large operations in Denver, but to a lesser degree.
Three Southwest Airlines aircraft sustained damage in the storm, but a spokesman explained to Air Transport Intelligence that no cancellations or delays resulted due to aircraft swaps. All three 737s have since returned to service.
A United Airlines spokesman, meanwhile, said that "about a dozen aircraft were taken out of service for inspection" while "less than ten" remain out of service.
