Frontier was the launch customer of the Airbus A318; between 2003 and 2007, the airline took delivery of eleven of the type. Retirement of the type began in 2010 and was completed by autumn 2013. All of Frontier's A318s were parted out for [[scrap]]. At the time, the five youngest examples had spent less than two and a half years in active service, while the oldest two were just over ten years old.{{Citation needed|date=September 2024}}
