Mexico City - The Mexican low-cost Volaris has delayed the deliveries of five A320neo that are due in 2018 and rescheduled the deliveries of some initially intended for 2019.

Volaris was one of the airlines hit by the February grounding of A320neos equipped with Pratt & Whitney PW1100 engines due to the problem concerning the knife edge seal explicitly in the High-Pressure Compressor (HPC). Volaris grounded only one A320neo at the time.

Volaris was one of the first to incorporate A320neo in our fleet, and as a result, we have been experiencing maturity issues, leading to operational challenges. Volaris has, therefore, together with Pratt & Whitney and Airbus developed a more conservative approach to ensure the technology can deliver in line with our high operational standards,
CEO Enrique Beltranema said.

The Mexican low-cost carrier currently operates eight A320neo and two A321neo. The operator's third A321neo has already been deployed at Mexico City and will start serving designated routes in the coming weeks. Volaris has 74, A320neo and 33 A321neo in its order book.
