Hawaiian Airlines, which cut summer flying due to delays by Airbus in delivery of A321neos, still does not know when it will receive its next aircraft from Airbus.

"We are still waiting for specific information about when our deliveries will resume," chief executive Peter Ingram tells FlightGlobal. "It's still a very fluid situation."

Airbus last month announced that it had halted delivery of A320neos powered by Pratt & Whitney PW1100G engines after discovering problems related to the engines' knife edge seal. The problems stemmed from an engineering change that P&W made to the engines in mid-2017. That change was aimed at improving durability, but some of the modified engines suffered failures.

Airbus has said deliveries could be suspended until April. P&W has developed a fix for the problem and intends to resume deliveries of PW1100Gs to Airbus in early March, it has said.

The delays forced Hawaiian to drop its plans to operate A321neos this summer on the San Francisco-Honolulu and Oakland-Kona flights. Hawaiian also postponed its planned Oakland-Lihue flight.

"We are obviously frustrated that we have delays right now," Ingram says. "We are actively communicating with the airframe and engine manufacturing."

Hawaiian has received two A321neos, and has outstanding orders for another 14 of the aircraft, according to a securities filings.
