Qatar Airways passengers will have to wait a while longer before boarding an A320neo, the airline’s CEO has indicated.

Speaking at the Singapore Airshow this week, Akbar Al Baker said there is a “long way to go” in fixing the aircraft’s Pratt & Whitney engines and that he expects a “very huge” delay in receiving the planes, Bloomberg reported.

Al Baker added that Qatar Airways will seek compensation over the hold-up, which he previously said was having a “large financial impact” on the carrier as it works to address a capacity shortage.

However, speaking to Bloomberg this week, the CEO said that falling oil prices have prompted fewer people to travel, increasing the airline’s available capacity.
