Qantas Airways' (ASX:QAN) "Project Sunrise," which envisages planned 22-hour non-stop flights from Australia's east coast to London and New York, was delayed after airplane manufacturer Airbus said the modified A350 aircrafts required for the journey were delayed due to supply chain issues, according to multiple media reports on Monday.

The airline is now expected to take delivery of the new planes in April 2027.

Qantas indicated it expects to have five such ultra long range aircrafts by November 2027, The Sydney Morning Herald reported.

Qantas ordered 12 of the specially equipped A350s in May 2022. The first plane was originally to be delivered to the airline by the end of 2026.

Qantas' shares soared 5% in recent Monday trade.
