Shannon Airport has confirmed that a planned service by American Airlines from Shannon to Philadelphia will not now resume in May 2022 as planned.
The airline has confirmed that it has made a number of changes to its schedule for 2022 as a result of production hold ups by Boeing, which has delayed the delivery of its 787 Dreamliner large capacity jets.
The company has also cancelled planned services to Edinburgh, Hong Kong, Prague and Dubrovnik as a result of the delay.
Shannon Airport said it hopes to get the service back in 2023.
Aer Lingus has confirmed it will resume its transatlantic services to Boston and New York next year.
A spokesperson for Shannon Group said: "The aviation sector has taken a battering during the Covid-19 pandemic and recovery was always going to take time.
"Due to a shortage of aircraft as a result of delayed delivery of Boeing 787 aircraft, American Airlines have been forced to reduce a number of routes they operate worldwide.
"Among these is their Philadelphia to Shannon service. However, Shannon Airport is working with them on restoring this service for 2023.
"In the meantime, Shannon will see the welcome resumption of transatlantic services next year to New York and Boston with Aer Lingus, and to Newark with United."
