Flyglobespan has announced that it will scale back the number of flights it offers between Liverpool John Lennon Airport and New York JFK, less than a month after its launch.
The airline is blaming poor passenger numbers, but says it hopes to restore the daily service.
A Flyglobespan spokesperson said: "Unfortunately, load factors indicate that in the near future we will have to reduce the frequency to four or five times a week. We are currently working out the best way to implement this change to the service.
“At some time in the future, we would like to return to a daily service to New York from Liverpool but our experience would suggest that to make it viable we would have to introduce a secondary stop on the route, similar to our Liverpool John Lennon to JFK flights which fly via Knock in Ireland.”
Passengers on flights that have been cancelled will be offered the chance to fly on an alternative date or a full refund.
The Liverpool to New York service was launched officially at the end of last month by Yoko Ono, John Lennon's widow, and it was hoped that the new link would enhance the city's standing as European Capital of Culture in 2008.
