KLM has suspended flights from Manston Airport to Amsterdam as a possible closure is considered for the Kent airport.
KLM Cityhopper services will stop on 10 April with concerns that it will not be able to guarantee the service if the airport closes, less than a year since the route started.
Passengers can be rebooked onto services from Heathrow.
Last week staff at Manston Airport were told a 45-day consultation process is under way about its possible closure.
Roger Gale, MP for Thanet North told the BBC he thinks the airport has a new ‘reputable’ buyer but did not want to ‘raise false hopes’.
The loss-making airport was bought for GBP1 by Ann Gloag (co-founder of the Stagecoach Group) in October.
