A bus link that runs from the airport to a Leeds market town could be axed.
The 967 service, which runs between Leeds Bradford Airport and Otley, is under threat after the airport said it no longer wished to support the route.
Metro has said it will work up a new timetable to link Otley, Pool and Menston.
But local councillor Ryk Downes, who is also a board member for the West Yorkshire Integrated Transport Authority, expressed concerns at the proposals.
Coun Downes (Lib Dem, Otley and Yeadon) said: “The service was introduced as part of the airport’s responsibility to increase the number of passengers and employees accessing the airport via public transport.
“Withdrawal will mean that Otley residents will have to use cars or taxis to go on holiday.
“This is very bad for the environment and will increase traffic congestion in the area.
“I shall be asking council officers to pursue this matter with a view to retaining the whole Menston Station - Otley - Pool - Airport route.”
A report for a meeting of Metro’s Leeds Passenger Consultative Committee said that passenger numbers undertaking the journey between the airport and Otley were “very low”.
It added: “LBIA have indicated to Metro that from January 2013 they no longer wish to voluntarily support a link between the Airport and Otley.
“Passenger numbers undertaking this journey were very low so it would not be value for money for Metro to continue to subsidise this link.
“Metro is working up a new timetable linking Otley, Pool and Menston including the rail station.”
The report said that further details about the new timetable will be available later this year.
It is thought that the alterations will not affect 737, 747 and 757.
