Ryanair has once again warned it will reduce flights from City of Derry Airport if the controversial runway extension does not go ahead.
The low cost airline has only just reinstated its two flights a day service to London Stansted after axing one earlier this year.
But its deputy chief executive, Michael Crawley, has warned Ryanair will take the same action again if improvement works at the airport are not completed.
The threat comes just weeks after the airline announced even more new services from Derry to Liverpool and East Midlands which are set to take off in the spring.
Mr. Crawley was speaking to BBC Business and Industry Correspondent, Neil Gallacher, in an interview over Ryanair's threat to reduce flights from Newquay Airport in England.
It is opposed to the decision by the local airport's owners, Cornwall County Council, to introduce a new £5 departure tax which passengers must pay to take off.
The controversial levy has been brought in to ease its losses of more than £1million a year.
