Ryanair, Europe’s leading low cost airline, said on Wednesday, that it had suspended taking bookings from November 12 for flights to and from Brussels-Charleroi, one of its network of operating bases in continental Europe, in a growing dispute with the airport.

It said that “a number of issues” remained outstanding in the wake of a wildcat strike by security staff, which closed the airport over the weekend of June 15-17 forcing the cancellation of flights affecting more than 22,500 of its passengers.
