BBC NEWS | Business | Ryanair closing Manchester routes
Ryanair is to switch or close nine of the 10 routes it currently operates from Manchester Airport, blaming the airport's refusal to lower its charges.
......Ryanair said it had offered Manchester an additional 28 weekly flights if the airport agreed to reduce its charges, but that it had rejected the offer.
Ryanair also said that if Esso would only charge them half the price it charges everyone else for fuel, then Ryanair would be able to increase flights, and it was only the oil company's intransigence that prevented this.
They further commented that Boeing ought to charge them half the price they charge everyone else for 737s.
