Ryanair has suspended its onboard mobile phone calls system after its provider cancelled the contract.

According to reports the airline and OnAir have not managed to agree an expansion plan for the service which launched last year on 50 aircraft.

Ryanair had hoped to roll the system out to its 230 craft fleet but a spokesman said OnAir had been unwilling to commit. Calls cost £1.50 a minute and 40p per text.

Ryanair said it was now looking for a new system for what chief executive Michael O’Leary has described as an important revenue stream of the future.

OnAir chief executive Benoit Debains expressed regret that an agreement could not be reached but said the company, which already works with airlines such as British Airways, Air Asia and bmi will shortly be announcing new agreements with other short and long-haul carriers.
