The Ryanair boss said seated passengers would be charged £25 per ticket with standing customers paying between £1 and £5 for their fares on a flight that would take the average capacity of a flight from 189 passengers to 230. The proposal is the latest in a series of unrealised cost-cutting ruses that have earned the carrier free publicity and criticism from safety experts. O'Leary has claimed in the past that the carrier was looking at charging passengers for using the toilet, in a bid to limit loo facilities on planes and replace them with extra seats. Ryanair has also suggested it would put passengers in the hull – in bunks – and has called for flights with only one pilot instead of the usual two. Speaking at a press conference in London, O'Leary said he was undeterred by the knockback from the unnamed regulator, although he declined to comment on whether Ryanair had approached the US Federal Aviation Administration or the European Aviation Safety Agency. "I think ultimately it would happen," said O'Leary.
