Ryanair is offering passengers the chance to have a flutter before flying as it teams up with a web bingo group.The budget airline said travellers can play bingo while booking their flights, car hire, and hotels on its website www.ryanair.com following a deal with jackpotjoy.com.The low-cost carrier offers services such as insurance, hotel bookings and car hire which boosts revenue for the group.In the year to the end of March 2006, these services generated €259.2 million (£173.2m) in turnover - 15.3 per cent of Ryanair's total revenues of €1.69 billion (£1.2bn).In June, the airline said it expects ancillary revenues to grow at a faster rate than ticket sales in the current business year.Ryanair recently teamed up with communications company OnAir to fit its aircraft with technology which will enable passengers to use their mobile phones onboard for a fee.
