The complement is joined by a selection of other Ryanair staff, all similarly attired in flesh-flashing bikini tops and bottoms.

The images are a long way from Ryanair's usual uniform, demure buttoned-up blue suits and high neck blouses.

And though the girls are probably guaranteed to get flight-deck temparatures soaring, some might say they are not the best advert for children's charity Angels Quest, which will receive proceeds from the calendar.

"Passengers will be able to bring a dozen of Europe's most stunning cabin crew home for just £5.

"This exclusive Ryanair charity calendar will be on board for a limited period only - so we urge passengers to buy the next time they fly."

The Girls of Ryanair Calendar 2008 will be available on board all flights from Saturday November 17, with money going to Angels Quest, which provides respite care for special needs children.
