Just another in a long line of Ryanair PR stunts that haven't happened, including charging for toilets, long haul flights (with a business class cabin!) to name but two we've heard in the last year.

Although, Ryanair do tend to be the first to implement these sort of extreme cost cutting measures (at least amongst UK carriers), so if standing ever got off the ground I'm sure they'd be the first to do it... but given their track record, probably the time to give it credible discussion is when it actually happens.
