Not so. Ryanair still are contracted to take 112 737-800 from Boeing during the next three years.
From their press release:
Ryanair, today (Fri 18th Dec 09) confirmed that its quarterly Board meeting yesterday determined that its negotiations with Boeing for an order of up to 200 new B737-800 series aircraft for delivery during the period 2013-2016 cannot be successfully concluded prior to the end of the calendar year and accordingly the Board of Ryanair have confirmed that its negotiations with Boeing have terminated unsuccessfully.
Ryanair confirmed that the breakdown of these negotiations will not effect its plans to take delivery of 112 B737-800 aircraft during the next 3 calendar years 2010 (48), 2011 (37) and 2012 (27), which will sustain Ryanair's strong traffic growth over the medium term. Ryanair will now bring forward plans to significantly reduce growth and capital expenditures, in order to maximise cash balances for distribution to shareholders during the period 2012-2015.
I'm sure it's all just posturing from MoL.
