Let's stop that one in its tracks......
Whatever you may think of Ryanair's commercial policies, commercial dishonesty, awful passenger contact staff and dreadful customer service, its maintenance is second to none.
Paradoxically, this is part of the same piece; Ryanair recognises that maintenance downtime is expensive, and unscheduled maintenance, diversions due to technical problems and technical delays are the most expensive form of maintenance downtime.
Therefore the airline's policy is that all that will be prevented by running the most efficient and high-quality maintenance possible.
It works. Look at the records.
