As SLF I am appalled by the apparently inevitable lowering of standards likely to be the outcome of Ryanair plugging gaps in the pilot numbers.
I can just force myself to use that airline when my desired flights cannot be met by alternative providers [a recent trip to Salzburg for example] but hitherto my objections to Ryanair have been on comfort in flight.
Hitherto I have felt safe in the air.
Should I worry in future? There can be little more hazardous than very tired and very unsettled pilots.
