Ryanair is not just an airline - yes this is a core part of the business, but it is a brand
Ryanair is a brand with a negative value. By adding Ryanair to anything you know you will get ripped of in extra charges. A well-known chain of jewellers got to the point were the brand was a by word for cheap and nasty. With Ryanair needing to increase income it may not be cheap for too long.
The unthinkable is already happening in banking with big names going under. What will happen when Ryanair cannot pay for the next wave of new planes in a few years time?
