Ryanair don't need to base a shed load of aircraft at Leeds, remember they have 33 other bases, a few aircraft based will help them when it comes to winter and they can set off to Dublin rather than holding or diverting,
inbound by time the med based stuff is inbound the weather has normally improved. It will only be a matter of days before a Ryanair aircraft turns up with bye bye Jet2 and on pricing they will go for the jugular, they don't need to take all Jet2 traffic, they just need to make the flights (that Jet2) operate at a loss.
Its a cruel world dog it dog and all that but Ryanair have no choice they have too many aircraft coming into an over supplied market, something has to give and they have clout and cash
