Thanks James for the welcome!
You're right Prestwick is a bit of work in progress but Girona isn't the biggest of airports and probably not that clean either,nevertheless Ryanair is still expanding to 9 aircrafts there.
I'm glad you,and maybe others,also noticed the recent lack of expansion by Ryanair on Prestwick,meaning that something has changed in that partnership.
Even for easy targets,such as summer flights to holiday resorts that signed the famous "subsidy" contracts,thus entitled to be connected with somewhere,Ryanair preferred to use other UK bases or even Stockholm.
Who has some information on this?
