Hello all,
I am trying to fly budget from Paris to Glasgow on July 21st. I looked at ryanair and easyjet. Ryanair is the only one to make that route for around $80. Heard bad things about ryanair. This the best way to go? Is there a list of budget airlines somewhere? I also have to get back to cologne on the 28th or 29th. Any help would be appreciated. Thanks
