There have been a lot of reports in the media about Ryanair splitting up passengers who do not pay for an upgrade. This is my recent experience.
I have flown Ryanair many times, and although I am ranting away about them, I will most likely fly with them again. Why? Because they are a budget airline and I am a budget traveller. I like cheap flights to great places. I love a great deal, and if you know how to handle them properly, Ryanair will give you just that . . .cheap flights.
