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.
It is only recently I have a noticest something. Previously when I have been travelling with a companion, I always ended up sitting separately. Luckily, as a regular solo traveller, I have never been tempted to upgrade to seats together. I can handle a 3 hour flight alone, but others might not be like me. Imagine how much money Ryanair collects each flight.
