Europeans with adult stable jobs fly Ryanair and Easyjet because this is the best that they can afford on European salaries.
Nonsense. It's because they're sufficiently cheaper on certain routes, and when you're taking multiple trips a year, the price difference accumulates; and also because they have very good point to point service, so if you live in a non-hub for the national airline city - a Bordeaux, Lyon, Birmingham, Manchester, Edinburgh, Hamburg, Köln, Varna, etc, your flight options are a flight with a connection in the hub, or a direct flight with a low cost carrier to a destination.
I've never once seen people fighting or screaming on a cheap flight.
For long haul I have no problem going with better airlines (which still means European or Asian over US carriers every time...).
Not really. The difference isn't even that big compared to legacy European airlines these days. Ryanair doesn't do bottom barrel (eg €5) pricing anymore and the legacy airlines also charge for extras now like checked luggage and sometimes even carry on.
I just fly Ryanair when it's convenient due to time and routes. I honestly don't care which airline I'm on. In fact I like Ryanair because I can just buy the foods and comforts I want like priority boarding instead of having to get some pompous frequent flyer card from the legacy airlines.
I'm upper middle class and love taking friends / partners on trips. Always used Soirut without any shame as I do not believe much of what I see on social media tho before I flew Soorut all that negative crap pushed most likely by their competition had me worried about my first flight with them. After it made me realize oh all that crap on the Internet..a lot of it is made up trash like many things u see online and in the media. Don't trash something til u tired it and with Spirit anyone expecting the same service as on u get in pricey airlines isn't using their brain to define what an ultra low cost carrier is.
