Why on earth would you do business with a company that makes you "<feel> cheated"? RyanAir ran off all of the other airlines? They had the only flight to Dublin to see your poor, sick mother? Flights so cheap that you're willing to put up with the bullshit? It's an honest question, and I've heard some answer it with "they're so cheap, I'm willing to put up with dealing with weasels." But it sounds like the whole weasel-dealing thing isn't for you.
One of the reasons I fly SouthWest, even when they're not the cheapest or most convenient, is because I don't feel like I need to watch my back when dealing with them.
Yes.
I've taken ~100 Ryanair flights. It's a bus service. Buses are crap too. Ryanair, like busses, are cheap.
Because everyone bitches about them but everyone still uses them, since after all, they are the cheapest. They just like to hurl rocks from the top of the mountain without actually doing anything productive about it - i.e. taking their money elsewhere.
When I booked flights to Dublin recently, I felt being cheated on even though I checked everything twice and googled some. The insurance trick is among the worst practices I had to encounter personally.
I'd prefer to have the official prices being hones even if they are somewhat higher. Their business model of offering only the minimal thing should work nevertheless and laws like that does not forbid them to offer extras which many people would choose nevertheless.
