Megan, don't wish too hard for a Ryanair or Easyjet airline! Of the 2, Easyjet (or easyjet as it prefers to be called) is slightly less irritating, but both charge extra for every single thing that you probably take for granted. Pay by credit card? That's extra. Debit card? That's extra, too. Baggage? Oh dear, we'll have to charge you more for that. Want to select your seat? That's a No, we prefer to herd you onboard. In flight meals? You'll need to take out a mortgage, but don't even THINK about bringing your own food.
Ryanair is the Big Baddy because it seems to go out of its way to make passengers feel unwanted. It is trying to bring in a charge to use the toilets in flight now!
Both airlines operate a 'marketing philosophy' for ticket prices. They are entirely flexible, based on an almost real time analysis of demand. The result is that, whenever you want to fly, expect to pay a lot more than the person sitting next to you - who actually wanted to fly at a different time but found the fare too expensive!
Thus a fare advertised at, say, $29 will actually work out at over $100 - and expect your return flight to be $250 or more to get back home!
