Ryanair. Good.
I've flwon about 30 flights with Ryanair. Most flights are 1-2 hours because Europe is tiny. I like to think of Europe as another state, kind of like Texas. They don't like that I consider them a US state.
Back on point: Ryanair seats are plastic pieces of crap. Some of the flight attendants are only moderately attractive. The airports they use are usually like an hour or two drive from the city they supposedly fly to. So add on another $15 each way for bus tranportation to and from the airport.
Flights have cost me anywhere from $1 to $150. Time is crititcal. Book in advance. If you book late, they will severely punish you with fees.
I showed up 3 minutes late once. The check-in gate was closed, and I had to buy a new ticket. They are strict. Be on-time. Rules are very specific and you better adhere or buy a new ticket.
Flights takeoff on time and usually land early. I've landed late only once or twice.
They never lose bags. All flights are point to point. No transfers.
All in all, Ryanair is awesome. I wish we had something like that in the states. I almost bought a ticket last month to fly to a different state...the cost would have been around $700. I couldn't do it, not after flying Ryanair internationally for $20 a flight. US airlines suck.
Yeah you get a crappy seat, have to be on time (well check-in is 30-35 minutes before takeoff, so that's not so bad at all), and fly into weird airports outside of the city, but the cost is sooo low that it is totally worth it to me.
We're talking about one hour on the flight, and an hour on a bus. You usually can spread out on the bus. That's worth the savings.
