My girlfriend's dad is a Metrojet pilot. He is pretty happy with them, and that should say something about the airline in general.
I like the 737-200s. They are old, that's true, but there is a lot less technology in an old plane. And for me, that's something nice to get away from once in awhile. I mean, the plane flies just fine, so it's nice to have just engines and hydraulics for a change, rather than three mega computers all making decisions that might agree, might not.
Sure, the electronics DO make them safer and far more economical, but give me a 727 or a 732 or a DC-9 any day, I'll be perfectly happy.
And it's a proven plane. We know how good the 737 is, and the first generation is what set the ball rolling. Look how many airlines still operate 732s- USMetro, Delta, United, Southwest, and probably others. Vanguard too. But they're not really a major.
