Living in Europe, I swore off virtually all low-cost carriers more than a year ago. The idea of a €20 round-trip to London is all well and good, but not only is the flight experience absolutely terrible, when I learned how low-cost carriers treat pilots (e.g. pay-to-fly, requiring pilots to pay for their own cert. renewals, etc.), my new-found inner Euro-commie took over and I said I'm done. I agree with Jeff that it'd be awesome if we had only the best of the best pilot planes, but I don't even need that much, I just want someone who knows what the hell he or she is doing, and whom the industry has vetted for "issues" (both professional and personal).
