I swear, some of you guys must not have ever flown on these non-US airlines. You guys make them sound like utopia, but I'm here to tell you, they're not!
Here's how I'd rank foreign carriers I've flown on, often in business class, compared to US airlines:
Bulgaria Air: Awful. Cramped and dirty. Rude flight attendants who scoffed when I spoke English.
Kuwait Airways: Hahaha. No.
Ethiopian: Don't touch anything.
Alitalia: Absolutely not.
Aer Lingus: Good if you enjoy paying €2 for a soda intra-Europe. Long-haul, on-par.
British Airways: Inferior intra-Europe. On-par in long-haul.
Lufthansa: Inferior intra-Europe. On-par in long-haul.
Emirates: Superior.
Singapore: Superior.
Oman Air: Superior.
Korean: On-par intra-Asia. Long-haul, somewhat superior (though I was business class on an A380, so that might be skewed).
Asiana: On-par.
China Airlines: On-par.
JAL: On-par.
ANA: On-par.
Oh, and I just flew with a guy who got out of a Turkish business class seat hating life, but that's second-hand.
My point is, you all would be surprised at just how bad these foreign, state-run airlines can be. One of the things that annoys me on JC is the constant "Everyone outside the US does it better," about well, just about everything. It's not true. Trust me. I'd take a US carrier over many, many foreign carriers, and that comes from personal experience.
