It isn’t just with automobiles that the U.S. public sees American companies as worse than their overseas counterparts. Our airline industry also comes in for its share of lumps.

Anyone who has ever heard horrific air travel stories from colleagues, friends or relatives – and that’s most of us – wouldn’t be surprised if consumer ratings of U.S. airlines pale in comparison to others. And now we have the record to prove it. SeatGuru, TripAdvisor’s online site that bills itself as “the ultimate source for airplane seating, in-flight amenities and airline information,” has just released the results from its most recent annual survey of frequent fliers (defined as people who have flown at least eight times in the past year).

And what does this year’s survey tell us? For starters, U.S. air carriers have the least comfortable seats of all airlines.

Also, they serve the worst food – if they serve it at all.

Rude flight attendants? Bottoms again.

Who ranks best? If you’re looking for good food, the survey respondents tell us we can’t go wrong with Singapore Airlines, British Airways or Air France. Perhaps surprisingly, Continental Airlines also ranked well. But avoid American, United and U.S. Airways – rated the worst of the bunch.

These same three U.S. carriers also scored at the bottom of the heap for the comfort of their economy-class seating. JetBlue does score well in this category; too bad most of us never get the chance to fly this airline because they serve precious few cities. (For the best business class seating, respondents gave highest marks to British Airways.)

And guess what? The very same three carriers – American, United and U.S. Airways – topped the list for having the nastiest flight attendants. If polite, friendly service is your thing, you’re far more likely to find that over at Singapore Airlines or Southwest.

What about the all-important performance metric of on-time flight arrivals? For that, we can look to actual data compiled by the U.S. Department of Transportation’s Bureau of Transportation Statistics rather than rely on survey findings. What we see is that for the first three months of 2009, Hawaiian Airlines had the best on-time performance of any U.S. airline company, with more than 90% of its flights arriving within 15 minutes of schedule.

But they’re a small airline company. What about the biggest carriers? Southwest has performed the best, while Continental is at the opposite end of the scale.

And what flight to take if you want the dubious distinction of traveling the worst airline route of all? That would be Northwest Airlines Flight #5803 from Atlanta to Honolulu. It was late a mere 96% of the time. Well, there’s consistency for you at least!
