I'm not sure where the market efficiency will lead us in this case. I personally am happy to pay ~20% more to fly with a non-US carrier. However, they are making that really hard. First off availability is an issue. How many different fights leave from SFO to Tokyo Haneda (I don't like Narita) on a Friday morning? Then you have these alliances where you book one airline and it gets swapped out for a different carrier. I've in the past booked a particular flight because it was operated by Air Canada and they switched it to United(?). We were flying via Canada to avoid this and still it happened. The market is not as perfect as buying soda off a shelf. I believe that if it was ahs foreign carriers were showed domestically US carriers might be in big trouble. But maybe I underestimate how much price matters to most people.
