It's all about cost. They're the only large airline that knows how to keep costs under control and it costs more to fly international. I'm sure they're also looking at whether it fits into their business plan of short turns. Those markets are notoriously low yield as well. I wouldn't complain about a management that has managed to keep debt to a microscopic level especially when I look around at others (mine included) that have door busting debt coming due. When the cost benefit analysis shows it makes sense I'm sure they'll do it.
