I respect your perspective, E, but it doesn't matter whether AA or US employees or fans are the dominant participants on this forum.
you made the statement that Asian customers expect to be able to buy their alcohol and tobacco.
DL doesn't care what any customers want if DL can't justify that they make money providing that product or service.
You worked for AA by your own statements on this forum.
There have been endless discussions about services or routes that AA has operated that do not make money or which people complain about AA cutting despite no evidence that those decisions will financially hurt AA or not.
I have made plenty of factual and positive observations about AA as well.
IN this case, it is absolutely relevant that DL will not provide a service that it cannot make money providing even if customers want it while other carriers and their fans/supporters on this website have talked about how AA needs to be willing to invest in products or markets knowing full well that they will lose money providing that service or product.
While I, like you, said that I wanted AA to remain a standalone airline and rebuild, it is clear that Parker and co. are making changes at AA based on their expectations and experience regarding delivering financial results first.
As with any other decision that should be made by a profit-oriented company, including your comment about customer expectations about buying certain duty free products, the goal is ALWAYS to be profitable and if profits can't be shown (even internally) then mgmt. better be able to justify why they are choosing to do something unprofitably.
THAT is the essence of why there was a mention of any other carrier in this thread.
