I was looking for award tickets on some of MU's staple regional routes yesterday and noticed that Delta doesn't show any MU results. Then I tried some intra-China routes where I know there is almost always award inventory on offer (e.g. SHA-PEK, SHA-KMG; never waste mile on these btw)...also nothing on MU, but tons of options on CZ, which is leaving Skyteam. Isn't MU one of DL's core partners? This isn't a huge deal for me, but it would be nice to be able to use miles between Shanghai and Japan without having to stop in Korea. Maybe we need to book by phone? Thanks in advance for your insights.
