While "dodgy" isn't a word I'd use to describe MU, they are still second worst in my book. I have no complaints about their service in the air, but their ground ops suck. In particular, they run an ambitious schedule between PEK and SHA (basically hourly), but on MANY occasions, I've arrived at the airport to find my 5p flight merged with the 6p flight. The other carriers do this too, of course, but when flying MU, I've found that info regarding such matters never reaches the check-in counter. So, I've learned to avoid holding MU tickets when time is of the essence. Even an HU ticket is better because when they cancel flights, they tend to be upfront about it.
