Timothy - I thought I'd head off any potential confusion over the 67 Guangzhou airport buses.
There are actually two bus operators for the Guangzhou airport - together they total 133 buses. I asked wctbills to clarify that he is only talking about one of the two, but he hasn't yet for some reason.
Incidentally, I have "explicitly made this kind of confirmation" for every CCME airport contract. I've got names, numbers and websites as well as confirmed the CCME contract, number of buses and passenger volume. Most wouldn't comment on the particulars of their contract with CCME.
Unfortunately, the bus operators don't post this information on their websites so you'd have to call and ask the right kinds of questions in Chinese to get them to tell you this info. I haven't posted the operator's contact information because I wouldn't want a hoard of short-sellers calling and bugging them - but their contact info is easy enough to find.
