A recent article in China Daily pointed to charges that Hong Kong Airlines "has been accused of profiting from animal cruelty by striking a HK$850,000 deal to fly live dolphins from Japan to Vietnam."
Why were they headed to Vietnam? Because, Dolphin: it's what's for dinner.
Sandy McElhaney at Examiner.com (an open publishing platform, not a newspaper as the name may suggest) wrote this interesting post about the China Daily article, and a Change.org petition followed. There are a few scattered press reports, but they don't include much direct sourcing beyond the China Daily piece so far. Hong Kong airlines has issued a weak statement that denies responsibility for any wrongdoing, profiteering or animal abuse.
For what it's worth, China Daily is not exactly a free and independent press outlet, but known for more Western-style journalism than other state-owned papers in China.
