We booked two roundtrips between Hawaii islands via the Hawaiian Airlines website. As other airline companies, HA provides multi-language website pages. In China, the official website automatically turns to www.hawaiianairlines.com.cn. However, for the same itinerary, the US and China websites show hugely different prices at the SAME TIME. For the roundtrips between HNL and ITO we booked, in China we paid about US$780 for 4 passengers, but if we booked through US website only $576 needed. Those prices were checked at the same time.
I traveled a lot via different airlines, but I never found such a large price difference provided by one Airlines for different language speakers. It's racist. Also at HA China website there is even no review and confirm processes before charging your credit card. I am really disappointed with this booking experience.
