Booking
2 economy one-way Fortune Flex award tickets booked online at hnair.com, the Chinese website, for 10,000 points + 100 RMB each. The cash price was about $110. The English website hainanairlines.com does not appear to have the award search page. Google translate is your friend. You may choose fare classes and extra luggage for more points. Fortune Classic awards are a fixed award chart, Fortune Flex awards are dynamic (?) based on cash price. The catch is when you redeem, credit cards do not appear to be an option for payment - must use something like WeChat or Alipay QR codes. I felt safe when I had ticket numbers in hand. Booked at about T-50 days out. Fortune Flex awards did not appear when I was looking at 90+ days. Note that you must register other people you want to use points for two months before the month you want to use them. Registration in May leads to only being redeem for them in July. I wasn't able to manage the flight online, but emails to the vip@ email (for status holders) to assign seats were answered within an hour.

Check-in and Lounge
With my Fortune Wings Gold status (earned from the Hong Kong airlines mistake fare in 2019 that somehow was extended 5 years, along with 6 unused upgrade coupons), I was informed I had a 70kg allowance, and successfully checked in 4 checked bags. I also received 2 lounge coupons for the VIP 190 lounge (for me and my companion) - very handy as my Priority Pass only has 2 guest allowance. Lounge dragon only submitted one guest when I gave him my PP card and the two lounge coupons for 4 people. Lounge is very underwhelming, just a room with armchairs and an underwhelming buffet of two tasteless vegetarian bao options when I entered. Around 5:30 they changed the buffet to real food like fried rice and chicken. The highlight of that lounge are the noodles - instant noodle cups and a person to make fresh bowls with spicy meat.

Flight
Boarding was simply everyone lining up in a double file line. No group announcements or anything. I could probably have cut everyone with my status but didn't bother. I traded seats with one of my companions on a separate reservation, but I was told that the flight attendant greeted my companion, recognized my status, and prioritized their requests. The seat was an average tight economy seat on a 737, nothing remarkable. Like most longer Chinese domestic flights, we received a box of economy food - rice, chicken, some glutenous dessert, yogurt. I ate little of it as it tasted bad and I was full from the lounge. No power outlets anywhere. Remarkably, the priority baggage tags were effective and my bags were the first off the carousel.

Overall, economy/10 flight. Extra baggage allowance, priority baggage, and lounge coupons saved me some money. Best of all, my point expiration date has been pushed another 2 years out. Maybe I'll use them to book Alaska domestic awards thru the vip email again, although the taxes were high-ish at around $50.
