Flew Hainan on a BKK-PEK-BOS airfare deal/mistake a few months back.

Top quality product (ok, not Emirates, but still better than AC/LH/UA in my book). Wonderful 787, clean, didn't mesure the seat length but it was more of a straight/full width bed, not a pod with a cubbie to smash your feet into.

Scored my first pair of airline Pajamas thanks to this flight as well.

I also don't recall if their 787 J cabin had a bidet in the bathroom. ANA's that I flew on last weekend did!!

7hr PEK layover included a free hotel room (Hilton), limo service which I used from Tianamen Square back to PEK, and another limo from BOS to my destination. They wanted to give each connecting pax their own hotel room, and their own private limo.. Even though a few were families traveling together.
