Thanks for the heads up. If I end up flying one of the KA 32M birds, I'll report back too. In the meantime, I'll try to secure either a $25 paid or OWE upgrade into the certain extra legroom exit row 33 on those planes.
Luckily I was able to move my AUH-HKG-HAK flights up from Fri to Thu so the Thu HKG-HAK flight is a A321 with the 24 J seats. Dodged a bullet!
