I was about to book a Biz class one way on Cathay from BKK to HND. Upon my suprised, the mileage requirement on the website is now showing 50K for Biz and 70K for First. Just few days ago, it was 22.5K for Biz and 27.5K for First. I then sent a tweet to AlaskaAir to confirm if it's correct and they confirmed the website is the correct. Basically this is the same price as US-Asia. My guess is US-Asia will be devaluated soon.
