Yes it is very fast for upgrading. One new Chinese Captain spent 1.5 years as a 737 Captain and now is moving to the left seat of a 787 so in 6.5 years from off the street to 787 Captain with 5000 hours TT. Some guys have all the luck. The growth here is huge but for ExPats they only want experience with time on type for the most part. The young Captains upgrading here in China is unprecedented and almost mind boggling how many are upgrading. They do however have a very slow process which takes almost 6 months and numerous checks.
