Yes I did, the first year I didn't even request for the waiver, I got a much welcomed letter advising I had been waived. Surprised but happy. The second year I asked for it because my spend was higher than the first, granted. This card was obtained while in Hong Kong and in about 6 months I will ask again.

With the CX citibank card I have had no such luck so guess which card I am spending more with?

miles4all - I didn't include the HKG immigration in my measurement of efficiency and for that matter the Singaporean immigration also. 68 gates is more to do with the size of the airport and the unmanned train system is really quite good. At least CX recognize this and set up a lounge "The Per" to address this big airport problem.

CLK is efficient because of the great transport system to and from the airport, the usage of natural light to minimise electricity, and very spacious checkin areas where even during peak times there is still ample space. You don't have to line up for restaurants which is handy when conducting last minute business and with heightened security the speed of security checks is way ahead of the rest. Singapore is a close second, I like the wood look and it's almost like you are in a hotel in some areas. Either one are great to travel through but CLK to me is more advanced (it's also newer of course).
