Celestar340,
of course, I don't think I'll have only Silver/Ruby with CX...just did a quick check on my travel schedule within the next few months...since they reset my status count on Apr 15...if there's no change to my current plan, I'll have to wait until some time in mid-August to accrue the 40 sectors needed for Gold/Sapphire (otherwise I should have enough by June)...
in fact, by August I'll have taken about 80 flights with them, within 9 months, but still just barely make the middle-tier...80 more flights (or 64 more, if I choose to fly J) to make Diamond...
