Me, the husband, and two friends are taking advantage of the recent YYZ-Asia fire sale, and I've been closely tracking I-class availability in the hopes that we can avoid 12 hours in Y.

I've learned lots of new things:

• I can only upgrade myself plus one other person, no matter how many certificates I have.
• I can bring in immediate family plus one guest in the ANA lounge in NRT.
• Tracking I-space is confusing!

For those who are interested, here's a spreadsheet and charts showing what I'm watching. I'm tracking our flights (left) but also 2 weeks prior and 4 weeks prior, just to see if I can spot any patterns. Seems kinda random, but at least it keeps me entertained.
