Just caught this thread and read the first few posts and had to say this from the other side of the fence:
How do you know you're asking a FlyerTalker to marry you? The dialogue goes something like this:
Him: Will you marry me? [producing beautiful ring of excellent size, cut, clarity, and color]
FT Her: Did you get miles when you bought that?
Him: Um...what? No. I bought it at Tiffany.
FT Her: Oh. Well. Hm. Can I think about it?
OR, in our household, it might go a little something like this:
Him: Will you marry me? [producing beautiful ring of excellent size, cut, clarity, and color]
GG: Did you get miles when you bought that?
Him: But of course. I earned miles going through the shopping portal*, bought it during a triple miles bonus promotion, using a miles-earning credit card, which I opened and got 25,000 miles with the initial purchase.
GG: Oh, DARLING! [throwing arms around him] You had me at triple miles bonus promotion! Of COURSE I'll marry you!
* Obviously learned from The Great Circuit City TV Purchase of 2005, in which my SO made a significant online purchase without using the shopping portal, only to subsequently return it in favor of a completely different TV that, by coincidence, netted us miles in the purchasing.
