Well, its good to know I am wrong then

But that being said, (without this being taken as me just finding something to complain about anyway):

It still seems to me that for a customer service business that happens to be an airline, you would think that the e-mail they would anticipate my reaction: that the voucher will not result in double points. And, indeed, my bet is that unless someone asks about it, they don't give it.

I never like when I feel like I am the one that has to demand something be fixed, I'd prefer the company just fix it. Is that a fair complaint?

Its probably more cost-effective to require the customer to ask for the double points, but maybe it would honestly just have been more customer friendly to offer the $10 in some other way (drinks, etc.). Yes, more people would redeem it at face value, but the reality is, they aren't losing $10 in retail value when they serve you $10 of drinks.

Incidentally, my flight this morning out of JFK was great. Such a beautiful day in in the northeast today!
