Hey Sebring:
When you have a half million or so AE miles sitting in your account and you are only offered a few hundred for a cross Canada trip, they lose value very quickly. Making them non-status wipes out all of the value for me. Add-in that Tango means that my mitt full of upgrade certs can't be used, then I switch to another carrier at very little incentive, because price is the only incentive now to fly a Tango fare on AC.
Add to it that transborder Tango appears to be 50% mileage now also and the yawn gets bigger.
I had a TransCon Tango fare not even post last week. I can't even be bothered to phone/write/beg to get the paltry few miles posted. This is recent reality check for me and will weigh heavily on my next booking.
Now I will be flying AC again next week because the cheapest fare that I could get was on AC, a B class and therefore my certs will work. It was a late change of routing and my previous booking on United was now more expensive.
Non-status miles are now like copper pennies. If a teller gives them to you fine, but I wouldn't bend over to pick one up.
