OK, so I've seen a growing number of references to some potentially HUGE changes to the SkyMiles program later this year. I understand that there's a lengthy thread on TOBB discussing it, but I would like to encourage the start of some discussion over here so that the substantive content is here too--we are all trying to create the best community we can over here, right? So, I ask that people respond with several different things, if they're so inclined: 1) What details of the rumored changes have found their way to the grape vine? 2) What are your thoughts on the changes? Will it kill Delta? Will other airlines follow suit? 3) What are you going to do to plan/prepare for the rumored changes? 4) What will you likely do moving forward after the changes? Switch airlines? Switch CC spend? etc. The most detail I have seen is on The Points Guy's blog. From that, I'm a bit nervous about the possible changes. I am primarily a leisure traveler. I fly maybe 1-2 round trips a year for work. I am clearly not someone who Delta would be targeting as the biggest beneficiary under ANY loyalty system, but I am a bit hub-trapped in Atlanta and am generally very supportive and loyal to the airline. I will be a big loser under a revenue-oriented program. If the change is to a system that is similar to Southwest's Rapid Rewards, then my inclination will be to start treating Delta exactly like a treat Airtran: I'll fly them only if they're the cheapest option, and I won't put forth any effort to gain miles/points through any means other than what I get flying with them on those cheapest fares. I'd probably move entirely away from any Delta-branded Amex card and likely away from MR as well, unless Amex can add another big transfer partner.
