Plat this year again, help from AmEx bonus. Husband now also Plat, lots of vacation trips, trip to china in M to use SWUs, probably about $11-12K for both of us. No rollover to speak of.
Miles are used ONLY to fly our kids to meet us on vacation or home for holidays. Rarely find anything at low level, usually at high levels.
Biggest change we have noticed in the last 2 years is that our upgrades have fallen way below 50%, despite higher status. Delta status is not worth much anymore. Too bad.
