In conjunction with the OTP collapse on various LD trains at inconvenient times (October 2014 for the Cap, for example) my use of the east-west trains has basically disintegrated. I'm now to the point that I use Amtrak on an almost exclusive north-south basis and Virgin America (or VIA Rail) on an East-West basis. I'd love to take Amtrak east-west some more, but for a host of reasons (I have Gold on VX and Premiere on VIA) the other options are simply more palatable.
Also, the CC situation ironically undermined any need to take Amtrak to the same extent: I can now get 40% of my TQPs for SE from my cards, so I only need to spend $5-6k on Amtrak for SE now (I functionally needed to spend about $9000-9500 before...I usually scooped perhaps 1000-2000 TQPs off of the 100-point minimum), and that $6000 spend nets me 43-44k points/yr (maybe a hair more depending on how some bonuses are calculated, if Double Days still applies, etc.). That plus the other $35k/yr spend on the CC getting me about 35-40k as well, so...I should probably be looking at somewhere in the range of 80-90k points/yr on Amtrak...
...and believe me, I can run up $6000 on Amtrak without too much trouble. Without getting into the nitty gritty of it, trips to Florida (either to duck high VX airfares out of WAS/NYC or for dedicated business purposes) should cover a majority of my TQP needs, with the remainder being trips to/from Washington and one or two Starlight, Cascades, and/or Montreal trips.
I know I'm so many standard deviations off of the "normal" customer and there are some oddities in my earning patterns, but it seems that when a comprehensive overhaul of a program results in the spend needed to earn status dropping by between 1/3 and 1/2 while spend costs generally rise, something is a bit off.
