IMHO, AGR is not worth the trouble of trying to collect and/or save up points anymore, especially for those of us in areas with limited Amtrak service. I have several thousand points (over 50k) in the "bank" right now, and am not trying to accumulate any more. I have the no fee BofA AGR card, solely to keep from losing points to expiration. We will burn through our points, someday, with a far shorter trip that we could have had in the old AGR. When those are gone, I will relinquish the AGR card, and continue to use my SWA branded card, which I use now.
Part of this is also due to the downgrading of amenities on Amtrak. It used to be far more fun to ride. Period. Can't really put my finger on it, but, the elegance is not there, the feeling of being an appreciated customer both on board and by corporate is not there.
The cost of sleepers is way higher than I recall it being in the past, as is the cost of coach. At least on trips originating where I live.
We might take the TE to San Antonio, or maybe the HF (if it still exists then) to OKC, for short visits, but both require an extra day due to late night arrivals, and early morning departures. SWA is more convenient........
Such is life, you don't know what you got, till it's gone........
