Fortunately for me, I remembered that I hadn't yet bought my Amtrak tickets for this trip this morning, and today was the last day I could buy them using the 3-day-advance-purchase National Association of Railroad Passengers 10% discount. It's not much money on such a small ticket, but there's no sense in throwing money away, and besides, the small discounts add up to the point where they sometimes end up being more than my annual NARP dues.
The connection coming back is tight, and there's a reasonable chance I'll miss it, in which case it will cost me the one-way BART ticket and a $12 cab ride from the station to my apartment, but the return ticket on Amtrak is good for a year and I can use it the next time I do this train-to-airport thing, because the conductors don't seem fussed about me using an "upside-down" (opposite direction than denominated) ticket.
