So with my trip I’m on, I’ve been quite religious about checking prices for the LD trains on the current day and for the days of our trip. Over the last couple of months I’ve noticed a trend where unsold sleeper accommodations are being dropped to low bucket or the +1 level a few days before departure. For instance, my in-laws will be riding train 8 from Seattle to Chicago on 9/19, the sleepers have been steadily filling up with the bedrooms showing 1-2 available at the high bucket price for a few months now. For which I assume there were only 1 or 2 available. As of this morning the last roomette was sold, the family rooms were both sold months ago, and now the bedrooms are showing 1 available at low bucket. I know I had read a couple of threads wondering why Amtrak wasn’t doing this sort of thing, but from what I’m seeing they may have started. My only other thought is these might be a result of last minute cancellations as somebody would not have received a refund so Amtrak is essentially getting paid at least twice for these rooms.
