So if they don't scan my ticket on the LSL our tickets for the next 3 weeks are all cancelled? Do I get a refund? If no, why do they cancel? I know it frees up inventory but we paid for all of these trains almost 9 months ago. I will be tracking down the conductor on every train from here on out but no idea what I'll say if a conductor gives me an attitude (I will make every effort to bite my tongue and call customer service).
If you aren't checked in electronically as present by a conductor or AC, yes, all segments on that reservation will be cancelled 2 hours or 2 stations after departure if on an LD. Other reservations aren't affected. It is why some of us break reservations at overnight layovers and return trips, to put in firebreaks. I do that myself now.
If they're called about it, Amtrak agents will try to reinstate the itinerary. However, since the problem may not be discovered until boarding the second train or the return, sleeper accommodations released may have been resold with no alternatives available. In that case they'll refund the accommodation charges. If you want to bail on the trip, they'll refund. You have to contact Amtrak, though, otherwise you'll be considered a "no show" and your fare forfeited.
As you can see, the consequences of a missed scan/check-in are severe and can have a catastrophic impact on travel plans, so I don't think verifying with the conductor is a bit out of line.
What I do is politely tell them I had a scan missed in past that caused problems with that trip and could they please verify? That is the honest truth for me, but I wouldn't condemn telling a little white lie. I've not had a conductor react badly to that.
On my last few trips, the conductor or AC has always scanned my ticket themselves on all segments. It was so consistent I thought they cracked down on the policy (conductors scanning/lifting tickets themselves
is policy set forth in the Service Standards manual). Apparently based on the posts here I was just lucky on those trips.
