Facing a vanished booking with a closing boarding window is stressful; compile the original confirmation email, payment receipt, and a screenshot of the kiosk failure. Submit these via https://amtrak.pissedconsumer.com/review.html and request immediate reinstatement or rebooking on the next train at the same fare. Ask them to privilege day-of cases and to confirm the restored reservation number and boarding instructions in writing so you can proceed without missing the trip. Please request a single confirmation and a concise timeframe so progress is visible while support works the case.
