Speaking of connections to airports, I wonder if the kiosks will be issuing Continental (err, sorry, United) codeshare segments as Amtrak e-tickets now?
It would be super cool if United could link up to this somehow so that UA OLCI (and the UA mobile app) would give you a valid Amtrak QR code, rather than the go-use-the-Amtrak-kiosk notice it gives you currently...
Speaking of Newark, any idea how the e-tickets will work with the AirTrain?
