I’d still rather take Amtrak over United Airlines any day of the week
In the dining car I've dined with and spoken to: an author, a spec-ops E-5, a BNSF executive, the owner of a private rail car, and a Brit living in France who is a historian of medieval European history. In the Pacific Parlor Car of the Coast Starlight, I've drunk brandy with a Scottish tourist who knew his British railroad history. You can't get that kind of experience on a plane.
The last time I flew United Airlines, it was a great experience because I accumulated enough Mileage Plus points to get a first-class seat. But with the new restrictions on flying, I may never fly anywhere again.
