Amtrak is trying to make a case for being the vehicle of choice as people start considering travel again. It’s offering a buy-one-get-one-free deal (BOGO) on traveling in a private roomette this summer. The offer is available from April 6-16 for travel from June 1 to September 30 of this year. The deal is pretty straightforward: When you purchase a private roomette, you get to bring a travel companion along for free. It’s an alluring way to travel while maintaining your distance from other travelers. To get the discount, drop in the code “C645” during checkout.There are limited lines on which the deal can be applied, but they are spread across the country. You’ll find the BOGO tickets available across 15 routes. That includes the Auto Train, California Zephyr, Capitol Limited, Cardinal, City of New Orleans, Coast Starlight, Crescent, Empire Builder, Lake Shore Limited, Northeast Regional, Silver Star, Silver Meteor, Southwest Chief, Sunset Limited, and Texas Eagle. A roomette gets you a pair of beds in a private space with a window, fresh towels and linens, and access to a bathroom and shower. You’ll also get lounge access at stations, priority boarding, and complimentary meals. Here are some of the lowest prices you’ll find for two people traveling to major destinations along these lines.

Though, it did say last week that fully vaccinated individuals are able to travel safely inside the United States.
