Amtrak is having a winter sale that that could take you far -- or as far as you want to go -- by taking 20% off the price of coach tickets through mid-April.
The deal: The Winter Sale discounts rail travel between a number of cities nationwide. For instance, one-way discounted tickets from Los Angeles cost as little as $48 to Flagstaff, Ariz.; $50 to Albuquerque; $42 to San Francisco; $109 to New Orleans; prices don't include tax. These rates apply to coach seats.
When: Good for travel through April 14, but you must book by Jan. 24.
Tested: You don't need any special code to get the deal prices; the Winter Sale rate will pop up when you make a reservation.
Using Amtrak's website, I selected an overnight journey aboard the Southwest Chief, a daily train from Los Angeles to Chicago by way of Arizona and New Mexico, among other destinations. A trip from L.A. to Flagstaff takes roughly 10 to 11 hours each way. (If you want a more scenic long-haul route, consider the Coast Starlight, which runs from Los Angeles to the Bay Area during the daytime.)
