Megabus, the country's leading low-cost express bus service, is offering 200,000 seats free for travel January 4 through March 1. Log on, enter your route, dates, and the promotion code "gofree" to see if you can snag one.
Megabus operates throughout much of the Northeast, Southeast, and Midwest, and to Toronto. Typically, it concentrates on limited-stop express trips of eight hours or less to/from its major hubs: Atlanta, Boston, Chicago, Pittsburgh, New York, and Washington, D.C. It uses modern double-decker buses that, according to reports, are quite comfortable and provide free WiFi onboard. Typically, each route provides at least two daily frequencies, one all-day and one overnight, but many routes offer multiple schedules. Pittsburgh-New York, for example, operates four times a day.
This is the kind of promotion that won't last long. But even if you miss out on the "free" ride, you can ride at very low cost: Regular Megabus fares start at $1. Even without the promo code, for example, a trip from New York to Pittsburgh on January 25 shows two schedules at the $1 fare. And, this far in advance, fares for other times are $5 to $15. As the bus fills, there are incremental fare increases, so buying as far in advance as you can is clearly the best way to score a really cheap trip.
