United Airlines is now offering travelers a way to pay for checking their baggage for an entire year. United's baggage subscription service allows travelers to prepay their standard checked baggage charges for an entire year. Travelers can customize their subscription online by selecting the number of bags, the number of passengers and the preferred geographic regions. The new program started earlier this week. United is also offering annual subscription service for Economy Plus seating. "The Economy Plus and checked baggage subscriptions offer our customers more of the comfort and convenience they value year round," Scott Wilson, United's vice president of merchandising and e-commerce, said. Subscriptions can also be given as a gift. United is currently the only U.S. carrier to offer an annual subscription for its extra-legroom economy seating and checked baggage service charges. A "global" checked-baggage subscription includes two bags, and costs $799.
