While United is first out of the gate with this, don’t expect them to be the last. Expect the big airlines to follow United’s lead on this one in pretty short order. If I’m wrong, I’ll admit it here first.
United Airlines is implementing a $25 dollar service charge for checking a 2nd bag. You can read the details of United’s new policy here. In summary, you will pay $25 dollars to check more than one bag unless you are an elite Mileage Plus member or have Star Alliance Silver or Gold status. Passengers who purchase refundable fares, including First or Business class fares, will also be exempt.
