NEW YORK (AP) — Before you board a flight this holiday season, think twice about stuffing that carry-on full of gifts to avoid a checked bag fee. You might get charged anyway.
Already armed with an exhaustive list of checked bag fees, some airlines are stepping up their enforcement of weight limits for carry-ons. This may lead to aggravation if an airline agent weighs your bag at the gate and then charges you.
Although weight limits for carry-on bags are mostly on international flights, George Hobica of Airfarewatchdog.com says charges on domestic flights may not be far behind.
One practical reason for weight restrictions is that they limit an airline's liability for accidents, such as when a heavy bag falls from an overhead bin and hits someone. But they're also — you guessed it — a way for carriers to generate more fee income. Under congressional pressure, major U.S. airlines vowed earlier this year not to charge fees for carry-on bags. But they haven't ruled out widening their restrictions on the weight of those bags.
Although there are practical restrictions on their size, none of the major U.S. airlines puts a cap on the weight of a carry-on bag on domestic flights — but several do on international flights. United, for example, sets a 44-pound limit for coach passengers flying within Asia or the Middle East. American Airlines puts a 50-pound limit on carry-on bags for trips to and from the Caribbean and Latin America. The airlines don't charge for the first bag on those routes, but you may get stung if your carry-on tops a limit and you've already checked one bag. A second checked bag fee could run as much as $60 or $70.
Big international airlines, such as British Airways and Lufthansa, have more widespread weight limits on carry-on luggage. Caps can range from as little as 18 pounds to as much as 50. But most of those airlines also let passengers check one bag for free, lessening the chance that passengers will get stuck paying an unexpected fee.
