Earlier this week, US Representative Dan Lipinski introduced a plan that would standardize the size of allowable carry-on bags.
The Illinois Democrat’s bill would require the Transportation Security Administration to set up templates on luggage conveyor belts that would block pieces larger than 22 inches x 18 inches x 10 inches. Pieces that exceed the limit would have to be checked in.
Currently the airlines set their own guidelines, and those rules vary greatly. American Airlines, Delta Airlines, and United Airlines require bags to be no larger than 45 linear inches - height plus width plus depth. Airtran sets the limit at 55 total inches. Virgin America allows 50 inches. Southwest and JetBlue’s Embraer jets allow 24 inches x 16 inches x 10 inches (on its Airbus planes, JetBlue sets a generous 26 x 18 x 12 standard).
