WHAT'S CHANGING: Overhead bins on commercial planes are getting bigger, as airlines adapt to passengers who are maxing out their carry-on allowances.
SOME EXAMPLES: United is enlarging the bins on all 152 of its Airbus A320s. Boeing's newest 737s and its new 787 long-haul plane all include overhead bins that will hold more bags than their predecessors.
WHEN: United is set to begin enlarging the overhead bins on its Airbus A320s next month. Some other airlines are replacing overhead bins as planes come in for other interior projects.
