Here’s what to expect besides extra legroom and a seat closer to the front of the cabin—if anything— when buying a ticket or upgrading to a seat in those sections on major U. S. airlines:
AMERICAN MAIN CABIN EXTRA: Priority boarding, dedicated overhead bins and complimentary beer, wine and spirits.
DELTA COMFORT PLUS: Priority boarding, dedicated overhead bin space, premium snacks and complimentary beer, wine and spirits.
ALASKA PREMIUM CLASS: Priority boarding and complimentary beer, wine and spirits.
JETBLUE EVEN MORE SPACE: Priority security lane and boarding. (And beginning with bookings later this month, dedicated overhead bin space and complimentary beer, wine and spirits.)
SPIRIT BIG FRONT SEAT: Priority check-in and boarding, one free checked bag, complimentary beer, wine and spirits and snacks and free Wi-Fi. This is only available if you book the airline’s most expensive bundle, the new Go Big option.
FRONTIER UPFRONT PLUS: A blocked middle seat plus priority boarding and dedicated overhead bin space and two checked bags if you purchase the airline’s Business Bundle. The seat can also be purchased a la carte without the extras.
SOUTHWEST: The airline plans to introduce its first extra-legroom section when it starts assigning seats, but it hasn’t disclosed any perks yet.
UNITED ECONOMY PLUS: Literally nothing.
