The pre-merger Alaska Airlines fleet contains four different variants of the Boeing 737, with one of those (the 737-900) outfitted in either of two seating configurations. Only the 737-800 and the 737-900 "V2" configuration are outfitted with a dedicated section of extra-legroom seats near the front of the economy cabin. In the others (737-400, 737-700, and 737-900 "V1"), the only way to get additional legroom in the economy cabin is to snag an exit-row or bulkhead seat. For sake of comparison: * 737-900 "V1" has two exit rows with additional legroom, and one bulkhead row with additional legroom, for a total of 18 seats, in a 165-seat economy cabin, with additional legroom. * 737-900 "V2" has two exit rows with additional legroom, and four rows at the front of the economy cabin designated "premium", with 3-4 more inches of legroom compared to non-"premium" non-exit-row seats, for a total of 30 seats, in a 162-seat economy cabin, with additional legroom. The worst configuration is the 737-700, where one of the exit rows has only two seats each side of the aisle; this brings it down to only 16 economy seats available with additional legroom. The best is the 737-800, which has five rows of "premium" plus two exit rows, for 42 seats with additional legroom.
