Check your flight →United's newer Boeing 737 MAX 9 First seat is a recliner with winged headrests and a curved divider between neighbors. The paired layout means window passengers must pass their seatmate to reach the aisle. Seatback entertainment, wireless charging and USB-C power distinguish it from the earlier cradle-seat interior.
