  1. Match the total seat count and the number of seats in each cabin with the comparison above.
  2. If your assigned aircraft registration is available, compare it with any verified registrations listed below.

348 seats (77B)

Best seats to consider

Compare the side and center banks in this exact numbered plan before selecting. A two-seat side bank can suit a pair, while middle banks keep a larger party together. Source-marked doors and facilities help identify cabin boundaries; a bulkhead symbol alone does not establish unlimited legroom.
