A Lufthansa-operated flight booked through United: where to start with seats
Lufthansa offers advance seating in My bookings; United also describes seat changes among its app functions. These two self-service entry points do not prove that every United-issued booking will display every Lufthansa seat option. If one system cannot retrieve the flight or show the seat map, ask the ticket seller or operating airline which booking reference and channel apply to that sector. Do not buy a replacement flight simply because a seat map is unavailable. For Lufthansa seating, advance reservation is offered until two hours before departure, and the entitlement is to a seat category rather than a guaranteed number. Review the fare, available category, and charge for that specific sector before confirming; a United app feature does not establish Lufthansa seat-fee eligibility.

Important unknowns
- United–Lufthansa reference lookup and cross-platform seat synchronization were not verified.
- Live canonical owner and nearest-page content are UNKNOWN because the sitemap index could not be retrieved.
