Always verify the specific aircraft and seat type before booking — Lufthansa's website and ITA Matrix routing tools can reveal whether a flight is Allegris-equipped, and if so, whether it features the enclosed Business Suite or a standard Allegris business seat without a door. As of the 2024-2025 rollout, Allegris is concentrated on select A350 routes with expansion continuing, so many long-haul Lufthansa flights — including some U.S. and Asia routes — still operate with the airline's older, non-suite business class.
