Business Class
Don't expect a wide-body long-haul experience — Aegean's entire fleet is narrow-body (A320/A321 family), so this is a European-style short-haul business class, best evaluated against Lufthansa, ITA Airways, or British Airways short-haul rather than Gulf or Asian long-haul carriers. The best value is on routes through Athens where connection times and lounge access align well, and travelers should specifically confirm blocked-middle-seat business rows are shown as 'true' business class fares, since Aegean sells multiple fare types that dress up economy seating.

Business Class
Seat consistency is the biggest variable — the A350 and newer 787 deliveries offer a more modern, private feel than some older A330s and 777s still flying on certain long-haul routes, so it's worth checking aircraft type before booking rather than assuming a uniform product. For the fullest experience, prioritize flights connecting through Istanbul, where the flagship lounge (with its cooking stations, library, and even a golf simulator) is as much a reason to fly Turkish as the cabin itself.

Allegris / Business
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.
