The same five pillars as the hotel lists, with an airlines prompt bank, Skytrax/AirlineRatings/APEX inputs, and a seat- and route-aware Category Fit rubric. Airlines are scored on the cabin most passengers actually get — not the flagship seat in the press release.
Ten European-headquartered carriers ranked on the seat you will actually get, not the flagship in the press release — Turkish Airlines, Air France and SWISS lead, with long-haul-only and intra-Europe-only reorderings published alongside.
An airline is not one product. Lufthansa's Allegris is on nineteen aircraft. British Airways' Club Suite is on roughly two-thirds of the long-haul fleet. Turkish's Crystal suite is not in service anywhere. Our Category Fit rubric weights the hard-product score by the share of the fleet actually carrying the cabin, so the ranking describes a booking rather than a brochure.
Long-haul and intra-Europe business class are scored as separate sub-products and published as separate rankings, because they are separate products sold under one fare-class name.
Premium economy in Europe and family-friendly short-haul are the next two airline categories. If you work in airline marketing or product and want to be on the list of brands we contact before publication, drop us a line.
