First class is the most exclusive cabin on a long-haul flight: a handful of private suites (often 3 to 14 seats) with more space, more privacy and more personal service. Business class is a larger cabin of flat-bed seats, usually with direct aisle access and, on many new aircraft, a door. On the same flight, first class is the higher and more expensive cabin. On most US domestic flights there is no business class at all: the front cabin is called "first class", and it is a recliner, not a bed.
| International first class | International business class | |
|---|---|---|
| Cabin size | Very small: 3 suites (Lufthansa Allegris, SWISS A350), 4 (Air France), 12 (BA's new A380), 14 (Emirates A380) | Larger: for example 70 seats (American's premium 777-300ER), 106 (BA's refitted A380 upper deck) |
| Privacy | Private suite, often floor-to-ceiling doors or walls | Flat bed, direct aisle access; doors on many new seats |
| Space | For example "almost one-meter-wide" (about 39 in) seats on Lufthansa Allegris First | Smaller seat, still a flat bed |
