CABIN CLASSES
Y, W, J, and F across the desk's twelve carriers.
The four-letter shorthand is more than IATA naming. Each cabin carries its own pricing logic, bag rules, and refundability.
Y · Economy
The base cabin. Pricing breaks into Basic Economy (no seat selection, no changes, often no bag) and Main Cabin (seat selection, paid changes, often a bag on transatlantic). The desk indexes Basic Economy separately because the bundle math changes the comparison.
W · Premium Economy
The fastest-growing cabin on transatlantic. Pitch usually 38 inches versus 31 in economy, with a wider seat, an extra bag, and priority boarding. On Delta it's Premium Select; on United, Premium Plus; on BA, World Traveller Plus; on Air France, Premium Economy. Norse Atlantic and JetBlue's Even More Space are paid-upgrade premium seats inside an economy cabin, not separate cabins.
J · Business
Lie-flat seat on all transatlantic and transcon premium. Delta One, Polaris, Club World, Upper Class, La Première's predecessor product on AF: every legacy carrier has rebranded its business cabin in the last decade. On domestic short-haul, "First" is functionally a recliner business seat, not a true F product.
F · First
True international First survives on a handful of routes. AF La Première to CDG, LH First to FRA and MUC, BA First on the LHR shuttle. Most JFK-LHR shuttles run J as the top cabin. If you see "First" on a domestic American or Delta ticket, that is premium-domestic, not international F.
Transatlantic premium note
Premium economy on the New York transatlantic has become the value play. The cash gap between Y and W is usually $400 to $700 round trip; the comfort gap is meaningful, especially on the eastbound red-eye. The cash gap between W and J is usually $2,000 to $4,000; the comfort gap is meaningful but the cash gap rarely justifies the cabin unless you sleep through the flight.
