Many modern airlines have moved away from a traditional "First Class" cabin in favor of an enhanced Business Class or a high-end "all-business" or "premium-heavy" configuration. Low-cost carriers like Southwest Airlines, JetBlue, Spirit, and Allegiant notoriously lack a traditional First Class, though JetBlue offers a premium "Mint" service on select routes. Internationally, many major carriers have removed First Class from their short-haul and medium-haul fleets; for instance, Ryanair and EasyJet in Europe are strictly "single-class" economy operations. Even legacy carriers like Delta, United, and American Airlines often only offer "First Class" on domestic narrow-body flights, while their international long-haul "flagship" service is branded as Business Class (e.g., Delta One or United Polaris). Other airlines like Air New Zealand and Turkish Airlines generally do not offer a First Class cabin, focusing instead on providing a world-class Business Class experience that bridges the gap for luxury travelers.
