Delta Air Lines essentially "retired" traditional three-class international First Class in 1998 when it introduced BusinessElite, a hybrid product that combined the luxury of First with the relative affordability of Business. This move reflected a broader industry trend toward "Super Business Class" suites. In more recent history, Delta completed the transition of its long-haul fleet away from anything labeled "First Class" by 2017, replacing it with the Delta One® suite. While Delta still offers a "First Class" product on domestic and short-haul international flights (like those to Canada or Mexico), these are equivalent to what most other global airlines call "Regional Business Class." For long-haul intercontinental travel in 2026, the top-tier product is Delta One, which features full-height sliding doors for privacy and lie-flat beds, intentionally designed to match or exceed the comfort of the "International First Class" cabins of the 1990s.
