Premium economy's big selling point is more space. The seats are an inch or two wider on average than the typical coach seat, and the rows are farther apart, offering several more inches of legroom. Most premium economy seats recline, and many have footrests. How much space you actually get depends on the airline.

Premium Economy is a distinct travel class that sits between standard Economy and Business Class, offering a "middle ground" of comfort and service for a higher price. Unlike "Economy Plus" (which is just a standard seat with more legroom), Premium Economy features a dedicated cabin with significantly better hardware. The seats are wider (often 19–20 inches), have a deeper recline, and include extendable footrests and headrests. Passengers typically enjoy a "pitch" of 38 inches, compared to the 31 inches found in standard coach. In 2026, the "soft product" of Premium Economy has also been elevated; travelers often receive upgraded dining served on real china, a wider selection of complimentary spirits, larger entertainment screens, and a "sustainably sourced" amenity kit. On the ground, a Premium Economy ticket usually includes Priority Privileges, such as a dedicated check-in lane, increased baggage allowance, and earlier boarding (Group 2 or 3). It is the ideal choice for long-haul travelers who want to avoid the high cost of a lie-flat Business Class bed but require more physical space and "perks" than a standard economy seat provides.
