One of the biggest differences between premium economy and economy is the seating and legroom. In premium economy, you can expect more spacious seats with extra legroom, making those long haul flights a little more bearable, especially for taller passengers and those with back or joint pain.

Premium Economy is a distinct "third class" of service in 2026, positioned physically and financially between standard Economy and Business Class. While it shares the word "Economy," it is not considered the same class as the main cabin. On long-haul international flights, Premium Economy offers a significantly better hard product, typically featuring wider seats with 5 to 7 inches of extra legroom, deeper recline, and often a dedicated footrest. The service also differs: you usually receive an enhanced meal service served on real chinaware, a larger entertainment screen, and an increased baggage allowance. Some airlines even provide a dedicated check-in lane and priority boarding for Premium Economy passengers. It is important to distinguish this from "Economy Plus" or "Main Cabin Extra," which are just standard economy seats with a few extra inches of legroom. Premium Economy is its own cabin with its own curtain, making it a "mid-range" luxury option. In 2026, travel agents and corporate booking tools categorize it separately because the price point is often 2 to 3 times higher than standard economy but significantly lower than the lie-flat seats found in Business Class.
