Iberia Airlines. Frankly speaking, this airline offers seats with the biggest legroom in Europe. During long-haul flights, Iberia continues to prioritize passenger comfort. Economy Class travelers are provided 30 to 34 inches of legroom, while Premium Economy passengers benefit from 37 inches of legroom.

In 2026, the title for the most comfortable seats in Europe is a toss-up between Turkish Airlines and Air France, depending on the flight duration. For long-haul Economy, Turkish Airlines consistently wins praise for its "generous" seat pitch (the legroom between seats), which often averages 31–32 inches, and its adjustable headrests that actually support your neck. Their new 2026 "Crystal Business Class" also sets a high bar for short-haul comfort within Europe. Air France has also revamped its fleet, offering ergonomic seats with high-density foam and better lumbar support even in Economy. For those seeking "Premium Economy" comfort on a budget, Virgin Atlantic (operating from the UK) remains a top contender for its plush, leather-style seating. If you are looking at low-cost carriers, Jet2 is frequently cited by UK travelers as having more comfortable, "pre-reclined" seats than Ryanair or Wizz Air. However, for the absolute best seat "feel" in 2026, look for flights operated on the Airbus A350 or Boeing 787 Dreamliner, as these aircraft feature better cabin pressure and humidity, which makes the seat feel more comfortable for your body over long distances.
