NEW AND SHOCKING: Southwest Airlines to Require Plus-Size Passengers to Book Two Seats Starting 2026

Starting in 2026, Southwest Airlines is introducing a major policy change that has travelers talking. According to the airline, passengers who cannot comfortably fit into a single seat (with armrests down) will be required to purchase two seats. Failure to do so could result in serious consequences—even being removed from the flight if the plane is full.

What Travelers Need to Know

Southwest Airlines’ new rule affects passengers who need extra space to fly safely and comfortably. The airline will require upfront payment for the second seat. If a passenger attempts to bypass this rule, gate agents will assess the situation individually.

This means travelers who try to avoid booking an extra seat could be denied boarding, especially if the flight reaches full capacity.

Who Decides if You Need Two Seats?

Gate agents and airline staff will make the determination on a case-by-case basis. They will evaluate whether a single seat can accommodate a passenger safely with armrests down. The policy aims to ensure both safety and comfort for all passengers.
