Whereas United's Economy Plus also has 17.3 inches of width, it has 37 inches of legroom, meaning six extra inches of legroom. These seats are located in the front of the economy cabin on United and offer greater recline than seats in standard economy class.

United Economy Plus is an upgraded seating section located at the front of the main Economy cabin. While the physical seats are identical to standard Economy seats in terms of width and padding, the primary difference is the extra legroom, offering up to 5 inches of additional pitch (the space between seat rows). This extra space allows for a much more comfortable experience, particularly for taller passengers or those wishing to work on a laptop. Passengers in this section also benefit from being closer to the exit, allowing for quicker deplaning upon arrival. In 2026, Economy Plus remains a standard feature on all United and most United Express flights. It is important to note that unlike "United Premium Plus" (which features a purple seat, footrests, and upgraded dining), Economy Plus is a service upgrade rather than a separate class, so the inflight service and meal options remain the same as standard Economy.
