Economy class, also called coach class (or just coach), steerage, or standard class, is the lowest travel class of seating in air travel, rail travel, and sometimes ferry or maritime travel. Historically, this travel class has been called tourist class on ocean liners and third class, or even fourth class, on railways.

In North America, it is known as coach class by companies such as Amtrak. European railways call it second class. Standard class is used in United Kingdom and Ireland. It has been re-branded in some cases to broaden expectations. In Canada Via Rail now refers to coach as Comfort class. In India, the lowest class of service was branded third class under the British colonial rule. It was re-branded as second class following independence to avoid its former segregationist connotations. Today Indian Railways offers Economy AC-3 also in the same class.

Generally economy class seats consists of a seat, sometimes with a fold-down tray, that may recline. The seat may also include a pocket attached to the back of the seat in front for storage of small items such as magazines. Depending on the configuration of the passenger compartment, luggage can be stowed in overhead racks or at each end of the coach cars.
