For example, narrow-body airliners such as the Boeing and often operate from gates at airports designed for short- to medium-range domestic flights.

Since these flights usually require smaller aircraft, they have less room apportioned to them. As a result, wingspan is effectively limited by the size of the parking space the plane is allotted at the gate. So instead of the adding wingspan by making the wings longer, Boeing adds wingspan by going vertical with winglets.

In some instances winglets aren't necessary, because there are no constraints on space. For example, Boeing's hot-selling wide-body airliner does not have winglets. According to Gregg, that's because the operates from international terminals designed for larger jumbo jets.
