In urban public transport, provision is made for standing passengers, often called straphangers[1][2][3][4] or standees,[5] to rationalize operation and to provide extra capacity during rush hour.
However, in 2010, Ryanair, a low-cost airline proposed a "vertical seat" design for use by standing passengers on its aircraft.
A higher standing ratio allows for more passengers in a given area, but detracts the perceived quality of the transport, in particular over long distances.
[7] This metric is normally limited to urban mass transit, due to intercity transport normally only offering seated travel.
[8] Standing passengers are susceptible to suffering falls and other injuries, particularly elderly people.
