Similar devices are used for astronauts to enter spacecraft, which are installed at the appropriate height of the launch tower.

Before the introduction of jet bridges, passengers normally boarded an aircraft by walking along the ground-level ramp and climbing a set of movable stairs, or airstairs on aircraft so equipped. Mobile staircases or "ramp stairs" are employed at many airports around the world, particularly smaller airports, terminals supporting low cost carriers, and overflow using remote stands during peak travel demand at larger airports.
United Airlines tested an early prototype "Air Dock" in 1954.<ref name="baskas">{{cite news|last1=Baskas|first1=Harriet|title=A short history of the much-maligned jet bridge|url=https://www.usatoday.com/story/travel/flights/2016/02/24/jet-bridge-jetway/80806044/|access-date=1 March 2016|work=USA Today|date=25 February 2016}}</ref> The first operational "Aero-Gangplank", as it was dubbed by inventor Lockheed Air Terminal, was installed by United at Chicago's O'Hare Airport in 1958.<ref>{{cite news |title=Briefings...

==Advantages== Jet bridges provide all-weather dry access to aircraft and enhance the security of terminal operations. They are often permanently attached at one end by a pivot (or rotunda) to the terminal building and have the ability to swing left or right. The cabin, at the end of the loading bridge, may be raised or lowered, extended or retracted, and may pivot, to accommodate aircraft of different sizes.<ref name=Gesell /> These motions are controlled by an operator's station in the cab. The cab is provided with an accordion-like canopy, which allows the bridge to dock with aircraft with differing shapes, and provide a nearly weather-proof seal. Additionally, many models offer leveling devices for the portion of the floor that makes contact with the aircraft; this allows passengers to slowly transition from level aircraft floor to sloping jet bridge floor. As such, jet bridges provide enhanced access to aircraft for passengers with many types of disabilities and mobility impairments, as they may board and disembark without climbing stairs or using a specialized wheelchair lift.
Some airports with international gates have two or even three bridges for larger aircraft with multiple entrances. In theory, this allows for faster disembarking of larger aircraft, though it is quite common, especially on aircraft such as Boeing 747s and Boeing 777s, to use one bridge for only passengers in first class and/or business class, while the other bridge is for the use of passengers in economy class. In some designs, the second jet bridge would even extend over the aircraft wing, being suspended from an overhead structure. This was, for example, originally adopted for most wide body gates at Amsterdam Airport Schiphol. The Airbus A380 is unique in that both of its two passenger decks have outside access doors and so using loading bridges for each deck is possible, having the advantage of faster aircraft loading (in parallel). Faster loading can lead to lower airport charges, fewer delays and more passenger throughput for the airport, all factors which impact an airline's bottom line.
Though loading bridges are usually permanently attached at their terminal-building end, leaving only the cab free to move, this is not always the case. Those at Melbourne Airport's international terminal, and at Hong Kong's former Kai Tak Airport, are anchored in the middle and movable at either end to permit the terminal building-end to be raised or lowered to connect with either the departures level or the arrivals level of the terminal building.
==Disadvantages== Jet bridges may occasionally collapse; incidents have happened at airports in Sydney,<ref>{{cite web|url=http://archives.californiaaviation.org/airport/msg13033.html |title=Investigations begin into collapse of Sydney airport walkway |date=2001-02-01 |website=California Aviation Alliance |access-date=2013-01-09 |url-status=dead |archive-url=https://web.archive.org/web/20130418093336/http://archives.californiaaviation.org/airport/msg13033.html |archive-date=2013-04-18 }}</ref><ref>{{cite news |url=http://voin42.blogspot.be/2012/03/nsw-singapore-airlines-jet-damaged-when.html |website=Voin |last1=Aplle-yes |title=NSW: Singapore Airlines jet damaged when aerobridge collapses |date=2001-02-01 |access-date=2013-01-09}}</ref> Hong Kong, Seattle, Los Angeles,<ref>{{cite news |url=http://newsinfo.inquirer.net/47591/2-injured-when-jet-bridge-collapses-at-la-airport |website=Inquirer News |title=2 injured when jet bridge collapses at LA airport |date=2011-08-25 |agency=Associated Press |access-date=2013-01-09}}</ref> Baltimore,<ref>{{Cite web|url=https://www.usatoday.com/story/travel/2018/12/29/bwi-jetway-bridge-collapses-baltimore-washington-airport-injures-6/2443192002/ |date=Dec 29, 2018 |title=Defective bracket discovered on collapsed jetway bridge at Baltimore-Washington International Airport|first=Dalvin|last=Brown|website=USA TODAY |url-status=live |archive-url=https://web.archive.org/web/20230131201927/https://www.usatoday.com/story/travel/2018/12/29/bwi-jetway-bridge-collapses-baltimore-washington-airport-injures-6/2443192002/ |archive-date= Jan 31, 2023 }}</ref> and Islamabad,<ref>{{Cite news|url=https://www.thenews.com.pk/latest/378674-jetway-collapse-at-islamabad-airport-injures-one|title=Jetway collapse at Islamabad airport injures one|date=9 October 2018|work=The News International|access-date=22 October 2018}}</ref> among others.
Airports frequently charge increased fees for using loading bridges on stands as opposed to mobile stairs; therefore low-cost airlines such as Ryanair have avoided using these wherever possible.
===Marketing=== Marketing space on jetways was uncommon until the early 2000s when HSBC launched their campaign "The World's Local Bank".<ref>{{Cite web|date=2009-10-13|title=New campaign for the worlds local bank|url=http://www.hsbc.com/1/2/newsroom/news/2002/new-campaign-for-the-worlds-local-bank|access-date=2020-11-30|archive-url=https://web.archive.org/web/20091013130818/http://www.hsbc.com/1/2/newsroom/news/2002/new-campaign-for-the-worlds-local-bank|archive-date=2009-10-13}}</ref> Peter Stringham, head of marketing for HSBC worldwide,<ref>[http://www.hsbc.com/1/2/newsroom/news/2002/new-campaign-for-the-worlds-local-bank New Campaign for World's Global Bank]</ref> worked closely with Lowe's, the Group's global agency, in developing the campaign which required a single global platform.
