Neither I call it the "gangway". I mean..airlines appropriated ships terminology for their terms anyways..calling planes ships, having captains, port, starbord, aft etc etc...some airports even call their terminals piers and PHX calls itself "Skyharbor".
Jetway is the place where planes park and has a Jetbridge that links the passengers to the terminal..(dunno how to explain....where u walk fm the plane to the terminal) it requires a 2 storey terminal to accomodate a Jetway...
Planes park on the tarmac, and more specifically, at the stand. The covered bridge which connects any terminal (be it two or one level) to the aircraft is either an:
a)Jetway (manufactured by the Jetway Co.)
b) a loading bridge/jet bridge
Alright, Alright, Everybody Calm Down, This is not the topic to get into an argument about, Call it what you want, Jetway, Jetbridge, Gangway, Ramp, White Thingy I just cannot believe that people are arguing over what to call a stupid Boarding Ramp
To be absolutly precise, it's a Passenger Loading Bridge.
"Jetway" is one of many companys that build this equippment. "Jetway" has come to be used as the common name, just as "Kleenex" is used for tissues, or "Xerox" for photocopies. (at least in the USA) I'm sure simular examples can be found in other countries as well.
Read with interest the above replies to RL757PVD's query. 'Jetway' and 'Jetbridge' are, I gather, very much American terms. In Australia we refer to the connecting walkways from the terminal to the aircraft as "aerobridges" and interestingly enough the same name is used in Singapore, Bangkok and in London. There are as Iahcsr pointed out probably many other local names for "jetways" around the world. Whatever you call it I'm sure anyone in the aviation field would know what was meant. Even got the drift on the "white thingy"!!!!!!
