Mke arrivals departures1/29/2024 Better have them around the shops than looking at a luggage belt. After all many people still have to wait a couple of minutes for their luggage. Although airports still try to separate them early, by routing arrival passengers down this is probably a commercial decision since it might induce consumption in the shops. I now see many airports that drop passengers exactly in the same floor as departures. Also, you require less space since people always follow the same route and arrivals don't cross with departures. This kind of setting makes it easier to route persons (to add signs, etc). Arriving passengers would actually be dropped on the ground floor. But I've seen a few older airports where this didn't happen. It's also more comfortable to the departing passengers to just walk in to the airplane.Ĭurrently in most airports I know departing passengers cross with arriving ones in the commercial area. I think they were born as a consequence but it's now a reason to support keeping the same design. Probably as a consequence airport designers also realized that having the departures above puts passengers approximately at the airplane level and therefore jet bridges were born. Natural light and the sense of depth through the windows is a factor of comfort. This way you keep them adjacent.Having departures in the first floor allows not only for larger areas but also for natural light, either by using large windows or sky lights. And you might want to have those technical areas not only at ground level but also underground. It s also easier for employes working on the field to enter leave the building. With this setting you can occupy part of the space in ground floor with technical areas, car parking, luggage handling and also arrivals. The comfort on departures is probably an important factor in an airport and it's where the airport can make extra money. Not that arrivals are not important but they stay less time and require less space. You could split the building differently, but using one floor for each group is, in principle, more rational.Īlso we can easily assume, as others suggested, that airports worry more with departing passengers than arriving ones. Since we have 2 types of airport users (arriving and departing) it's natural to keep each group together, at the same level. Once you have the need for 2 floors you start thinking what to do with them. Many small airports only have one floor because they have little traffic and enough space to keep everything at the same level (stairs, elevators, etc all occupy space and cost money). A good reason for having 2 floors is because it saves horizontal space and that is precious for airplane parking. Note that this setting (2 floors) is typical in large airports. With airports people just realized that this setting works. Either by creation, but also by trial and error (or a mix of both). Note that these are just assumption based on observation. It also notes there are more than a few exceptions to the convention. I borrowed this last point from this thread discussing the same thing. People coming off a plane are not going to care that much about how high the ceilings are. That means you can use the extra space on that ground floor for all the behind the scenes stuff (such as baggage handling).Īlso, many airport terminals are big 'hanger' designs and having departures (where people spend more time) upstairs means they get the space and the high ceilings, etc. In arrivals people are generally moving through the airport and leaving as such not as much space is needed. The other concern is that you need more space for departures - people spend more time there and that's where an airport can make money with shops and things. Once baggage claim is on the ground floor it makes sense to have arrivals there to. Therefore it makes sense to have baggage claim on the same level to save the not inconsiderable energy it would require to move baggage up a floor (and then inconvenience people having to take it down again). Warning, guesswork ahead - I couldn't find anything definitive.Ĭhecked baggage is handled at ground level (i.e.
