privatization trend

since 1987, many large airports outside US have been privatized and deregulated to adapt to a competitive aviation industry

passenger experience (overcrowding, parking challenges)

operational issues

decentralized

multiple unit terminals, each w complete facilities

short walking distances

decentralized pros

human scale terminals

lower passenger volumes in each terminal

safer and easier curbside design

decentralized cons

higher operational costs

transit requirements

hybrid

combines features of centralized and decentralized systems

hybrid pros

balanced walking distances

improved passenger flow management

line

high density

larger airports w higher staffing requirements

very high density

specialized airports w significant infrastructure, such as airline maintenance bases, where staffing is not solely linked to passenger traffic
