Cactus beat me to the airport consulting side of the house. A good many of my fellow airport management compatriots have moved away from airport management and into the airport consulting profession. The pay is usually quite a bit better, travel opportunities do exist, and consultants will usually have offices in many different cities and countries.
Airport consultants specialize in many different areas including architects/engineers/planners, envornmental, facility management, financial/business management, marketing, public relations, etc to list a few.
Some of the more well-known airport consulting firms in the architectural and planning side would include Burns & McDonnell, Coffman Associates, DMJM Aviation, Gensler, Gresham Smith & Partners, HNTB Corp., Mead and Hunt, Michael Baker Jr Inc., Reynolds Smith and Hills, Stantec, URS Corp.
On the facility management side of the house is Airport Corp of America, for one.
Financial consultants include Airport Consulting Inc. and Parsons-Brinckerhoff.
One of the better known marketing firms is Vesta Rea and Associates.
Most airports that have capital projects underway will have a project managing consultant, as well. Parsons and URS also perform those services. Parsons does some of our airside project management.
Hopefully we've given you some ideas.
