When we are asked to pick someone up at an airport to monitor them while they are out of town, this brings some special problems that we need to address. As you can imagine in the post 9/11 era, airport security is at an all time high and getting access to someone inside the airport is much more complicated than ever before. In some airports, we cannot even get to the departure or arrival areas. Airports also cause problems for a private investigator with getting hidden cameras inside. Airport security automatically thinks that we are there to case the airport for terrorist purposes, so the hidden camera goes out the door. Airports by themselves are complicated, busy places. People and vehicles coming and going in all directions makes following a vehicle into these areas tricky at best. Parking is a nightmare (i.e. we follow them into the parking structure and they find a parking place far from any other available parking spaces, we lose them because we cannot park soon enough to follow them, etc.) For those arriving at the airport, often they can exit the terminal in several places making it difficult to find them in the first place. Add to that the number of cabs, rental car shuttles and limos moving around in front of the exits and you have more risk of losing them. Drops offs can also cause problems for a private investigator inasmuch as the traffic volume and flow can be horrific. If someone decides to pull over quickly to drop off someone, we may not be able to duplicate that move.
What we recommend is that if you require private investigative work at an airport, use three investigators. It is better to spend more and get it done correctly than to spend less and run the risk that all your money is spent in vain when we cannot get you the video you need.
