Another prominent feature is being proactive
. Your customer support department can anticipate issues that may occur. Everyday practice will give a list of most common problems, and your service agents can address them beforehand by creating manuals, tutorials, FAQ sections and online knowledge bases.
As an example of proactive service we can look at the Airport Fast Park at Baltimore Washington International Airport. This service not just provides parking slots for arriving travellers. They meet each car and direct the driver to a free parking slot. They greet guests with a fresh morning paper (and an umbrella during the rain), assist with the luggage. They board passengers to a comfortable shuttle, so their journey starts in a relaxed mode. These little things make a huge difference. And mind you, Airport Fast Park is not an airport service, it's a private establishment that set its own unique goal: to make flight experience more relaxed.
