The following is what McGraw-Hill's  "Aviation Internet Directory - A Guide to 500 Best Aviation Web Sites"  had to say about AirCharterSolutions.com:

Here's something I would have expected to see more of by now. Filling those charter flight empty legs online. No, the process at AirCharterSolutions isn't completely automated. In fact, the site simply provides the means for air charter companies to list their upcoming empty legs. However, searching by day, month, year, and region is automated and handy. Just enter your proposed trip dates and see if you match up with a scheduled charter flight. Found a match? Just contact the respective air charter company. The rest is up to your negotiating ability.

Aesthetically, AirCharterSolutions receives top honors. It's built for speed, beauty, and functionality - a lethal combination in the Web world. The design, layout, and navigation obviously were the work of professionals. I'm sure you too will have nothing but kudos to contribute as you click around the site.

Note: It should be made clear that AirCharterSolutions is not a travel agent, broker, or air charter operator. The company simply provides the means for air charter companies to list their empty legs. Or in their own words, "AirCharter Solutions is an informational Web site designed to provide the consumer with knowledge of alternate air travel accomodations through the use of classified ads posted by various private air charter companies."
