Are there any flight search engines for planning a group get-together with the cheapest flight costs?
For instance, suppose a small company gathering (much like the one I'm currently planning!), with employees in the following cities:
- Wichita, KS
- San Francisco, CA
- Seattle, WA
- Chicago, IL
We want a single city (likely one of the four on the list, but it wouldn't have to be), with the cheapest combined round-trip air fare for a 3-4 day gathering.
Are there any tools (free, or otherwise) to do this sort of search?
