I'm looking for a resource (ideally like a Google Map) which contains a list of all OW destinations and that allows you to click on a given city and then see all the nonstop OW flights that originate from that destination and lists (or indicates with map lines) the cities to which the flights travel.

It can be pretty time consuming to look up the Wikipedia entry for every airport I'm interested in flying to/from and then check OW airlines under the "Airlines and Destinations" section. Thanks for any help you can offer!
