The list of exclusives outdated and inaccurate as we've added many award airlines to EF.

In addition, not only does ExpertFlyer have more AA data and the same UA data, but we allow you to use all of it in more flexible ways:

- AA awards show actual class values (Z1, C4, U5, etc), not just a + or - based on the number of passengers you enter for the search.
- 14 days of results are available with one search
- A Mobile version, with all EF features, is available now.
- Flight Alerts allows you to be notified when award/upgrade (or any other) class not currently available becomes available.

Either way, you are welcome to try us for 5-days, free of charge. Just sign up and start searching immediately. KVS doesn't appear to offer a free trial on his website, but if you ask for one I'm sure he'll accommodate you. Try us both out (and AwardNexus.com as well) and see for yourself what is the best solution or combination of solutions for your needs. That's really the best way.
