I like it!
Obviously, I'd like it more if you'd add more airlines, esp. ones which are distance-based and therefore more effort to work out individually, such as QF and VA.
Thanks. Glad to know you like it. I am keeping adding more airlines.
Also, is it possible to remove the regular awards on routes that an airline doesn't fly? (Similarly, both the regular and partner awards for BA include "off-peak" entries, even when BA/Iberia doesn't fly the route and therefore they never apply.) There are lots of extraneous BA entries in particular as a result.
Real air route checking is very helpful feature. However, as my reply to IMH above, it is difficult to get reliable air route data, to filter out real available award entries. Right now I am evaluating one of data source and keeping search others. Hope this function could be online soon.
