I would like to give a big ^ to the KVS team.
A couple of weeks ago I bought a subscription in order to prepare for a redemption of 600K AA miles.
Thanks to the tool I was able to book 6 outbound J CX seats from CLT-DFW-LAX-KUL. This morning I was able to snag the return flight, from BKK-HKG-JFK, 5 seats in F, 1 in J. I'll be on the outlook for another F seat opening up so I can get my other daughter into F as well.
I know a lot of peole say they can search airline sites and find redemptions, but I think this tool made the search very easy, especially when I had multiple sessions open while cobbling this all together.
