I wish everyone would stop complaining about how KVS gets it's data. It's none of my concern. It's between KVS and the data provider. If you have serious qualms about it, you always have the option of discontinuing use of KVS.
KVS is an extremely valuable tool for me that is not matched by any other service. EF is excellent but it is only minimally helpful with OneWorld award searches. I would hate to see KVS disappear.
