Yes, the KVS Tool fully supports Etihad Airways flights.
However, it is not quite clear what it is, exactly, that you are looking to do with your tickets.
I bought 1 ticket last week for $1050. Trying to see if the "T" fares are still available for the dates I need in June/July for my wife and kids. I should have bought 4, but last week I was the only one who was planning to go (family reunion), but wife decided that she wants to go too. Current fare that comes up on Etihad.com is close to $2200 per person which is more than double what I paid for the same flight(s).
