Tried MileValue - several emails back and forth, then no response.
Tried for the same search with Award Butler, back and forth a bit, then again, no response.
Tried to email them both back several times and neither responded to requests for at least a response like "sorry, couldn't find anything." or something. Nada.
Still looking for a good award search service. I have a relatively simple search, but I just don't have the time to do it.
