Week-long searches are currently supported for Star Alliance Award Availability.
This type of functionality is currently being considered for other Alliances as well.
Please consider this a strong vote in favor of adding this capability. I use OW with the JL method. The BA method seems to take 2-3 times as long for each search, and the straight OW method (as well as the CX method) doesn't differentiate between seats CX makes available to AM members and those it makes available to partner programs. Most often, I'm looking for CX seats. I've used the *A seven day search a few times for the AC miles I sporadically collect, and it makes the searches so much easier!! Thanks, KVS!!!
