I recommend AwardNexus because it's the only, to my knowledge, free tool to access ANA *A award availability data. (They still have a free membership for FT members). Not only that, it's *A search is also more powerful then some of the paid tools that also screen scrape ANA. The site is run by member ckpeter who has been very helpful to the FT community, so I like to give his efforts a ^ where I can since he's not a big self promoter.
