I used to use Matrix but stopped using it after finding that a lot of the time it doesn't actually catch certain deals available only on airline websites themselves. Now I'm back to individually searching every airline website.
And, "QPX Express was a lower-touch way to let companies start experimenting with QPX without needing full on biz-dev contract cycles", per someone I know with some inside knowledge.
