I probably won't bother with the AC Vacations elite or domestic North America market. What fare classes would qualify? Tango+ and Latitude sounds foreign to me, but my travel would be to either Asia or Europe. Probably using a one way consolidator fare so fare class very important. Don't mind paying higher if difference is <$150.
