Will that only work for AA? I'm trying to help my sister find some nonstop flights on either AA or UA, but not basic but I can't seem to work out how to do that. Here are screenshots of my query and results. It's showing me basic fares on UA. Is there a single query I can do that will exclude basic from both airlines? Maybe some way to say "anything where the second to last letter in the fare basis is not B."

Or, maybe another way: I want to exclude B on AA and N on UA. But if I simply exclude B and N "blindly," I'll exclude N on AA, which is not what I want. And of course I don't want to run one query for AA and then a separate search for UA. I'd like to be able to see both airlines in the results.

And yes, I know this is the AA forum and not the UA forum.
