Anyone booked flights through chase know what the middle economy class is? I see it with more than one airline and it's a bit higher than basic econ, but not the regular econ fare. I typically don't book flights through chase, but have so many points to burn and can't find this fare through united.

Edited: Clicked through with the middle fare listed and I got the BE warning. Not sure why it shows up twice when searching on the chase portal.
