I don't for QX/OO, or any of the other regionals that operate on behalf of other carriers such as Compass. The exception for me is codeshares from one major to another such as AA on a JL operated flight or AS on a DL. I might make a remark if there was something interesting to me about the flight such as my first QX E175.

I started my heavier flying after the CRJs went to OO, so until the E175 I could just sort by aircraft type and pretty much tell how many QX flights I had.
