I have a OnePass Plus CC which provides for a baggage fee waiver on CO if I use the CC to book my flight. I used my CO FF miles to book a flight on UA. I then used my OnePass Plus CC to book a companion tix via the UA website (obviously couldn't use the CO site to book a UA flight). Will my baggage fee(s) be waived by UA, now that CO and UA are the same and I used my OnePass Plus CC to book the companion tix?

The CO website says that the baggage fee will be waived on CO flights only, but aren't CO and UA now the same?

TIA
