I emailed CO and told them that if they were going to "pretend" I wasn't on one of their flights by denying me a segment credit, than why don't we forget playing "pretend" - I WON'T be on any more of their flights.
I received no response. What a surprise. Noone in OnePass has been listening for a couple of years.
AA matched my Platinum status last week, and I look forward to flying with them again, while CO morphs into another lackluster airline - like Delta.
