I was charged that amount by the agent, and another nearby agent indicated that United policies applied and that they would not recognize my 25K status for the baggage allowance.

I've requested a refund of the baggage fees through the "Send us an email" feature on their website, pointing out that both flights were on AC metal and that I received Zone 2 boarding. I assume that they will be able to tell that the flight was marketed and ticketed (?) by United.

I wonder how long a response will take. The automated email response indicates that it could take up to 45 days.
