XXXX partnered with Citi to issue a branded credit card. One of the benefits of the card is priority boarding. After reading the fine print, I applied, was approved, I received and used the card in accordance with their rules. I am now taking a trip, and I do not have the priority boarding. They tell me I had to purchase the ticket with the branded Citi credit card. However, there is nothing I can see in their fine print saying that.
