A colleague at work tells me that he has a United/Continental credit card that waives first-bag fees on all Star Alliance carriers, not just UA/CO. He claims that with the card, he's been able to have both US Airways and Air Canada waive bag fees on his flights. This doesn't sound correct to me, but he swears that it's true. He doesn't have elite status on any Star carrier, so I don't think he's incorrectly attributing his frequent-flyer benefits to the credit card. He also doesn't know the name of the card. Free bags across Star certainly isn't a published benefit of even the top-tier UA/CO cards like the Presidential Plus. Anyone have any idea what he's talking about?
