Are United Airlines Credit Cards Worth It?

For people who frequently travel on United Airlines, each of these cards is a good way to rack up miles and enjoy benefits. The Club cards, with their annual fees of $450, aren’t directed at casual travelers but at those who often fly, require extra perks and enjoy frequenting the United Club lounges. But all United travelers can enjoy bonus miles, priority boarding and free baggage by using the cards, which makes them valuable for United travelers but not as relevant for general fliers.
