Are airline credit cards worth it? Yes, but with a catch

The United MileagePlus Business Card has a permanent place in Andrew Goodman’s wallet for one delicious reason: The card offers expanded award availability, so Goodman can use his miles more cheaply to indulge his passion for bespoke bourbon. 

“It’s the only airline card I will keep,"says Goodman, a systems administrator from New York. “The checked bag benefit and lounge passes are nice but I get the most benefit out of the added Saver award space you get with the card. I use my miles for last-minute trips to visit friends in the bourbon community.”
