As long as I keep at least 25,000 miles in my account, I can use those miles plus $350 for an upradge to Business or First Class after purchasing an economy ticket. In the case of Business class upradge, that's a $5,000 ticket (Dallas to Seoul) for only $1300, for example. Well worth it to be able to lay down and sleep on that 13 hr flight! Plus, they loan you Bose noise cancelling headphones, a toiletry amenity kit (slippers, eye shades, toothpaste, etc.). And if you can make it all the way to a First Class enclosed suite, they even give you pajamas!
