I love paying for flights with points and miles and David and I try to maximize the points we earn on nearly every purchase we make. But, as anyone who’s tried to book awards flights knows, those “free” flights are often hard to find. Airlines tend to raise the amounts required for convenient times and schedules, offer less award seats on a flight than you need, or simply don’t offer award flights at all on certain flights. Taxes and fees on some airlines and at certain airports (I’m talking about you, Heathrow!) can turn a “free” flight into an expensive proposition. For flights to Asia from DFW, we think Korean Air is the ticket. (Our opinion holds even with all the saber-rattling currently going on between our government and North Korea, although we’ll definitely keep an eye on developments.)
