When Northwest Airlines was acquired by Delta and their Skymiles program merged, I thought I could use my frequent flier miles to get a discount on the ticket, but turns out I had to purchase their credit card (even if I am a Gold Elite member) to use the discount.
So we flew Korean Air this past December '11 to January '12, and never looked back. The stop over in Incheon was longer, but I got to stretch my legs and not worry about rushing to the next flight (or not being able to board on time).
Their in-flight multimedia screen was wonderful too, and kept me distracted from my worries. The flight attendants were very courteous too. However, you have to select a meal aside from beef, and might always have to default to bibimbap, which was fine the first time but having it three times out of the four flights (2 flights to, and 2 going back) was too much.
And they'll thank you very much for your "corporation" (cooperation)
