I'm traveling to Korea with my family in July. We will be flying from NYC to Korea and we will be traveling with my father in law who is 85 and has some mobility issues. My wife has always used Korean Air and raves about it, but Asiana is significantly cheaper (around $270 per person, and there are 7 of us total). We could upgrade for $340 per person on Asiana and get extra legroom seats in the first few rows. Is there any reason to choose Korean Air over Asiana? My wife is hesitant because she doesn't know Asiana and is unsure of the service. I guess they also had a plane crash some years ago and maybe that is also making her hesitate. What do people think?
