I redeemed Chase points for a one way on Korean Air online (HKG-JFK with an overnight in ICN). I'm little nervous having never flown Korean Air before when I read the Credit Card Verification Form that I need to bring it to a Korean Air office.

I have searched and cannot find any info on the blogs or FT except that for flight check-in I need to have my credit card that I used to purchase the ticket with me. Can someone confirm that I need to bring this Verification Form and credit card with me on my trip and show at Check-In if asked? Do I need to do anything before I leave the US (flying CX to Asia)?
