My trip back on Korean Air Flight 36 from Atlanta... 12 hours and 53 minutes to Incheon. Seats situated aft of 747-400 bulkheads are a common spot for families with babies and mounting "in-flight" cribs--old hat for any Everett payloads engineer at Boeing.My "47C" seat is across the aisle from a rear bulkhead... three families with three young infants! Ugh... 13 hours! Honestly, they were nice families.
