I am flying on a NW ticket on KLM metal. What is KLM's policy regarding tardiness? If a passenger is late for a flight, say gets to Schiphol 20 minutes after take-off, do they automatically book him on the following flight? I am booked for the 7.25pm AMS-JFK flight, and I know I may be late. Will they charge me anything, or simply put me on the next flight (at 11am the following day)?
