Flying World Business Class with KLM is an experience in and of itself, with the best service, friendliest flight attendants, and the most delicious meals. You leave the plane feeling taken care of and, most of the time, wishing the flight was a little longer. It’s easy to fall in love with flying World Business Class with KLM, but there is one part of the whole experience that we never expected to fall in love with: receiving a KLM Delft Blue House at the end of every flight.
