KLM Royal Dutch Airlines (KL, Amsterdam Schiphol) will give up its own daily Amsterdam-Detroit service on March 28 but continue to codeshare on four daily Northwest Airlines (NW/Minneapolis/St. Paul) services between the two cities. It will also terminate its Amsterdam-Aruba services on March 27 and its Amsterdam-Tallinn route on May 5. KLM will essentially transfer its Amsterdam-Aruba frequencies to subsidiary Martinair (MP/Amsterdam) that already operates three weekly services on the route and will increase its services to daily as of March 28.
