The only reason to use KLM is because AMS makes a better regional hub than LHR.
Probably correct prior to T5.
But what point is having a "better" hub if the d1ckheads can't transfer luggage. It's now exactly two days after my arrival at CGK, and I still have no suitcase. The reference on the manually completed PIR form does not result in any information being available on the KLM baggage tracking site.
What a bunch of w@nkers.
