Have flown with KLM a few times in the past months.
Every flight has been on time and the service has been great!
I have had many conversations over the phone with KLM regarding special requests for baggage, booking flights etc.. it’s always been a smooth and efficient, and they have always accepted my request to bring my guitar on board... there’s not many airlines that allow that!
All in all, would definitely choose to fly with them again.
There change of flight fees could be a little lower, but other than that, no complaints.
