I think they hate their customers
I think they hate their customers. That can be the only conclusion after traveling with them on a number of occasions.
KLM has perfected the art of creating problems for their customers and then making those customers deal with the consequences.
They insist on physically checking passengers’ carry-on bags at the gate because there isn’t enough overhead bin space for everyone’s luggage. This is a problem of their own making. They charge such high fees for checked baggage that many passengers understandably try to travel with only cabin bags. Then, when the inevitable happens, everyone is inconvenienced while bags are tagged and loaded at the last minute.
To make matters worse, their flights seem to be delayed far more often than they should be. Delays have become something I almost expect whenever I fly with KLM.
What really stands out, though, is the attitude. Rather than making customers feel valued, the staff and overall experience often leave the impression that they’re doing you a favor by allowing you to pay for a ticket. Customer service feels transactional at best and dismissive at worst.
There are plenty of airlines that manage baggage, punctuality, and customer service far better. Unless you have no other option, I’d recommend looking elsewhere.
