Proactive customer service.
Left home by train in the early morning, only to find out in the train that my flight to Toulouse was cancelled (one of many that day due to heavy fog) and my only offered replacement flight was a 2-stopper in the late evening with a complex connection in Munich Germany. I have poor visibility and was travelling by myself, and not looking forward to this, especially as I still had to sort a boarding pass for the 2nd leg of the trip in München with Lufthansa, and there being delays galore all day due to the weather. I tried calling the KLM helpdesk for 1,5 hours, but didn't get through. Same with the chat support.
When arriving at Amsterdam airport I headed straight to the service desks. But some sort of triage trio of KLM staff assured me there was no way to get a rebooking for another route and that all flights were full and that they wouldn't even allow me in the (long) line to talk to a desk officer. If I wanted to be booked on a different flight, i would have to pay for this out of pocket, the young man said. I walked off initially, but then decided I wanted to get in line no matter what, to be put on a standby list for a better flight. Argued my way in line with the triage trio and 45 minutes later, when I asked a friendly ticket office lady to be put on a standby list for a direct afternoon flight to a nearby (different) airport instead, she was very understanding of my concerns and arranged a direct seat on the alternative flight of my choice without any problems or costs. Instead of Toulouse, I was allowed on a Montpellier flight 1,5 hours later, so could go straight through customs and arrived in the afternoon after a pleasant and calm flight. It was difficult to get to see someone from KLM, but once I did they offered empathetic, friendly and flexible service. Appreciated.
