I would have booked a flight with them (KLM) recently, having found flights for the routing I wanted on their website timetable, but could find no information about baggage allowances for this multisector European flight.
On contacting KLM by mail for clarification my query was transferred to Austrian, who told me that they (KLM) did not operate the flights I wanted to take, so could not inform me about baggage.
I then replied sending a screen shot of the timetable, and was advised that no baggage was included free of charge for this routing, and that I had not given them sufficient information in the first place about the flights I had envisaged taking.
Strange that flight numbers and airport codes were not considered sufficient information in my original email, but sadly it seems that KL/AF could do with reading emails before copying and pasting what turn out to be unhelpful replies at best.
