I still don't understand this. The same all-in flight from LHR costs only GBP 155.20 - LHR-AMS-MSQ, yet the first leg LHR-AMS on its own costs GBP 97.30, which is more than the LCY-AMS one-way flight at GBP 76.12. It follows that LCY-AMS-MSQ should be cheaper than LHR-AMS-MSQ, whereas KLM are actually charging 9 times the price for LCY-AMS-MSQ.

It's so frustrating that there's nobody at KLM who can sort out what must be an error or oversight. They'll lose my business and I'll lose the opportunity to fly from a convenient airport. It's lose-lose.
