This took place in October. I deliberately cancelled the itinerary at the airport, just in case they pro-actively rebooked the ticket and I ended up as a no-show for the first segment. This is where I was informed that LH was the point of call for the refund. The agent did state that a comment was added to the booking explaining the reason for cancellation, though I have no record of what was actually written.

Flight disruptions happen, but the need to regularly call or email to get any kind of response from the airline is the most annoying aspect. On the telephone, there is no resistance to the idea that a full refund is due and so they pass it to the refunds team and assure me it will be dealt with. I should wait at least two weeks to see the refund. Then I have to repeat the cycle again. Via email, the request is either misunderstood, or they simply tell me that it is being handled already.

The process for such a refund is not defined by me, it should not be up to me discover it, airlines have to process refunds all the time. If they don't believe that a refund is due or if I should contact LX instead of LH, then LH should explain this, but they do not correspond. They only respond to direct contact.

Thanks for all the suggestions, I will attempt contact with the airline once more before a possible chargeback. No miles are at risk for me, whatever the outcome, it's a long time since I was LH Senator and I don't maintain a M&M balance having moved to another Star Alliance scheme some years ago.

Apologies if some of my comments come across as a bit of a rant!
