Just before Easter my 15 year old son was due to fly LHR - HKG on Lufthansa via Germany. He was offered GBP 250 and overnight at the Hilton to fly 24 hours later. He accepted.
It seems this is common with LH on the HKG route; over the last year both my wife and daughter have separately been sounded out for compensation and a later flight by LH. But the offers for them both fell through.
