I was due to return from Bangkok to London via Mumbai on 21 April. I checked in for the flights on the morning of departure using the airline's website, so have boarding cards for both flights. On arrival at Bangkok airport in the evening I was informed that the Mumbai to London flight had been cancelled and was refused boarding on the Bangkok to Mumbai flight. In fact, the Mumbai to London flight had not been cancelled. It operated to schedule.

It has been suggested that by checking me in for these flights the airline was then under an obligation to carry me on those flights (that it probably wouldn't have had if it had not checked me in), so I may have a claim against them for failure to do so (e.g. for hotels, meals, etc. for the 6 days I had to wait before they did get me home). Comments please.
