This is actually very interesting. I'm currently in DEL awaiting AF225 to take me to CDG and then going onward to ARN.

Originally, I was supposed to fly on AF1762 CDG-ARN which is scheduled to arrive at 1005. But, since AF225 is delayed by about 1.5h, I'm now rebooked on AF2062 scheduled to arrive at ARN at 1330, which puts my delay at just over 3h at my final destination. (Assuming they don't make up tons of time...)

What sort of paperwork do I need to actually file a claim? Do I need anything more than my original booking and the update from the airline? I'm a bit pissed at AF since this isn't the first time they delay my flight enough to miss my CDG-ARN connection.
