Sources of information about flight times and delays [duplicate]

I booked travel from Perth Australia (QF648 2350 11 April 2019) via Melbourne Australia to Christchurch New Zealand (QF133 0715 12 April 2019) but there was a delay in Perth. Because I was going to miss my connection in Melbourne, Qantas transferred me to Air New Zealand in Melbourne so I could travel to Christchurch via Auckland on flights NZ722 and NZ555. I think there was also some sort of delay with one or other of those flights but I'm not sure, and I got to Christchurch too late on 12 April 2019 to travel to the town where I had pre-booked accommodation so I had extra expenses in Christchurch.

I’m now trying to complete a travel insurance claim but I can’t remember all the details. Is there a free open-source list of that kind of thing? It’s not like I have to prove in the claim that the delays occurred because I would guess the insurance company is going to check that in any case; but I would like to get the details right.
