I'm in a situation currently where I think I MIGHT need to make a claim, I have expertflyer, and I'm trying to trace the delay back as the aircraft has been late all day today and a bit going back into yesterday. FWIW flight is SK723, not part of this sub of the forum I know, but I googled and ended up here

According to flightradar24 SK723 today will be operated by EI-SIA which operated the following since this morning.
SK1683 ARN-AGP dep 56m late, arr 39m late
SK1584 AGP-ARN dep 80m late, arr 62m late
SK718 ARN-HEL dep 69m late, arr 57m late
SK723 is scheduled to depart at 20:05 but SK718 landed in ARN at 20:27.
Do you have a connecting flight to catch at ARN? EU compensation if applicable will be based on the actual arrival time at your final destination. If you miss your connection in ARN and the next flight is not until tomorrow SK should give you accommodation and meals in ARN regardless of the reason for the delay.
SK's IRROP handling is not up to scratch. Make sure you get everything sorted out at the airport if possible. There is no telephone support in the evening and when I was stranded in CPH in the summer I was sent to a hotel and told to check checkmytrip to find my alternative flight. Unfortunately they eventually booked me to a wrong city (London instead of Manchester) but I could not call anybody to have it sorted out until the morning.
However, their EU compensation handling is excellent! They have a very well designed
claim form which you can complete online and you don't need to know the reason for the delay, times of arrival, etc. since the airline has all this information. All you need to supply is your booking details, which flight caused the delay, which flight you were rebooked on and your bank details.
If the delay is not due to unforeseen circumstances such as weather, they are very quick to respond and pay compensation. I had mine paid into my bank account within 3 days!
Hope you don't have to make a claim but if you do you will be dealing with a good airline.
Edited to add: SK723 departed at 21:08 and is expected to arrive in ARN at 20:56 local time, 46 mins later than schedule.
