FlightStats

I really can't recommend them. All too often their data is not up to date. Right now it's 20:05 and I'm still waiting for me 17:40 flight to depart. AENA reports it correctly as delayed until 20:45. But FlightStats still show it as scheduled lol! Useless.

The live tracker map suddenly became not available after I used it for five hours without explanation. It simply said data will be available after taking off. It has taken off for five hours for God sake. I was beside myself thinking of the worst about my only daughter ( yes I might be too anxious). A message of "the flight was fine but data is not available due to whatever reason "will be fine to a mother. I will never never never use this site. Thank God I found flight data from another tracker before getting heart attack in the middle of night. A heartless site, it is! Totally heartless!

The website pretends to be "flight stats" but it also has separate website - cirium. I work with statistics and economic research and subscribed for standard subscription. No useful information was found apart from current flights timetable, which I did not need at all. In advertisement of the subscription they had departures and arrivals but did not mention that it regards only to current flights +/- one day. So, unsubscribed immediately after trying, unfortunately losing small amount.
They pretend to be flightstats, there's no stats, just tracker.

Someone very dear to me was in a flight from hi chi Minh city to singspore on 17 January 2024 on Flight TR 307 (code share SQ 8539). The flight took off an hour late which is ok. But halfway through tracking this flight, flightstats updated to show that the flight was descending, in the middle of the ocean! It continued to descend all the way down to 22 feet and one can only imagine the terror anyone who had a loved one on this plane must have felt. I used another tracker which showed the plane was still cruising at thirty five thousand feet when according to flightstats, it must have been landing in the ocean. I was petrified until I kept refreshing and some time later, it updated to show the same status as the other tracker. I believe they did not fetch real time data which would have accounted for the 1 hour delay in taking off, and simply assumed the plane would be descending to land at 6 pm instead of 7. Either way, I have learnt never to rely on this website to track any flight related data ever again.
