This afternoon I will pick up a friend from the airport, so at breakfast I checked Google to see what time the plane will arrive. Scott, who was eating his oatmeal next to me, wanted to see where the plane was at that moment, so I showed him the location of the plane on the KLM website. However, then I noticed that there was a difference in arrival time of more than 40 minutes between KLM and Google.
I assumed it was just a glitch that would be gone after refreshing the page or by just waiting 10 minutes, but that was not the case. It’s now about 5 hours later and both sites still show a different arrival time. Who should I believe? If Google is right I need to leave 40 minutes earlier than planned, but if KLM is right and I leave early I have to wait 40 minutes at the airport.
I normally use Google for arrival information and so far they have always been right, but because this is a KLM flight I would assume KLM’s information is more accurate. I wonder where they get their data from, I guess there should only be one feed for this information (the plane’s on-board computer)?
Update: KLM’s information was right and Google was wrong, the flight landed at 2:22 PM. Good to know for the future. I still don’t understand why they give different arrival times though. Even after the plane had landed Google still showed 1:41 PM, and for tomorrow’s flight it now shows 1:49 PM, even though the flight has not even departed yet.
