I searched but couldn't really find an answer. Which is more accurate Google or Flightstats? I've been following TAP Portugal 204 (EWR - LIS) for the past month or so since I will be flying that on 5/18. We have a 3 1/2 hr layover in LIS and have loved the on time performance since we were going to go out to a cafe. This week on Google it has consistently taken off on time however shows that it's delayed between 1-2 hours. (30 mins ago it was saying 1 1/2 hour delay, now is back on time). Flight stats has reported an on time or early arrival every day this week. (Early this am FS was reporting it as landed but Google showed it as appearing to still be in the air for another hour. ) any thoughts?
TIA
