Just returned from a trip where I used it and saw several other people using the same app so yes it is becoming a travel tool amongst regular flyers that is more reliable than departure boards in many cases. We just spent 30 hours travelling over 4 flights and could see that it was impossible to meet what the board said, flightradra24 was much more accurate. By the way if anyone sees a red suitcase and a green suitcase on their travels please could I have them back, thanks to Air Canada for losing them, How about inventing a tracker that goes in the bag alongside the flightradar24 app.
