They say the less, the better.
Being an air traffic controller and a frequent traveler is not a good combo at all. You see, when your flight suddenly halts in the middle of the taxiway, you'd groan, "Oh no, give us some ample spacing for each arrival. I need to fly ASAP!" or, "Why aren't we taking off yet? There is no inbound traffic at the final approach runway 06?". Then, you'll check FlightRadar24 to monitor the traffic around the aerodrome traffic zone. But, I stopped doing it because it's stressing me out, to say the least.
