Vaigai வந்துருச்சு, ஆசையில் ஓடி வந்தேன்

You yourself saw how the traveler got confused. The passenger wanted to keep his alarm based on the 'possible' delay. And its not showing the trend, its simply an averaging the sum of total delays instance. For the trend he has to check arr/dep history on avg arr delay column. I guess lack of understanding is not my part.
