FlightCancellationStatistics->matching->total


#1

We’ve recently noticed that the FlightCancellationStatistics matching total (the total number of originally scheduled flights belonging to this airline/airport) for time_period=today greatly outnumbers the total for prior or future days.

As an example querying today for ident_filter=KPHL
time period, destination, origin, total
twoDaysAgo (577, 578, 1155)
yesterday (590, 582, 1172)
today (1776, 1645, 3421)
tomorrow (504, 503, 1007)
plusTwoDays (415, 418, 834)

Is this a bug or is there a reason the flight totals would be off by this much on day of, but return to normal if looking back a day? We’re attempting to calculate the % of flights delayed/cancelled and this data doesn’t seem to allow for that in its current format.


#2

An event from earlier today allowed erroneous data through our system. Engineers are continuing to address the data errors and correct them.
