AirlineFlightSchedules - Wrong scheduled time of departure


I’m using the AirlineFlightSchedules endpoint to find this flight:

  • Flight number: TAP441
  • Date: Monday, November 4th, 2019
  • Scheduled time of departure: 07:55 am (local timezone)
  • Scheduled time of arrival: 09:15 am (local timezone)
  • Airline: TAP
  • Origin airport: LFPO
  • Destination airport: LPPT

Source: official site of Paris airports - https://www.parisaeroport.fr/en/passengers/flights/flight-departures/informations-flights-departures?paris=Paris-Orly&other=LISBON&comp=&date=20191104&following=0&schedule=-1&isArrival=False

Here are my query parameters:

  • startDate: 1572822000
  • endDate: 1572908400
  • origin: LFPO
  • destination: LPPT
  • airline: TAP

Here are the flight from the response:

Everything looks good except the scheduled time of departure and the scheduled time of arrival:

  • 1572850800 is Monday, November 4th, 2019 08:00 am (local timezone): it’s 5 minutes before the official time
  • 1572859500 is Monday, November 4th, 2019 09:25 am (local timezone): it’s 10 minutes after the official time

Does the AirlineFlightSchedules endpoint is updated at some time to take into account schedule changes?

Thank you.


Airline schedules are typically published on a monthly basis for flights up to 6-12 months out. The information is speculative and subject to change. Mid-month revisions often are not widely published until the start of the following month.
