We have found two issues comparing values between AirlineFlightSchedules and FlightInfoStatus APIs using the FlightXML3.
Both issues are different in nature but in both cases they are born due to a mismatch in the information between both APIs. The issues happen with flights AI607 and AI9623.
AI607 is not present within the AirlineFlightSchedules in anyway, but it is present in FlightInfoStatus. And AI9623 happens in the other way around. It is a daily flight shown in the AirlineFlightSchedules API, but in the FlightInfoStatus the flights shows every second day. AI9623 is a daily flight indeed.
How can we deal with these situations?
