Origin Field Containing Interesting Data


#1

Hi

I’ve noticed about 8 occurrences of this so far in my own data usage. The origin field of a few flights contains positional data rather than an ICAO.

Example:


https://flightxml.flightaware.com/json/FlightXML2/FlightInfoEx?ident=BAW252&howMany=15&offset=0

Output (5th one down):

That’s a known glitch that sometimes occurs for flights, but we’re working on trying to eliminate the causes for that.

More specifically, these two flights on May-23-2016 were actually the same instance, but we incorrectly claimed them to both be in flight at the same time
BAW252-1463963140-ed-0001
BAW252-1463722008-airline-0128

That can occur when we start tracking the flight from a position that is far enough from an airport and don’t associate it with the flight that we already know about. Hopefully we’ll have a fix for it in production soon, but it’s been an ongoing issue that has been happening to a small number of airline flights for awhile.

Ok!
