Which flights can I register for?

SmartDelay is built to track almost all major commercial airline flights, but there are limitations against airlines/airports that do not report data regularly. 

You can register any flight where the airline accurately reports the announcement to FlightStats. If you try to register a flight that does not meet these conditions, you will not be able to register for the flight. 

Each flight of a journey with multiple connections requires its own registration. You can register up to 2 flights per data pack purchased.
