How to Get Tail ID?

Hi,
Can anyone please help me to get tailid using flightxml API.
I have only flight number and is there any possibility to extract tailid based on only flight number?

Please advise.

Thanks

You can call the AirlineFlightInfo function on the faFlightID that you want to retrieve more information about. One of the fields returned is the tailno of the aircraft, if we know it.

Thank you.
