Problem with IATA and ICAO Flight codes

I’m using the class3 for find some flights but i’ve some problems with IATA and ICAO flight codes.

For example:

YWXXXX and ANEXXXX → Ok, correct detect
IBYYYY and IBEYYYYY → No, only detects the first.

¿And why the app don’t track companys like ryanair and easyjet?
¿Someone can provide me a list of the companys wich the app don’t track?


Can you provide examples? IB101 and IBE101 both work in FlightXML to track the same flight. lists all the operators we have coverage for. Some operators use different operating flight numbers from the flight numbers they sell tickets as.
