The 737 MAX and A320neo family recently received ICAO aircraft type codes, making them easy to track on Flightradar24. Previously, the only way to track these aircraft was via the registration of each aircraft. That made seeing the entire fleet difficult and time consuming. With the new type codes, it is now possible to easily track every aircraft of the type at the same time.
