New to this, and would be grateful if someone could explain why a June 7 easyJet flight the company told me was cancelled does not show in the history, while other cancelled flights show as cancelled. On other flight tracking sites, this particular flight shows as UNKNOWN (as does the aircraft’s incoming flight that day), and I see that if a flight is cancelled it apparently should not show in the tracking history as unknown, but as cancelled. Curiously, the company’s own flight tracker showed the cancelled flight as operating. Is this flight tracking data thorough? Can a company manipulate flight tracking data in any way?
