Flight Reliability
Is your flight usually late?
Type a flight number and get its actual track record: how often it lands on time, how bad the delays get, and whether Friday really is cursed. It can't promise anything. It is still a pretty good tell.
Works with flight numbers (AS 331, alaska 331) and routes (SEA LAX, sea to lax).
