How Are Flight Numbers Determined?

Sat Dec 15, 2001 1:19 pm

Something I've always wondered about.

Who decides that the 9AM flight between LAX-ORD is flight #1206. Or that the 1:20PM flight between DFW-EWR is flight #488?

How are those numbers determined? Is there any methodology to that; say even numbers correspond to north and west routes and odd numbers to south and east routes?

Do the "mainline" (LAX-JFK) routes get the low digit (say 10-99), "secondary" routes (SJC-LAS) get middle digit (100-999), and the "podunk" routes (LAX-BFL) get high digit (1000-9999) numbers?

How does that work?

In timetables they show the difference in flight numbers between codeshare and regional flights.

For mainline routes, I'm not to sure. But I know many Transcon and International flights are double digits.

Ex. Delta: ATL-LGW #002
