Is there a website that has real-world international routes?thanks

sorry, didn't know Avsim had a separate flightplan forum.

Short answer....no.This is because there are so many routes that are possible, however many ai routes are used in real life.Hope this helps,Jason.I

One shortcut is to check the online travel sites. Most of them have the option to check for travel between cities non-stop. It doesn't cover every airline, but you might get some info from that. Also, most of the major airlines have timetables you can download either in PDF or in an actual program.
