But then at the bottom of the article it said

>They also still have fun with flight numbers for instance running flight 1776 between Philadelphia and Boston; flight 1492 to Columbus; AAA777 to Las Vegas;

AAA777.

Am I missing something?

The "AAA" is a typo, they probably mean "AA777" for American Airlines 777[1].

A far as why the number 777 is amusing, it's gambling. The combination 777 is a jackpot on a slot machine, Additionally AA777 is a great hand (full house) in poker.
