FlyU6

Fly U6
Fly U6 is an airline in Grand Theft Auto: Chinatown Wars. It is only known because of "FlyBoy", a supposedly employee of Fly U6, who sent Huang Lee an email suggesting Fly U6 as an airline of choice.

"FlyBoy" 's email
In the email sent to Huang(FLIGHTS? is the subject), Fly U6 is said to have teamed up with the NOOSE, in order to give away free tickets to "rogue states" such as Afghanistan, Iraq, Libya and nearby countries with all expenses paid.

But in the last lines, he writes: "When booking, please note that Fly U6 will not sell-on your private details to criminals, hackers, or terrorists (outside of the US)."

The give away's motto is "Don't delay, book today".
