Flew there in 2003, we were six aircraft.
I confirm all the above regarding permits, fuel quality and airport expenses.
Bear in mind that you will most probably be instructed to fly IFR routes and reporting points, especially by Odessa ATC.
P.S. Don't even think of using Odessa airport toilettes.
Hi there AfricanEagle,
Sounds like a great adventure you've had in 2003. Will keep your warning in mind, although some things might have changed since then for the better. Will report here.
Cheers, Kero
