I've flown sixteen segments (all domestic and all on CO) since flights have resumed after the 9/11 attacks.

Here is how I rate it on a scale of one to ten (ten as being the best experience)

Airports in gen'l and Check in: Although it varies by airport (some are much more stringent than others) its been very good, lines not that bad and counter people and security very friendly and understanding, even the people in line are being much more friendly I do arrive 100 to 120 minutes early for my check ins. You got to love this new rule about ticketed pax only past security. It makes it so much easier to board and de-plane without a bunch on non-pax crowding the door and taking all the seats in the gate area. Same for the Prez Club. (8 out of 10)

Flights: Approximately 2/3 full overall, F is anywhere from 50% to 100% full. For example my IAH-IAD on Sat had 4 of 10 seats in F occupied and one was a non rev FA. (tough to rate, its great to be on an empty plane yet I feel bad that they are empty, its catch 22)

Ontime factor: All segments on time or early, simply amazing (10)

Food: (unchanged) but I'm lucky to still get food

Crew: AWESOME all the way around. Great communication, great service, great attitudes, it makes you really respect them now. (10)

Baggage: Some things never change, although with lighter loads, it does come out a bit faster. One good note, i never lost anything, (7)

In short, flying IMHO so safe now that I do not have any concerns about flying at all. This includes flying with pax of middle eastern descent which some members of this board have a huge paranoia about.

good luck and enjoy your flight
