My overseas flights are almost always on 747's. I like that airplane. I fly mostly United on those.....United is ok, but I prefer Singapore Airlines or even Cathay Pacific. BA isn't too bad, I guess, but the Asian Carriers know what service is all about. SwissAir is ok too...took them from Karachi to Dubai and then to Zurich and finally back to Boston.
Once though I had to fly from Karachi to Lahore and you can only use Pakistani Air....freaking scary!
On the leg out to Lahore, I was on a 747 that still had the circular staircase to Business Class in the upper deck. Interior knobs weren't working, all kinds of stuff. Plus, and I apologize to Straffo, but before we left the gate a French business man was making a scene because he bought a business class ticket, but there were no seats left there when he boarded. Long story short, they took him off with armed guards....scared the crap out of me.
On the way back to Karachi, I flew on an Airbus. Brand new...was really nice. I draw the comparison not because of manufacturers but because of how Pakistani Air maintained their fleet.
Now I did refuse to fly from Shenzhen to Shangai once because it was going to be on China South Airlines.
Thai Airlines is ok....used to fly them from Bangkok to Sri Lanka a few times.
I fly mainly to Europe these days....to Brussels of all places....and yes Saw has been my tour guide once......just once..hehe. I fly United for that and I think they use Boeings..777 or 767 maybe. Very nice airplane. I use American for my Mexico City flying, but after my last trip, I'm thinking of switching to Continental.
My wife used to fly Alitalia alot when she would go back to Italy to visit her family. She said two things about them....They Never EVER left on time, but the food was pretty decent.
But the BEST by far Domestic airline for me is Midwest Express!!! Especially when they used to have the meal service and those chocolate chip cookies. If you ever have the chance to fly Midwest Express, you should absolutely do it. They us an MD designation airplane, I believe.
EDIT** Oh and one airport I don't ever want to have to fly into again is Roanoke. Was on a turbo-prop into there about 2 years ago, and the winds were blowing about 30 mph in that bowl were the airport sits.....Holy crap was that a ride to the runway....we hit turbulence so bad that my head hit the overhead compartment, and a lady a couple of rows ahead of me kept screaming that the pilot was trying to kill us.
An airport I wish would still be in service is the old HK airport...man that was fun flying between apartment buildings seeing people hang laundry on the approach to landing.
