Originally when I found out about SFO development, I was hoping for the jetways to be animated. That did'nt end up being the case but I still ended up buying SFO for the simple fact of being a United Airlines Hub
. I have AES however have not used it in some time and waiting for newest version. I have wanted to buy FT's Midway International Airport but I have waited for a bit longer until SFO is covered by AES. 
That is true, I can see that you are big United fan
. But thank you for your input, and yeah I did see the post that AES's next version was going to cover it, but I don't have AES and because of GSX, don't plan to get it. How much does it cost for credits? I hope that the main Flightbeam guys will come to their senses about jetways for KPHX. KSFO looks gorgeous and I hope that with that quality for KPHX, if they have "good jetways" I will definitely buy it.

For me the jetways aren't a big deal whether they move or not. If they do great, and if they dont its not a big deal to me, but I wouldn't let one little detail of an airport that looks 1000% better than default stand in my way.
But, if moving jetways were a big deal to me and I was trying to device whether to by KSFO I would look at it this way:
a. Keep the horrible looking and not so great performing stock FSX KSFO, but have jetways that move
or
b. Get a GREAT looking KSFO that performs better than the stock version, but has no moving jetways
For me the answer is easy, option B, but if your really into moving jetways then I guess A would be the only way to go, or wait who knows how many years for another sim and version of KSFO to come out that has them, or buy AES. Personally I have always though that anyone who lets moving jetways determine if they buy or dont buy an airport is really missing out on some great airport sceneries, especially if the only other choice is to stick with default, which is usually the case.
