Macbook Air has dual band wifi-n radio. I want it to use non-congested 5 Ghz band but keep 2.4 Ghz as a backup. Often times it switches to 2.4 Ghz. Is there a way to force it to use 5 Ghz?

Pretty sure in the Wireless settings on the mac where it remembers all of your networks you have previously joined.
You can re-arrange the list and it priorities them from top to bottom.

to do this you need to set differenet ssids for bands and adjust the priority in osx's internet setting

Thanks, moving the 5G connection to the top of the list was the solution.
