Well one change I know you can make is 130.925 used to be Virgin Ops is now Alaska Ops. 131.2 used to be Alaska Ops is now quiet. Not sure if no longer used or is kept as a back up. Also I can confirm 130.95 is used by Philippines and 129.700 is used by British Airways. Also Servisair no longer exists. They were taken over by Swissport several years ago. Also I would move the United Ramp frequency 131.000 over with the other ramp frequencies. Yes that ramp control is operated by United, but so is the G Ramp Tower. A Ramp Tower is a city run ramp tower.
