Oops my bad sorry
I see it now

Does anyone have any accurate software that shows jetways? Then I can test my theory

@Insertusernamehere. MaxSez: Pull up any Sectional, WAC or Hi Altitude Chart. The airways are clearly marked as Victor or Jway’s, in some cases color coded.
airnav.com is an excellent source, Regards


Done some extremely thorough testing and can confirm the higher the altitude of the airway, the more white it is, and the lower, the more gray it is.
