If my organization is tax exempt does that also apply to airline tickets?

There are numerous taxes or fees added to each airline ticket. No one is exempt from the taxes and fees imposed on domestic tickets. Eligible government employees are exempt from three fees on international tickets: US Customs Fee of $5.50, US Immigration and Naturalization Fee of $7, and US Animal and Plant Health Inspection Service (APHIS) Fee of $5, totalling $17.50. Eligible travelers must present a copy of their diplomatic identification card and/or their A-1, A-2, G-1, G-2, G-3, or G-4 visa when purchasing airline tickets.
