Jetblue Question

Does anybody know how I can get a breakdown of the taxes that I am paying on Jetblue?? My brother lives in the DR and is traveling for business on Jetblue. He tried to get an idea of how much the DO taxes were, as his controller wanted to have an idea of how much the taxes would be, but the local Jetblue office told him they were unable to give him a breakdown and when he called the 1-800 number, they were not able to identify the DO tax

I wonder...are they charging this tax on the ticket?? Is my brother going to get charged at the airport the date of departure??

Thank you Erin...I was able to speak to some gentleman at Jetblue's Airport Office and he explained that the DO tax was included in the fare, instead of the tax line on the breakdown. Thank you anyway!!
