Hi, I'm taking a trip to Guam in March to visit my boyfriend who is stationed there. I'm planning on doing the "name your own price" because I can't find anything cheaper than 1800 and I am flexible with layovers and connections, as long as I get there. My question is when I am entering in my departure airport, if I enter in DCA, the taxes on the next page are 600 dollars! The same goes for IAD, but when I enter in BWI, the taxes are 117. Can anybody explain why this is? 600 dollars in taxes is crazy! Thanks :)
