After a transcontinental cruise , I decided to fly home from Ireland. When I was researching flights to return to the States, I noticed that airport taxes vary depending on which country you depart from. Dublin, Ireland was one of the least expensive. When booking with British Airways, you also have an option of a stopover. This means that you may stay in another country for a length of time and then continue on with your journey at no extra cost. This is all on a single ticket. This allowed me to break up my long day of flying and see a small part of Dublin.
