We used Disney to book our flights when we travel overseas. Anything comes up, they will do their best to get you to the ship and get you home from the ship should there be issues. There is not much of a difference in cost, for us. We fly out of Boston and their rates are good. You can also suggest to them airlines or rates you see and they can try and book. Domestically, I can handle that on my own. Transport I use depending on what my plans are. Overseas I use them especially when the port is far from where we are staying- I want to make it to the ship and I want to make my flight. Domestically I may use them one way, once again depending on our plans. These days it is just the two of us, so renting a car or private transport isn't always the most economical.
