I’m not sure what you’re asking, but I would get the exact price. It says “$430 and up.” It’s the “and up” that has me worried. Sometimes that’s only out of a certain airport. It also depends on your dates. You can sometimes find those kind of deals if you’re traveling in the off season. I just returned from Germany and paid approximately $800 BUT I was traveling at peak season. In the spring they were offering rates about what you’ve found here.
Just be careful and make sure you look at all the restrictions – see a previous thread about costs to change your ticket – and specifics to the ticketing process.
