Use the Princess site. Do a search for a similar cruise area and similar dates. Pick one that departs close to the HAL cruise you have in mind. When you get to the details page, click on Airfares. It will suggest your arrival airport close to the Princess cruise. For example, if the Princess cruise leaves from Barcelona, you can use the pull-down and select Rome or some other city. Princess and HAL use the same airfare search engine, so you can get a rough idea what your air cost will be.
