Our PP paid for itself on our first trip. In-country flights from Cuzco to Lime are early AM to get the denser morning air. International flights from Lima leave around midnight. We were too fagged from travel to do much sightseeing in Lima. Spending our hours on a leather sofa instead of a hard plastic chair was a Godsend.
When me bride was on the road a lot my gift of a PP to her worked great. Now that we travel together a lot, my membership is piggybacked on hers.
PP coverage of USA airports is so-so. But overseas it is great!
