I am thinking of getting one, in addition the my passport book, as an easier form of ID for getting onto the ship and domestic flight. We are taking a western caribbean cruise. I understand they do not work for international air travel.
A passport card is only good for land crossings from US/Mexico, US/Canada and closed loop cruises. Your drivers license or State ID card is sufficient for domestic air travel. As you stated: You cannot use a passport card for air travel outside the US. This could be an issue if you had to fly home from a cruise. You need a valid "passport" to get home.
Unless you make a lot of land crossings to Mexico or Canada the passport card really isn't worth the extra expense.
