It’s a long way to Mexico, Central America, and South America. If you want to do a mass deportation of all the estimated 20 million illegal immigrants, you’re either going to send them by plane or boat, or some mix of the two. You could contract a fleet of cruise ships. The largest cruise ship in the world is Royal Caribbean’s Harmony of the Seas, which can carry 6,780 passengers. You could also contract a fleet of Airbus 380 commercial aircraft, which can carry 853 people in an all-economy class configuration.
I suppose there are other options if you want to send people back like cattle. You could, for example, use the massive oil tanker ships. You could also use those huge C-5 Galaxy military transport aircraft.
But assuming we wish to be somewhat “humane” about the process, let’s go with a mix of cruise ships and A380s. Let’s go with an average of 5,000 passengers per cruise ship and, say 850 per A380. If you only used cruise ships, you would need the ships to make 4,000 roundtrip cruises down the Gulf of Mexico and the Caribbean Sea or down the Pacific Ocean. If you only used A380s, you would need the aircraft to make 23,529 roundtrip flights. So, about 2,000 roundtrip cruises and 11,765 roundtrip flights should just about do the job.
So, how long do you reckon it would take? And how much would it cost? Well, I guess it depends on how many ships Royal Caribbean and other cruise line companies, as well as airlines are willing to spare. Costs will depend on what kind of price deals we can negotiate, and of course it will depend on fuel and maintenance costs. You also have to feed people. Oh well, we can work out the details later. Of course, you first have to find them all and house them somewhere while they’re waiting to board. That’ll be a sight.
