USA one ways

Doing a ‘one way’ in the USA (pickup one location return another) is very popular, but the fees vary depending on which states, and car hire supplier used. e.g you can pickup and drop off in Florida for free (same for california pickup and drop off), but Florida to California will incur an extra fee of $500 +tax….unless you book with National, then only $199+tax. But then California to Las Vegas is cheaper with Dollar, at only $100, compared to $150 with Alamo. However, always choose National if doing a one way over say 600 miles, 900 kilometres, as they are the cheapest.
