Indiana is taking the unprecedented step of banning travel from several states in the Midwest and South for the first time in its nearly 200-year history.
Travelers from Texas and Mississippi will be allowed to board U.S. airlines beginning Jan. 1, 2018.
Indiana, Kansas and Kentucky have already passed similar measures.
Travel restrictions have been the subject of fierce debate across the nation, but they have been blocked in several states by courts and congressional majorities.
Indiana’s ban has a 90 percent chance of surviving a constitutional challenge, according to the Associated Press.
In addition to Texas and South Carolina, Indiana has allowed flights from Georgia and Arkansas, two other states with heavy U.s. air travel.
It is also allowing flights from New Mexico, North Dakota and Iowa.
