several states are trying to change that. laws are being proposed to ban travel, and although they are being challenged, as you said, the last word on this is not spoken yet.
and even if legal, people having an out-of-state abortion are being sued. that alone is a big restriction, because what good is a right if you don't have the means to defend yourself when that right is being challenged.
So no, there is no restriction on going to another state to get an abortion.
