I believe the Texas law allows citizens to sue anyone who helps her get the abortion, so conceivably an airline pilot or bus driver or a significant other who drives her, could be sued. They can't stop it after she leaves the state, but they can retaliate against anyone who helps her.
This stupid law has not been tested in court yet. It seems destined for the Supreme Court in the end, which I bet rules against it, because it's awarding damages to random people who have not been damaged
It would be interesting if she used a major corporation. I know no non-public info but let's say she got a flight on American Airlines.
The Texas government suing American Airlines in a civil case(both parties have an army of lawyers and funds to defend themselves) over this would probably set legal precident.
I don't agree with the law, just stating that the resulting suit would be interesting to follow.
