Changes are being made to the government's no-fly list.
The Department of Homeland Security is trying to prevent a repeat of what happened this week with the Times Square bombing suspect.
Starting Wednesday, airlines are required to check no-fly lists within two hours of being notified of additions to the list. They used to have 24 hours to check the lists.
Airlines could face fines if they do not comply.
