Travelers at the South Bend International Airport should expect longer wait times as new 3D scanners get installed at TSA checkpoints.

While those new scanners are being installed only one screening lane will be open for passengers with carryon bags until Friday, so travelers are encouraged to check their bag if possible to get through the line easier, and arrive at least two hours before their flight leaves.

The airport has also opened at 3:45 am to allow enough time for travelers heading out with morning flights.

The installation of the new machines is expected to be complete Friday afternoon and normal operations to resume are expected to resume Saturday.
