Americans' travel plans continue to be impacted as airlines nationwide are canceling and delaying flights amid the ongoing government shutdown.

Airlines canceled 1,700 flights Monday and almost 1,000 for Tuesday. The Associated Press reported that some air traffic controllers, who aren't being paid, have stopped showing up to work.

Controller shortages resulted in delays of four hours at Chicago O’Hare and 45 minutes in Las Vegas on Monday.

According to the AP, the FAA warned of staffing problems at over a dozen towers and control centers that may result in more disruptions in cities including Philadelphia, Nashville and Atlanta.
