Travelers flying out of Chicago's Midway International Airport encountered extremely long lines to pass the TSA checkpoint on Thursday.

One user shared a clip of the scene on YouTube, which is above. Warning: There is some foul language in the clip... although it's about what you might expect from travelers encountering this situation at an airport.

Travelers reported delays going through security throughout the day, and some shared images on Twitter:

ABC 7 Chicago reported that it took travelers about an hour to make it through the line, although on social media some said it took closer to two hours.

The lines returned to normal by about 10 pm on Thursday night, ABC 7 said.

Last week, the TSA warned travelers to expect extensive delays this summer due to poor staffing.
