If you're stuck in a flightmare, you're not alone.

Hundreds of flights were canceled across the US on Friday as the ongoing government shutdown sparked air traffic controller shortages nationwide.

American Airlines, Delta Air Lines, and United Airlines are among the airlines most severely affected by the cancellations. Major flight hubs, such as Atlanta, Chicago, and Denver, faced hourslong delays and cancellations.

It's all because air traffic controllers — who are working without being paid while the government remains shut down — are calling out sick. The high-stress profession was already facing shortages across the country long before Congress couldn't reach a funding deal. And now, Transportation Secretary Sean Duffy has suggested that the federal government could cut even more flights if the shutdown continues.

Until the shutdown ends, travelers are caught in the middle. And Business Insider wants to hear from you.
