Severe weather caused major flight delays and cancellations at Denver International Airport over Memorial Day weekend, stranding travelers during one of the busiest travel periods of the year.

One of the many passengers, Becca, shared the footage of standstill queues for the airport shuttles.

Dense fog and thunderstorms led the FAA to issue a temporary ground stop, halting all flights for about an hour.

It was the second major disruption at the airport that weekend, highlighting the urgent need for upgraded air traffic control systems.
