Passenger says Frontier left them on a plane with ‘little to no AC’ for 1.5 hours in Texas heat, calling it ‘a serious safety concern’

For one Reddit user, a delayed Frontier Airlines flight in Texas turned into what they describe as an unsafe ordeal. Posting on the Frontier Airlines subreddit, the user, who goes by According_Present616, titled the post “Unacceptable and unsafe experience with Frontier.”

In their post on Reddit, the user alleged, “Our flight was already significantly delayed because the plane needed its tires replaced, causing the current crew to time out after exceeding their safe flight-duty limit. Throughout the delays, Frontier provided very little meaningful communication or updates, leaving passengers confused and frustrated.”

The account could not be independently verified, and Frontier’s side is not known. Frontier had not publicly responded at the time of publication.

According to the post, passengers were eventually boarded but sat on the plane for 45 minutes before being told to deplane because the airline lacked enough staff. They then waited several more hours before boarding the same plane again, the user said. “Once onboard again, we sat for another 1.5 hours with little to no AC,” they wrote. “The heat became unbearable, and I experienced heat exhaustion and had to get off the plane.”

Commenters disagree

The post sparked a debate in the comments. Some commenters said the delay was reasonable given the tire issue. One wrote, “This sucked but I imagine trying to take off or land on a flat tire would suck a whole lot more.”

Another commenter, who said they were on the same flight (IAH to DEN), gave a different account. They wrote that the AC “was on the whole time,” and said the delay involved nose gear tire documentation and that the crew gave regular updates.

When a commenter asked what exactly was unsafe, the poster replied, “In TX and in almost 100 degree weather without AC on a plane is called unsafe. It’s called heat exhaustion which can lead to much more serious problems!”

The poster said the crew timed out after exceeding its flight-duty limit but did not say which crew members. Federal rules limit how long crews can work and require rest between duty periods. For flight attendants, the FAA requires at least 10 consecutive hours of rest after a duty period of 14 hours or less, according to Simple Flying.

The poster wrote, “Delays happen, but the lack of communication, poor handling of the situation, and leaving passengers in an extremely hot aircraft long enough to become sick are unacceptable. This was a serious safety concern and I will not be flying Frontier again.”
