DALLAS-<\/strong> Southwest Airlines (WN)<\/a> has launched a three-part solution to tackle the rising problem of exploding soda cans during in-flight service, a hazard that has injured several flight attendants over recent summers.<\/p>\n\n\n\n

The issue has been especially severe at high-temperature hubs like Phoenix Sky Harbor (PHX) and Las Vegas Harry Reid (LAS)<\/a>, where carbonated cans stored without refrigeration have burst mid-flight, creating serious safety risks for crew members.<\/p>\n\n\n\n

Southwest Tackles Exploding Can Issue<\/h2>\n\n\n\n

For years, Southwest Airlines flight attendants have faced an unusual workplace hazard: soda cans exploding during beverage service. In summer 2024 alone, over 100 such incidents were reported, injuring nearly two dozen crew members.<\/p>\n\n\n\n

According to the Transport Workers Union Local 556, the number of exploding cans is expected to triple during peak summer months.<\/p>\n\n\n\n

Unlike other U.S. carriers, Southwest historically avoided the use of refrigerated storage because it doesn\u2019t serve perishable food items. This practice left cans exposed to tarmac temperatures exceeding 110\u00b0F at major Southwest hubs, including Phoenix (PHX), Las Vegas (LAS), Houston Hobby (HOU), and Dallas Love Field (DAL).<\/p>\n\n\n\n

Once airborne, these overheated cans\u2014already under extreme internal pressure\u2014burst when opened, sometimes without warning.<\/p>\n\n\n\n

To address this, Southwest has rolled out a new three-step system:<\/p>\n\n\n\n

    \n
  1. Refrigerated Trucks<\/strong> \u2013 The airline deployed 60 refrigerated provisioning trucks in Phoenix and Las Vegas to maintain beverages at safe temperatures around 40\u00b0F.<\/li>\n\n\n\n
  2. Temperature Screening<\/strong> \u2013 Crew now use infrared heat guns to scan cans before aircraft loading. Cans above 80\u00b0F are replaced.<\/li>\n\n\n\n
  3. Training and Monitoring<\/strong> \u2013 Ground and in-flight teams are trained to identify dangerous cans, and Southwest is collecting data to define safe-loading standards based on environmental conditions.<\/li>\n<\/ol>\n\n\n\n

    Understanding the Science Behind the Hazard<\/h2>\n\n\n\n

    The root cause lies in the chemistry of carbonated beverages. Soda cans are pressurized with carbon dioxide (CO\u2082), which expands under heat.<\/p>\n\n\n\n

    According to Dr. Kate Biberdorf, a chemistry professor at the University of Texas at Austin, soda cans can hold pressure three to six times their normal load\u2014but once that threshold is exceeded, especially with minor manufacturing defects, they become \u201clittle bombs.\u201d<\/p>\n\n\n\n

    Even without being opened, cans may rupture from slight movement if they\u2019re too hot. While altitude isn\u2019t a significant factor due to cabin pressurization, the sudden drop in external pressure at 30,000 feet can exacerbate internal can pressure. This magnifies the risk if the cans have already been compromised by ground heat.<\/p>\n\n\n\n

    Long-Term Fixes<\/h2>\n\n\n\n

    Southwest\u2019s shift toward using refrigerated logistics marks a significant change in its operational procedures. The initiative will soon expand to other high-risk airports such as Houston Hobby (HOU) and Dallas Love Field (DAL).<\/p>\n\n\n\n

    While these updates are expected to mitigate future risks, in-flight drink service has already been scaled back, meaning fewer beverage offerings and shorter service windows on many routes.<\/p>\n\n\n\n

    The airline continues to monitor incident trends and environmental data to refine beverage safety thresholds.<\/p>\n\n\n\n

    Union officials suggest these engineered solutions could ultimately eliminate the can explosion issue, turning what was once a recurring safety hazard into a manageable risk.<\/p>\n\n\n\n
