Delta female passenger had bad allergic reaction to onions causing tongue and throat swelling

DALLAS — A Delta Air Lines flight from New York to Dallas-Fort Worth ended with emergency medical team involvement on Friday morning after a passenger suffered a severe allergic reaction at 30,000 feet.

Delta Flight DL873 departed New York (JFK/LGA) on Friday, November 6, 2026, at 7:00 AM EST, operated by a Boeing 737-800 registered as N398DA. Shortly into the flight, a female passenger seated in 1B began experiencing a severe allergic response to onions, marked by rapidly progressing swelling in her tongue and throat.

As the passenger’s symptoms intensified, the flight crew quickly established communication with a ground-based medical advice team to monitor her condition and prepare for assistance upon landing. The passenger was carrying an epinephrine auto-injector (EpiPen), though officials have not yet confirmed whether she administered the dose during the flight.

Despite the medical emergency onboard, the aircraft proceeded safely to its destination. The Boeing 737 landed normally at Dallas-Fort Worth International Airport (DFW) on runway 35 before taxiing to Gate 15 at Terminal E, where medical personnel were on standby to evaluate and treat the passenger.
