The flight had just taken off from Philadelphia International Airport and was headed to Seattle when unburned fuel burned off, a spokesperson said, explaining that such occurrences are not uncommon.

The 133 passengers on board were put on a different flight.

 

Earlier in the day, a Delta-operated SkyWest plane caught fire in Nashville.

The plane was on the tarmac at Nashville International Airport at the time of the incident.

Airport spokeswoman Shannon Sumrall said in a statement, “The auxiliary power unit caught fire but when they turned the engine back off the fire extinguished itself and the plane was brought back to the gate and all passengers were de-boarded."
