NEW ORLEANS, LA (WVUE) –

The FBI is investigating what it calls a credible bomb threat made against a Delta Airlines flight Saturday traveling from Portland to Atlanta and one made in reference to a Southwest Airlines plane going from Minneapolis to Atlanta. Both planes have now been cleared and deemed safe but it caused a tense few hours for travelers.

At Atlanta’s Hartsfield-Jackson Airport, a bomb squad and dog unit met both planes after they were escorted in by military aircraft.

Rachel Gontowski, who was traveling from Atlanta to New Orleans, says, “They were just taking people off one by one.”

Authorities say the threats were made on Twitter, with one reading, “A bomb will be detonated at a random time of my choosing. Strongly recommend you don’t try anything stupid.”

Southwest flight 2492 was already scheduled to stop in Atlanta once it left Minneapolis. Then it was to continue on to New Orleans. Passengers booked on the flight from Atlanta say they initially didn’t know about the threat while at the airport, but they quickly figured out what was going on.

“All the information we got was through social media basically,” said Victor Tavares.

Some were too scared to board. Vanessa Roggia explains, “The plane was less than half-full. There were tons of empty seats, a lot of people at the Atlanta airport were like there’s no way I’m getting on this flight. A lot of people left.”

Although it still bore the same flight number, the airlines switched out the planes. The one the threat was made against still sits in Atlanta. The FBI says both the Southwest plane and Delta aircraft have been cleared and did not have any explosives on board.

After landing in New Orleans, passenger Troy Williams said, “I’m glad to be here safe. I’m glad they caught that, acted on it.”

Now, the investigation into who sent the threatening tweets is underway.
