Many passengers getting off Southwest flights at Philadelphia International this weekend say they had no knowledge of the emergency landing or why several flights were delayed:

Passenger: “I was very surprised. But I didn’t ask and I didn’t know why.”

Reporter: Is this the first time you’re hearing about this?

Passenger: “Yes, this is the first time, I heard someone talking at the baggage claim, but I didn’t know what they were talking about.”

John Abom arrived in Philly on a flight from Tampa and says there’s a bright side to the Southwest scare, “It’s a good wake up call because it’s going to remind all the airlines that they need to check.”
