Flight 1544 took off from Newark around 6 a.m. Tuesday and was headed to Las Vegas, but quickly had to return to the airport.
Everyone got off the Boeing 757-200 safely and the passengers successfully took off again in a different aircraft around 10 a.m.
There is no word yet on what caused the issue.
The FAA will investigate.
The incident comes the same morning that a Southwest flight had a close call with a business jet at Chicago Midway Airport.
