LAREDO, TEXAS (KGNS) - Passengers on a flight to Laredo made it to their destination some four hours late, following an unplanned stop.
Travelers on an Allegiant Air flight from Las Vegas were due back around 7 p.m.
The 162 passengers stopped first at Phoenix-Mesa Airport in Arizona.
A spokesperson cited an apparent mechanical problem, discovered mid-flight.
Crew "encountered a mechanical issue with icing equipment shortly after take-off," read a statement from a representative for Allegiant Air.
"It felt like there was a problem with the engine. But we didn't really think about it until we got a little higher and it started shaking more and more. And then they told us there was a problem," said passenger Jorge Luis Pineda after arriving to Laredo.
"I just heard the captain and he told us that there was a problem with one of the engines, and we're going to make an emergency stop in Mesa, so we stayed there like a couple of hours, said Alex Villalobos, another passenger.
An airline spokesperson said the plane was not having an engine problem.
They said the stop was not an emergency landing, but a precaution.
