A Colorado Springs flight bound for Las Vegas was diverted back to the airport shortly after take-off Thursday morning after the plane's smoke alarm went off, airline officials said.

Allegiant Air Flight 559 was forced to land after haze and smoke was reported inside the cabin, said Allegiant Air spokeswoman Lindsay Hernquist.

The plane, a McDonnell Douglas MD-83 twin-jet, departed around 10:45 a.m., and landed safely back at the airport at 11:06 a.m., according to flightaware.com, which tracks flight activity nationwide.

The smoke dissipated once the plane made it to the gate and turned off the engine, Hernquist said.

Passengers were loaded off the plane and provided food, a $75 voucher, and a chance to change their flight for free, she said.

The plane holds 166 passengers and 6-crew members, Hernquist said, but the amount of people was onboard was not immediately known.

Officials are still investigating the cause of the smoke.

A plane from Phoenix arrived several hours later to take passengers to Las Vegas, Hernquistsaid.
