It's a disturbing chain of events involving a 15-year-old girl flying alone on a nonstop flight to Bangor, Maine from the St. Petersburg/Clearwater International Airport.

Events that left the teen literally unaccompanied in baggage claim at the airport.

According to the teen's mother, Michelle Easler, she put her on the delayed flight around 3 p.m. on Wednesday, expecting her to arrive in Maine three hours later.

The Allegiant flight had trouble with its engines about 30 minutes into the flight and was forced to return to the airport in St. Petersburg.

After it landed and the passengers were being placed on another plane in St. Pete, officials would not allow any unaccompanied minors back on the new plane because of inclement weather.

According to Allegiant's policy involving transporting minors, "Allegiant will not permit anyone under the age of 18 traveling without an adult on the flight with a weather advisory".

So, 15-year-old Vanessa Easler and four other minors were left in baggage claim at the Saint Pete Clearwater Airport.

"They kicked her out and put her in baggage claim and no one stayed with her," says Easler,. "So that was a real problem for me because she's still a minor and I'm not really willing to let someone just pick up my kid at the airport and take her with them."

"They (Allegiant officials) didn't even know that my mom was even coming back to pick me up," Vanessa said. "They didn't even ask me if I called my mom. They just expected me to."

An Allegiant spokesperson released the following statement:

The flight from PIE to BGR was weather-advised for weather in BGR. While Allegiant does allow minors 15 or older to fly unaccompanied, we do not allow minors younger than 18 to continue on weather-advised flights. This is because if the flight is diverted to another city and requires an overnight stay, unaccompanied minors younger than 18 will not be able to book hotel accommodations.

We sincerely apologize for the inconvenience to their travel plans, but their safety is our top priority.
