SANFORD, Fla. – Pilots for Allegiant Air are raising new concerns about the safety of the company's planes.
The pilot's union has sent the airline's board of directors a letter, outlining its concerns.
In part, it says: "As you know, the pilots at Allegiant Air have concerns about the company's bare minimum approach to maintenance and operation of the airline."
The letter goes on to say: "Allegiant is continuing to cut corners on industry standard practices, including ignoring FAA recommendations on running important safety programs."
The letter follows a big scare for Allegiant.
Earlier this month, in Clearwater, one of its jets had to make an emergency landing after smoke appeared in the cabin.
Just this week, another Allegiant Air jet landed at the same airport with pressure problems.
Officials with the union say it's just one of dozens of problems in recent months.
Airline executives say the pilots are upset about ongoing contract talks.
