Frontier suspends pilot in connection with social media comments on transgender student

(CNN) -- Frontier Airlines has suspended a pilot over Facebook comments he is accused of making about a transgender student, officials said Monday. The posts were among several that led a rural Oklahoma school district to close for two days last week.

The pilot, who was not identified by the airline, was suspended August 13, a day after the airline said it learned of the comments about the seventh-grade student made in a Facebook group for parents in the Achille Public Schools system.

The airline did not say if the unidentified pilot was a parent in the district, which is southeast of Oklahoma City. Frontier officials are investigating.

"Frontier Airlines prides itself on setting an example as a respectful workplace and we do not condone discrimination. We have long-established standards of conduct, to which all employees must agree to adhere, that among other things require people to act in a professional manner and to treat each other with genuine respect and kindness, the airline said.

The incident started when the transgender student used the middle school girl's bathroom this year,
