"However 90 minutes into the flight, the pilot told Mutlu the flight attendant was uncomfortable and he would have to give up his seat and "hang out" in the bathroom for the remainder of the flight, the lawsuit said.

"The pilot "became angry at (Mutlu's) reluctance" and said Mutlu "should be grateful for being onboard," the lawsuit said. When Mutlu volunteered to sit in the "jump seat," he was told it was reserved for airline personnel.

"At one point, the airplane experienced turbulence and Mutlu sat on the toilet seat without a seat belt, causing him "tremendous fear," the lawsuit said."
