Bauer said the passenger began to film just after the pilot asked passengers to refrain from discussing President-elect Donald Trump or other hot-button political issues while in the air.
"I understand everybody has their opinions; that's fine," the captain says over the plane's speaker system in the video.
"If you support him, great. If you don't, I understand. However, we're out here to go to Puerto Vallarta, supposed to be having a good time, and what I do ask is that as people we have the common decency to respect each others' decisions and to get along on this three hour and thirteen minute flight so that we can have a good time when we get down there.
Nobody wants to argue, nobody wants -- nobody is going to change their minds by arguing. And let's keep our opinions to ourselves on this particular matter at this particular time.
If there's anyone that has a problem with this, that needs to vent or rant or rave -- there's another flight tomorrow. You're not going to be on this one. I hope that's clear."
The uploader said the pilot's speech was inspired by an altercation moments earlier between a white male passenger and a black female passenger. Bauer wrote the man said something "racist" related to Trump's election and "being glad to have kept his guns," causing the woman to "cry and freak out."
"The individual that said what was said to the African American lady DID apologize to her after the crew separated them on the flight," Bauer wrote.
