Ex-WWE Superstar Matt Riddle seemingly had a few too many drinks during a plane delay earlier this month ... grabbing a microphone and shouting at fellow passengers -- and TMZ Sports has the video.
The incident went down at JFK Airport on September 9 ... the same day the two-time Raw Tag Team Champion accused a Port Authority police officer of sexual assault, which led to an investigation.
Our video shows what went down prior to the allegations.
A witness tells us their flight to Orlando was postponed multiple times, so Riddle and his friend waited it out by enjoying drinks at a nearby restaurant.
