Every time I fly frontier something happens. Last time I flew there was a fight at the gate. Shouting and cursing with kids all around. This time the flight wasn’t full so they allowed us to move seats if we wanted for more space. One guy moved to an exit row and was told he can’t sit there unless he paid extra. That started a fight between him and the flight crew. they called the police to remove him. Last year in NY there was a fight at the gate between the agent and a passenger. Always frontier airlines I’ve never seen this with any other airline. I would never bring my small children again who knows what could happen. Flight was also delayed coming back to Orlando. You get what you pay for with frontier.
