The length of the security queue at MCO (Orlando International Airport) can change based on a number of variables, including the hour of the day, the day of the week, and the number of passengers. Passengers may have to wait longer at security checkpoints during popular travel times, such as holidays or the summer. But MCO security wait times has taken steps to speed up screening, like using cutting-edge technology and specific TSA PreCheck lanes, which help shorten MCO security lines for qualified passengers. Travellers should give plenty of time to go to the airport in case there are any delays at the security checkpoints.
