As with most major airports in the US a good rule of thumb is to MCO 3 hours before an international flight and 2 hours for a domestic flight. That said a study in 2019 by Bayut found that MCO security wait times were the worst of any of the big US airports, whilst Finance Buzz ranked it 4th worst in 2020. If you have an early morning flight you may want to consider arriving earlier for your flight than the guidance above as these are the busiest times, whilst later in the day has the shortest security lines.
Above you will find which TSA PreCheck lanes are currently open at MCO. Given the reputation for long security wait times at MCO it would be well worth considering TSA PreCheck membership if you are a regular traveler.

Unfortunately, MCO TSA wait times can be long, often multiple hours. Like a lot of busy US Airports Orlando can provide people's first experience of the US with a miserable wait to get processed before getting out of the airport. Many people do report a quick passage through the airport but various factors including how many other flights are arriving at around the same time as yours can make MCO wait times vary greatly.
