You just never know how long it will take to pass through security. Using this airport often, sometimes I have been in the security line for 45 minutes. At other times it has taken me less than 10 minutes to get through this area. Holidays are expecially bad. Also the morning flights from around 7am-9am and the evening flights from about 3:30pm until 6:30pm or so.
I know a number of folks who have missed their flights because they did not allow enough time for this stage of their flight.
Forewarned is forearmed as they say.
