Thank you for contacting the airport. The recommendation per Allegiant and TSA is that you arrive 2 hours before flight departure. Processing through the TSA line depends on many factors and recommended that you follow their guidelines.
Plan on 30 minutes. You may inadvertently have something that they don't want you to take, this process adds time going through. Line or no line.
Usually really quick but it depends upon the line if the lines long it may take up to 20 minutes
