We will be leaving from MCO on Monday. Our flight leaves at 3:30. Everyone has precheck except for my 72 year old father. First, are they lines for security bad in the afternoon like I have seen in posts? Second, should I get him a free trial of Clear? He is easily confused and does not travel often. It’s probably been at least 10 years since he has been on an airplane. Thoughts on the best way to handle this situation.
