I have a late meeting at DFW and then I'm flying out on AA at 6:00 am the next morning (with only a carry-on). According to the TSA site, DFW's latest security checkpoint closes at 11:30 pm and then the earliest one opens at 3:00 am. In the unlikely event my meeting gets done before 11:30 pm, is there any chance TSA will let me in around 11:30 pm with a next-day 6:00 am boarding pass? Thanks.
