Chick-fil-A in both halls

T2 evenings and T4 mornings are the long lines
Official OIAA peak windows are Terminal 2 04:00–07:00 and 19:00–23:00, and Terminal 4 05:00–09:00. TSA says under 20 minutes off-peak and 30+ when a bank hits.
Pick T2 or T4 before you clear TSA
There is no post-security walk between Terminal 2 and Terminal 4. A covered landside walkway links them; changing terminals means reclearing.
Chick-fil-A is in both halls — closed Sunday
Official dining lists Chick-fil-A at Terminal 2 Gate 206 (opened Jun 2026) and Terminal 4 Gate 405, plus Brewery X in both terminals.
