Official A/B TSA portals generally open by 04:00 and close with the last departure. TAA says 90 minutes is usually enough; 2 hours for 06:00–08:00 weekday departures and holidays.

B is first on the inbound roadway (Alaska, American, Delta). A is east (Southwest, Sun Country, United). You cannot walk between A and B without reclearing.

Official B-gate pins: El Charro Café 05:00–last departure, Beyond Bread 04:30–17:30, BUILT Custom Burgers 10:00–18:00. Landside Barrio Brewing (ticketing) is 07:00–17:00.

A-side official pins: Dunkin’ near A1 04:00–15:00, Empire Pizza 10:30–18:00. Arroyo Trading Post on ticketing is 04:15–19:00 with coffee and sandwiches. Bag-claim food is vending machines only. Trust flytucson.com/in_the_terminal/restaurants_shopping.php, not a 2017 vendor blog.
