Terminal 1

Security lines in Terminal 1 can hit 30–40 minutes at peak.

Terminal 1 at SAN is the older Southwest/Alaska side, and it feels it. Southwest runs most of its flights from here, with Alaska also using the gates along the single concourse. Space is tight, ceilings feel low, and seating fills fast once morning banks start around 6:00 a.m. If you can pick Terminal 2 instead on SAN routes, do it.

TSA PreCheck at Terminal 1 often saves 15–20 minutes.

Regulars with PreCheck consistently report shorter lines at the Terminal 1 checkpoint, especially between 5:30–8:00 a.m. and late afternoon around 4:00–6:00 p.m. The standard line can snake back toward the ticket counters, and one local guide calls it “very long” on busy days. If you land in T1 and need to walk to T2 for a connection, add 30 minutes for re-clearing security during those windows.

Pre-security seating in Terminal 1 is limited to a few small clusters.

Before security, you get only a handful of benches near the Southwest and Alaska check-in zones, and they fill up fast when lines build. One guide calls out “VERY few seats before going through security,” and they’re not exaggerating. If you’re early by more than 90 minutes, you’re better off checking bags and heading straight through screening rather than trying to camp in the ticketing hall.

The walk between Terminal 1 and Terminal 2 takes about 10 minutes outside.

There’s no sterile connector; you exit Terminal 1, follow sidewalk signs along the curb, and re-enter through Terminal 2 security. That 10-minute walk is realistic with a rollaboard, but early-morning crowding can add 20 minutes or more at the T2 checkpoint. Flyers chasing better food, quieter seating, or airline lounges in T2 factor in at least 30 extra minutes door to door.

Food in Terminal 1 clusters near the main airside concourse bend.

Post-security, you’ll see Jack in the Box and Dunkin' first on the concourse, both usually open from around 4:30 a.m. through the last departures. Down the way, the small food area collects KFC, Sbarro, Subway, and Rubio’s Coastal Grill, plus an Einstein Bros. Bagels stand for bagels and coffee. Compared with Terminal 2’s bigger mix, this is thinner, which is why locals often eat before getting here.

Rubio’s in Terminal 1 is the go-to for a hot meal under $15.

Regulars mention Rubio’s burritos and fish tacos as the best bet if you want something that feels like San Diego, with combo pricing usually landing in the $10–15 range. For fast calories, Jack in the Box and KFC move lines faster but lean heavy and salty. Sbarro slices sit under heat lamps; grab a piece only if your gate call is under 20 minutes and the line is short.

Dunkin' and Einstein Bros. carry most of the early-morning load.

On 6:00–7:00 a.m. departures, expect a line at Dunkin' stretching 10–15 people and a similar queue at Einstein Bros. Bagels. Coffee prices sit around $3–5, with breakfast sandwiches in the $5–8 range. If your boarding pass shows group C or later on Southwest, hit coffee first, then hover near the gate; seating around those early Southwest gates fills quickly and people start lining up 30 minutes before departure.

Hudson News and Tech Showcase cover basics and last-minute cables.

Hudson News in Terminal 1 sells standard magazines, snacks, and bottled water, with water typically around $4 and grab-and-go sandwiches around $9–11. Tech Showcase nearby carries headphones, phone chargers, and power banks, which helps because outlets near some of the older gates are scarce. Grab a battery pack here if you’re headed to one of the end gates where wall plugs run out fast.

Terminal 1 has no airline lounges and limited quiet corners.

Unlike Terminal 2, there’s no dedicated lounge space or airline club in Terminal 1 for Southwest or Alaska. Most seating is at the gates themselves, and on peak days every seat can be taken from roughly 7:00 a.m. onward. If you need quiet, walk toward the less-used end gates and look for empty rows opposite the boarding doors; they’re often the only semi-quiet spots.

Regulars eat and charge up before coming to Terminal 1.

Frequent SAN flyers often grab a meal in the city or at hotels along Harbor Island Drive, then arrive at Terminal 1 about 90 minutes before flight time with PreCheck or two hours without. Some even plan connections through Terminal 2 when possible to get better seating and food options there. If you’re stuck in T1 for a while, claim a plug and a seat near your gate early; by the 30-minute boarding mark, both are scarce.

One practical tip: build a 20-minute buffer for lines and food.

At Terminal 1, add at least 20 minutes on top of whatever you’d normally plan at a small airport: 10 minutes for potential TSA slowdowns and another 10 for food or a restroom stop near your gate. If you’re moving between Terminal 1 and Terminal 2, tack on the full 30 minutes. Build the buffer and you’re not eating Sbarro in the boarding line.
