southwest airlines san diego airport

San Diego International Airport (IATA: SDM) is Southwest Airlines’ largest U.S. hub, handling around 60 million en‑planations annually and offering nonstop service to dozens of destinations across the United States, Mexico, Canada and the Caribbean. Whether you’re flying into San Diego for a quick family visit or heading out for a weekend getaway, Southwest’s presence at SDM means you’ll experience the airline’s no‑frills, customer‑friendly service right from the start of your journey.

Tip: If you’re looking for the fastest flights, list‑up non‑stop routes on the Southwest website before you go to the airport—flight times for “short‑haul” routes (≤ 3 hrs) range from 1:30 to 2:45, making them ideal for a quick trip.


**Terminal and Gate Info**

  • Terminal: SDM is a single‑terminal airport. Southwest operates out of T1 (Terminal 1), the same as all other carriers.
  • Check‑in counters: Southwest counters are located at Concourse A (near gates 5–12). Arrive at least 30 minutes before departure.
  • Boarding zones: Gates are labeled 80–140. Southwest’s boarding groups are announced sequentially in alphabetical order of passengers’ last names.
  • Amenities: Free Wi‑Fi, an unlimited food and drink station (t‑em), climate‑controlled lounges (e.g., “Southwest Lounges” at gates 120–125), and a dedicated quiet zone for phone calls or naps.

Pro Tip: Use the “Southwest Lounge” before your flight—though admission is included with a Southwest gold or higher member status, anyone entering the lounge must have a confirmed flight ticket. The lounge offers seating, complimentary snacks, and power outlets.


**Check‑in and Security Tips**

  1. Use Southwest’s Mobile Check‑in: Download the Southwest app, check in via the app or website, and print your boarding pass at home. It saves time at the gate.
  2. Avoid Security Thrills: America’s Microwave‑Free rule allows travelers to bring all liquids through security—no need to juggle beverage containers. Remember, the non‑dozen rule (two everyday items per bag) still applies for carry‑on.
  3. National Gateway: Because SDM’s security is part of TSA Pre✓® and Global Entry, travelers with these programs can skip the lines entirely.
  4. Early Arrival for domestic flights: The airport’s staffed ticket counters close 30 minutes before departure, but Southwest’s self‑service kiosks are still open.


**Baggage Policy**

Piece of Carry‑On Checked Bag
Free 1 (≤ 56 lb, ≤ 15 in x 15 in x 25 in) 0 (but you can purchase a  up to 70 lb bag for $30 per bag)
Additional Fees None (up to 1 per passenger) $30/bag (first 2 bags)
Same-Day Upsizing Up to 0.5 lb for free if you visit a local store within 24 hrs of departure
No fees on children Children < 2 yrs travel free, with a 0 lb allowance

Practical Insight: If you’re traveling light and only need a carry‑on, you’ll actually save money because you’ll completely avoid checked‑bag fees. Southwest’s “Bags Fly Free” strategy pays for the extra service via higher ticket prices.
