Flight from Ontario to Austin

PAULFlew with Southwest-Oct 2026

You likely don't have to pay to check a bag since SWA always asks for volunteers to check bags for free at the gate.

JulianFlew with Delta-Jun 2026

Be prepared for new screening processes including dog sniffing. You're asked to walk in group of 2 for about a 15 foot stretch while a sniffing dog follows just behind.

Verified travelerFlew with Alaska Airlines-Dec 2025

Bid on an upgrade seat if you can, I was pleased with my upgrade.

CarlosFlew with Alaska Airlines-Jun 2025

Get to the San Diego airport early. The security line will be long. Also, if you're flying Alaska Airlines and don't check in online, go to the Alaska Airlines "Agent Assit" counter first. Don't be like me and go to the Alaska Airlines "Bag Drop" line. That was a bit confusing. If you're flying Alaska Airlines.

Verified travelerFlew with Alaska Airlines-Jan 2025

Use the lounge access at the discounted rate. It was very nice.

Verified travelerFlew with Alaska Airlines-Mar 2024

If veteran or active duty, make sure to stop by USO in terminal 2 (SD airport); right next door to Alaska departures.
