Oakland is a nice small airport. Getting through security was a breeze with TSA precheck. We did have to stand in line for about 20minutes to drop bags as there were no agents at the counter. I had the most delicious crispy Al pastore taco near face 14

Be patient. Get there early. Ignore the crazies in LAX.

The delays we experienced on both flights to and from were cancelled or delayed which made for a very stressful trip. I would suggest monitoring the flight status continuously before arriving at the airport.

I prefer this airport over LAX. It is manageable, and one only needs one to one and a half hours of preflight arrival.

Pay extra for the carry on and we got to board 1st. I did not pay to sit together but when I checked in the day before we were all 3 together.

It is a very crowded flight, so I advice to choose seats in advance. We didn’t have that option and that was the only complaint I’d have because they put us in the middle seats and we both wanted aisle seats. My sister was able to switch but I wasn’t. She was switched to the back, almost to the last row.

Finding the gate was easy. Burbank food kiosk were extremely expensive. Cost $21 for 2 parfaits. Take your own snack foods.

Use express baggage label print outs for your bags. TSA is quick and usual grumpy demeanor.

Arrive early. May want to pay for the upgrade to a better seat. Early boarding is best.

SeaTac is a terrible airport. Getting to and from boarding areas is like going on an expedition. Signage is not clear and we and several other passengers ended up walking around in areas that were poorly marked.
