MaryFlew with Alaska Airlines-Apr 2026
If any one has a hard time walking long distances automatically ask for wheelchair assistance the person helps guide you to your gate and there is a lot of walking
AdamFlew with Alaska Airlines-Mar 2026
SNA airport is easy to navigate. Always quick line at security.
Verified travelerFlew with Alaska Airlines-Feb 2026
Purchase one of those luggage covers because your bag might end up being checked regardless. Download episodes before your flight because they don’t always offer in-flight wifi.
Verified travelerFlew with Alaska Airlines-Feb 2026
Make sure you have a REAL ID and not just a drivers license. It’s a $45 fee to get it processed the TSA rep told me.
Verified travelerFlew with Alaska Airlines-Jun 2025
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
PaulFlew with Alaska Airlines-Mar 2025
Be patient. Get there early. Ignore the crazies in LAX.
MargaretFlew with Hawaiian Airlines-May 2025
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.
CherylFlew with Alaska Airlines-Oct 2024
I prefer this airport over LAX. It is manageable, and one only needs one to one and a half hours of preflight arrival.
TerrieFlew with Spirit Airlines-Oct 2024
Get there early just in case there’s traffic’s
SaraFlew with Spirit Airlines-Aug 2024
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.
Verified travelerFlew with Alaska Airlines-Jul 2024
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.
Verified travelerFlew with Alaska Airlines-Jun 2024
Finding the gate was easy. Burbank food kiosk were extremely expensive. Cost $21 for 2 parfaits. Take your own snack foods.
Verified travelerFlew with Alaska Airlines-Jun 2024
Use express baggage label print outs for your bags. TSA is quick and usual grumpy demeanor.
crd041678Flew with Alaska Airlines-Apr 2024
Arrive early. May want to pay for the upgrade to a better seat. Early boarding is best.
Verified travelerFlew with Alaska Airlines-Mar 2024
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.
