Insights shared by verified travelers who flew the route from Seattle to Riverside 
ReidFlew with United AirlinesSEA-LAXOct 2024
SeaTac does not have a very good or equitable system for security lines. First class passengers don’t have a TSA precheck option, while there are only 2 TSA precheck lines on opposite sides of the terminal. Highly recommend getting TSA plus Clear, as the airport heavily favors this combination, with each section of the terminal having one of these options. I almost missed my flight because the only TSA precheck line was about 45 minutes long.
LauraFlew with Alaska AirlinesSEA-LAXJul 2024
LAX is a bit of a mess. Very long walk between terminals.
LaurenFlew with DeltaSEA-LAXFeb 2024
If you have kids, bring your own screens. We were counting on the inflight entertainment and it was a definite letdown. Also, TSA Pre-check is only available at station 2, but wait times are posted at each station so you can see if it’s worth the walk.

Airline reviews

Cathay Pacific is an excellent, well-maintained airline. While I too would love to fly first, or business class, I did not. I actually had the dreaded middle seat in the middle row, and yet, since I am an inquisitive traveler, I introduced myself to my row mates and had nice chats with both until lights out. Pro tip: Bring a donut travel pillow no matter where your seat is! The flight was smooth, the restrooms clean and the staff courteous and efficient. I gave the comfort level a 4 because of the reasons listed above. The airline meals... let's face it ... it's airplane food but CP does a good job in making it as edible as possible.

I was not able to figure out how to get the entertainment. But the flight was smooth and quick.

Lots of turbulence in last 45 minutes, but captain kept us very well informed, which was a big help to a nervous flyer.

It was unexpected not to board with a jet bridge - the weather was good that day so it was not an issue. It was completely unclear what boarding group was called...there was no monitor with that info.

This flight had mechanical issues. I changed flights, which Alaska Customer Service handled beautifully. Then that flight was an hour late. I was originally supposed to land in San Diego at 730pm and I landed at midnight,

First class food and service was excellent. When I booked the ticket my outbound was automatically upgraded to a non bulkhead aisle seat which was much appreciated. However, my return was not. By the time I upgraded only windows on the bulkhead were remaining. It would have been nice if my seat was automatically upgraded within the appropriate advance time window so I didn't have to worry about it. (Not a big deal)

more time in layover in seattle because security for passport is a very long line

Flight delay. Didn’t receive seat assignments til last minute and partner wasn’t seated together

I was surprised by the lack of customer service from Alaska. While away I had a family emergency and called salsa to push my flight one day to lend family support and what I was met with by the customer service agent couldn’t have been any worse. Not only did this woman have zero compassion but she could barely contain her sheer disdain for her job but she gave new meaning to bad customer service. All I wanted was to find a way to move my flight by one day- she offered zero solutions other than to pay for a full fare new ticket. This experience has left me with never doing business with Alaska again. 👎

It was difficult because me and my husband weee seated separately not only us but other families too. Everyone asking each other to trading seats. Other then that it was good.

Only one side of the heafphone jack work. Crew was friendly and helpful.

Coach seating is debilitating, neither my husband or I can walk the following day

Great. Flight departed early and arrived early. Deplaning and baggage claim ww were quick.

They separated our seats and moved us to the back of the plane. Hundreds of dollars and thousands of miles used and this was my platinum member experience.

It was NOT pleasant. Started from checking our luggage to the last time getting off the plane. The crew was not friendly, the food was horrible and the seats were too close to each other that I got a bruise on my knee.

Late departure due to large number of wheel chair patrons. Used to having a box of snacks to select from in comfort plus. The flight attendant just rattled off what was available and asked us to pick. Felt rushed and uncomfortable. Seat was great. Prefer having the screen on the seat in front of me instead of having to pull it up from the seat side. Lots of room for my carryon under the seat in front of me.

AC barely worked on a 50 minute flight. It was very warm the whole flight. Flight was very bumpy and hard landing.

Got on the plane and then needed to deboard the plane because they didn’t have any pilots?

The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.

Rough day of travel all the way around. Wrong info given to us multiple times and mistakes in their booking making our trip 10 hours longer than planned. I’m bummed because I fly Delta all the time and love them. Mistakes happen. Just bummed that this was a rare trip our whole family was traveling together.

This was a 5 hour flight with no entertainment and with a snack being provided (pretzels and fruit bar), which are both high in carbs and sugar. Nuts would have been a better choice.

Was realllly smooth. It was delayed but we were well informed.

Good plane, crew, and flight. Boarding was a bit chaotic. Bathrooms were unacceptable. United DESPERATELY needs a new terminal at IAD.

Haven’t used United in a while. Was surprised with the free blanket and earphones. Service was great. Huge plane. 9/.row.

Delayed by 2.5hrs any longer and they would’ve had to honour their own policy for breaking their own rules and regs. Not cool, especially when I have an infant child that needs to stay on a routine and they get schedules.

They had three choices for snacks - but you could only have one - and they ran out of the dark chocolate before they made it all the way down the aisle... Packed flight - limited service.

To san Francisco it was ok. From sf to Manila it was horrible

They opened my checked bag and even though my lock was tsa approved, they loose my lock and left my bag just like that. Incompetent people, very upset about it. I’ll try to avoid traveling with united

We fly to Ecuador frequently. Checking in is usually a hassle because most United agents take some time before they can verify that my passport doesn't require a visa to Ecuador. This time the process was even longer due to the cyber attack. But she was really nice to us. So glad we brought plenty of snacks to supplement the 3 flights from SEA to GYE.

Awful, rude staff. Their abrasive comments are unnecessary. Most seek a frictionless experience and will cooperate if you ask. Additional childish bullying of customers is not acceptable or tolerated. We had the same problem with our departure flight. We will never fly United again.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

RE Food: Wish there was a choice for No Rating. Flew from Honolulu to Los Angeles on a Red-Eye flight (11:00 pm to 7:30 am). Other than a package of cookies with a beverage choice offered soon after take-off, and a beverage choice shortly before landing, no other food choices were offered. Everyone slept or rested for most of the trip. Nothing to rate. RE Entertainment: Everyone was sleeping most of the flight. Only saw one passenger watch about 30 minutes of entertainment on his iPad. I never attempted to access any entertainment options.

Baby cried a lot. Nothing anyone could do about it. Just part of flying.

For coast to coast travel the A321 and even the NEO, even in first class will never be excellent. That would take a B787 or 777 to accomplish.

Experience was fine. Seats were cramped, and we had to wait for repairs before we could take of. Even though the door remained open, we were warned that leaving the plane could cause difficulty trying to fly out later. Staff was pleasant, and climate control was fortunately working. We had trouble at the DFW terminal, but I don't think that was AA's fault.

The flight crew was fantastic! Which the seats had a small TV.

The foot ottoman cushion was missing on my business class seat.. the hydraulics is on its last leg & seat cushions do not have support or paddling. Heavily dented by butts

This flight was fine but had no time to breathe as the connection was late from Sea to ORD.. Super stressful. If we checked bags, the trip would have been very distressed.

also wi-fi never worked attendant said satellite coverage is spotty over water ..... but we were over land!

Boarding, Seating, Flight Attendants, flight was okay. My seat was uncomfortable.

Paid extra for a “comfy seat” which was anything but!

It was cancelled unexpectedly so we rented a car and drove home.

Everything that was available was excellent. Spacious and comfortable, with lovely and helpful crew (one was having a bit of a sour day, but that happens). We sat on the tarmac for one hour and seven minutes waiting for our gate to clear in SAN, but the pilot kept us informed and, amazingly, was very professional in not ragging on the airport (whose fault it was).

Flight was delayed 8 hours so far. Don’t expect to fly when choosing Spirit Airlines. I will happily pay more to never deal with this company again.

This airline is effective for the price you pay, do not expect anything extra at all. You have to pay extra for seat assignment , carry on luggage, food, you name it ...and even if you pay extra for better seats they do not recline.

Got on quickly and easily. When it turned out the other two seats in my row would be occupied, a nearby flight attendant immediately let me know that I could move one row behind me since it was an empty row, I moved into the window seat where I could relax enough to take a little nap. Can’t ask for much more.

Awful. My flight was three hours late leaving DFW and we just arrived at LAX three hours late and stuck on the runway. I heard the Spirit workers at the desk in DFW say that we were waiting on a crew. I am extremely disappointed in Spirit.

Canceled my first flight for no discernible reason and couldn't rebook me on to a new flight until the next day. They did not compensate me for the delay in any way.

At LAS airport, bag drop process was hard, you need to pay for a faster drop. There was a long line for a free drop and you need to do it by yourself. No one helped you. Bad experience at LAS airport.

Terrible airline. Cancelled the flight less than 24 hours before the flight. Caused me extra expenses!!! This will be the last time me and my family will travel with them
