An hour before flight was enough time for departing from Santa Rosa. (I doubt anyone is at the airport and working at 4:30am).
MariaFlew with Alaska AirlinesSJC-SANSep 2024
Fox car rental was very slow at their desk for getting a car.
JamesFlew with Alaska AirlinesSJC-SANJun 2024
It’s pretty simple there. It’s one of the better airports.TSA has never been a problem for me there it moves and is mostly efficient… I was happy that we didn’t have to takeoff our shoes, which surprised me. They’re always seems to be long walk to the gates coming and going not sure why that is
BradFlew with Alaska AirlinesSFO-SANAug 2024
Alaska airlines with the SkyWest planes have 'no middle seats'. That is a comfy way to go.
Verified travelerFlew with Alaska AirlinesSFO-SANJul 2024
They could smile more! It woukd greatly improve the mood in the packed aircraft
JoonwonFlew with Alaska AirlinesSJC-SANApr 2024
The airplane is a quite small one, compared to the regular size, so pls be ready for some restrictions on carry on bags.
BrianFlew with Alaska AirlinesSFO-SANApr 2024
LAX and Seoul, Korea by far are the best airports
Verified travelerFlew with Alaska AirlinesSTS-SANDec 2023
I would be curious on the flight delays due to rain and fog out of Santa Rosa. It seems they could be above the average

Great experience flying Southwest. The crew was really kind and helpful, and very friendly with our toddler.

Great experience flying Southwest. The crew was really kind and helpful, and very friendly with our toddler.

Plane late from DC to Austin 30 minutes. Crew made up much of the time enroute to San Diego.

Fine, but how to board on SW versus othrr airlines, is just lame. Goood staff though and all was solid otherwise.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a not a great airport.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a hell hole of an airport. It is the new LaGuardia. Everything Cobbled together. Security gates closed. Terri directional signage

I will be flying again Southwest Airlines. Friendly crew, comfortable and affordable.

The plane arrived 25 minutes late, and the Wi-Fi was slower than it usually is.

Forget beverage, they didn't even have water for half the passangers?

Can not wait for seating change to reduce the amount of pre boards - it’s disheartening the abuse. And then then deplaning

The crew was nice. Boarding sucked. Instead of loading from the back to the front people just sat wherever and you had to wait for them to move to get to a seat. And the flight was 25 minutes delayed.

The flight was canceled and very little help given at the check in desk. Everyone at the desk says: just go on the app and see how they rebooked you. I mean come on it’s embarrassing customer service.

The registration was chaotic. The kiosks didn't work for most people, and most had to do registration and receive boarding slips with a person. It took about an hour to get through he process, and I was worrying that I will be late to the flight. However, the personnel was great - courteous, professional, and was able to work through the problems.

I upgraded my seat and the service and boarding were wonderful. My flight attendant was very helpful when I experienced nausea on the flight (a first time experience). Flight arrived early which was nice. The only negative was many airlines have screens to provide some on flight entertainment, this aircraft did not. I had planned to read and listen to an audiobook on my flights, so no big deal on my part. The USB plug ins were broken on both my seat and the center seat, so I was not able to charge my phone during the flight, I will add 2 of the three USBs were broken on ride from San Diego as well. I would attribute this to the design, it is a very awkward angle to plug in, so frequent and perhaps not so gentle attempts to plug in have caused them to break.

Stay with what you are doing. Excellent service and ahead of schedule. Well done.

We had to cancel and we’re treated fairly with 100%refund quickly

There was an issue with water that led to us not having potable water onboard. They dumped the onboard water and we were two hours late taking off.

All good. Great food and entertainment when there isn’t any on a one hour flight

The flight from San Diego to San Jose gate 28A The two persons working there didn’t even turn on the display board. The display board saying to Sacramento. When I asked she was rude and showed the board . Then he realized And changed. Every one was confused because we are running late to catch that flight coming from IAD. Very irresponsible staff.

Great crew, great boarding, old B-list movies, no free meal service, child kicking my seat back all flight long, early arrival, then 40 minute, confused wait for bags.

I liked the flight attendant named Tyler. He was charismatic and genuine. I like the pilot in my second flight, he was considerate to everyone’s feelings. I liked the people I sat beside. I like the plane size. I like Alaska airlines

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.

Awful. Worst airline I have ever been on. Crew were among the rudest people I have ever dealt with. United staff members were rude and disrespectful. My flight was delayed, causing me to miss a connecting flight. I understand things happen, but when staff start lying about what actually happened, that is when I have an issue. Just be honest, really it isn’t that hard. I’m being very honest with this review and I don’t find this difficult what so ever. In fact, because of United Airlines, my Christmas holiday was off to a really rocky start. As someone who has traveled across the world, it has only been United that I have had a truly awful experience.

Boarding always seems a bit chaotic. Seat spacing could leave more for leg room.

Good flight. On time. Boarding and seating was easy. Crew were really friendly, yet professional. Bathroom (by cockpit) was small but serviceable. Some the seats were showing some notable wear & tear, but were comfy. Very happy UA customer. TY! 🤛🏽💗

We arrived early and finally made it to our gate almost an hour after.

We were delayed 3x and because I didn’t purchase my tickets directly from United Airlines I was told I Have to take care of it myself so I called Underpricer and they helped me but before I changed my flights I took the risk of sticking by what my tickets were and was lucky to have gotten on the original all flight with only 15 mins before take off. not sure if I will do this again

Everything good until we waited for jet bridge at SFO. Then pilot gets on speaker & said it won’t reach plane- too short, need to go to different gate. Then 5 min later, adjusted plane/jetbridge & all ok?!?

Spirit is awful. Too expensive for what you get. Stop nickel and diming.

would be great to get basic water, soda at least and stop charging for carry ons

Your crew is a representation of your Standards and Values. The crew from Seattle to LAX, was very disappointing. The crew was more interested in hanging out at the lobby area. Talking, laughing loudly and eating all the snacks. They did not do regular rounds to see if customers needed anything. This was a huge disappointment. I will no longer be flying with your airlines moving forward.

- flight attendants not very friendly. - Paid for WiFi and plane didn’t have it working , never got a refund.

We got to fly on the new airplane. Much better as it’s roomier and cleaner than before. Most Importantly it’s much more comfortable. I still can’t move the seat back but the extra space made up for it. I didn’t taste the food or drinks because they charge for everything so I didn’t bother. I didn’t experience the entertainment because I downloaded my own movies on my phone. The crew was great. The flight itself was smooth . No complaints.

I was comfortable because I upgraded. I would not have been comfortable in economy. It was a short flight so there was limited food service and no inflight entertainment.

I thought since I upgraded my seat I would get some perks. Free water, free snacks. Free carry on luggage.

It’s ridiculous to pay for carry-on luggage. I also wasn’t given an option to specify I have carry on bag at time of ticket purchase. I also could not specify I have carry on luggage at time of online check-in.

Delayed fight LAS to LAX. OK, fog in LA, not your fault. But all your staff, onboard in in lounge, speak so fast, enunciate so poorly and often have a accent that it is impossible to understanding anything they are saying.

The gate area was terrible at San Diego airport -way too crowded in a small space. Since my husband was driving to our destination, we did not have to take any luggage so my kids and I only had backpacks. Therefore everything was easy and smooth. And we didn’t have to pay up charges for everything and it was a short flight. I tried table was broken and it was a little cramped, but it was fine for what we needed. I probably would not fly spirit on a longer flight and if I had to take baggage.

Frontier had yet another flight cancellation. Have never made a complete round trip with this airline without at least one leg getting cancelled. Miserable flights - dirty, uncomfortable planes that apparently always have issues since I've had multiple delays and cancellations with them.

Flight was delayed 3 times, would have been nice to have received text message instead of email notifications. Frontier app wasn’t even updated accordingly, no gate number disclosed. No agent at front desk of gate to inform of delay. Very confused and left if the dark

Everything went as planned. Crew was great. Seats were still not that comfortable.

They changed the timing , first delayed by 4 hours then went back to 40 mins late, we had to run back to airport to not miss our flight. This is ridiculous

No frills for sure. No gate announcements about flight delay, not even water to drink on the flight.

I loked walking out on the tarmac to board and no first class. I didn't like that they have no snacks or onboard wifi to bide your time.

The plane was clean, the crew was friendly and helpful. It’s a low cost airline so there was no food, drinks or in flight entertainment but we didn’t expect any of these things. In the room for improvement department, they should install USB ports in seats to charge mobile devices.

I was surprised that all baggage, including carry on, were charged. Each additional bag went up in cost. Really disappointed in the additional costs.

It was a redeye flight, so every passenger just wanted to sleep, but through the entire flight, the flight crew made announcements over the loudspeaker at maximum volume every few minutes making sleep impossible. For example: it’s 2am, and the crew decides to give an extremely detailed announcement about snacks and beverages for sale. And 3am is the perfect time to wake up everyone with a lengthy announcement about how to get a coffee refill and how to take advantage of new offer from frontier for a credit card.

The takeoff was the smoothest I've ever experienced on any airline and this is the first time I've flown on frontier so this was an extremely pleasant surprise!
