An hour before flight was enough time for departing from Santa Rosa. (I doubt anyone is at the airport and working at 4:30am).

Fox car rental was very slow at their desk for getting a car.

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.

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

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

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

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.

I boarded last because of my boarding assignment and was given a middle seat at the back of the plane. I’m 6”1” so it was really tight. I wish I just had a seat assignment instead of a general boarding group. My bag was way at the front and my seat at the back. Was never offered a beverage and had no room to move.

The open seating makes passengers boarding ahead of you think they also have the right to the empty middle seat. Trumper next to me refused to move her laptop bag from my leg area. I did not make a fuss since it was a short flight.

It was a little chilly on the ride. The entertainment was the book I brought, and it was excellent.

orgiginal scheduled flight ( 2.5 hours connection) was cancelled, was given option to rebook between a 1-hour connection or a next day flight. Missed connection flight, and decided to book last minute with an other airline.

The flight was excellent with the exception of being sent from Florida to Seattle before finally being sent from Seattle to Hawaii.

Upon arrival we had to wait for a gate, then when we arrived at the gate there was no one to move the gangway to the plane. Very poor coordination .

Paid additional for seat upgrade, but got same seat as no upgrade.

The first flight attendant who served refreshments was not pleasant at all. No eye contact, no smile, I used my “please “ and “thank you “ and all but had pretzels thrown at me. Next one far surpassed pleasantries and more like Alaska Air! Good leg room, comfortable seats. Boarding was without flaws. I didn’t order food….

I never received a full itinerary of my round trip. I only received the outgoing flight on Sun Country to Baltimore. Throughout my stay in the Baltimore area I kept checking for the information on my return trip to Portland, I didn't receive it in timely manner, so I booked another flight. I received the return flight information on the Alaska flight booked via your sight upon returning to my home in Oregon. The cost of my ticket on Price line was $247.27. The flight was Alaska Airline Flight 9. The confirmation number is YWHLPB. Please be advised I purchased Insurance for this flight. The reference number is UVCV4-X4TK9-INS. I respectfully request a refund for the bookings on, AS 507 and AS 1121.The confirmation number is 72058793562147. Thank you for assistance in correcting this matter.

the departure time was changed several times. At the end we were late 2 hours and 15 min. It was a poor experience

I didn’t purchase any food on the flight or use the entertainment system, so am unable to comment on them

Delay of 4 hours, i understand there was a medical emergency, but the fact that they arrived without the medical equipment and didnt have a replacement on the airport was annoying because they told us supposedly their manager went for one replacement to JFK airport and cross the city on traffic i mean seems so unprofessional! Anyways at least the flight was safe!

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?!?

Was a pain having to leave the plane and reboard but glad the plane was fixed

We had to wait almost an hour for the wheelchair porter to be ready to pick up my mother. And when she arrived in Newark airport the porter was not there and she started walking with her cane and her poor mobility. When the Newark porter found her they didn't want to transfer her bags to the wheelchair for her.

Great onboard crew. Boarding was a zoo, I got in line before pre boarding in Group 2, still had my bag force checked. WiFi was glitchy all flight. Seat and bathroom are both tiny unless you pay $$$ for first class.

Cabin was pitch black, even during meal service. The reading lights for seat 2E/F did not work, and seat 2E did not recline.

- 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.

Boarding procedure is horribly slow. You charge me to check a bag and would not let me carry it on. Charged me to simply select a seat. Charged me for water. Charged me for every little thing on top of paying for an expensive ticket. Your seats are terrible. So uncomfortable, they don’t recline. No WiFi, no way to charge my phone. No entertainment. I mean you Offer noting and you charge for everything. Why would anyone want to fly with you again?

The staff from LAX to New Orleans were rude but the staff from New Orleans to LAX were nice!

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

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!

A lady asked to stop the flight after the tunnel pulled away and we began to depart a flight that was already hours late. The attendance respectfully stopped the the plane and had the tunnel return. After the tunnel returned the passenger claimed to have changed her mind . The tunnel was then put in reverse and the passenger remained on the plane .. They should have sent the sick passenger off the plane like initially replaced. They existed a couple off the plane prior to that situation.. So.. all and all.. it was a long and flight.. .

With frontier you get what you pay for. The flight was two hours late. It’s a tight fit for the number of people they bring but you get to where you’re going cheap. Sometimes that’s more important than a nifty drink and cool TV..

Charges unexpected. For seat that didnt recline. Please reverse extra seat and carryon charge. Bad business that is a bait and switch.

We had an awful experience getting our bags checked in. Frontier’s check in on the app manipulated us into buying the business package because that was the only option available for a checked bag which included two checked bags per person which we did not need. Upon arriving to the airport, we stood in line for what seemed like forever at the baggage check in and there was no one available at the counter. We were first in line and we were afraid we were going to miss our flight due to the baggage attendant being late. After realizing there were a lot of other people waiting at the baggage check in and no one available. I reached out to Frontier and could not get any customer service so I had to call the airport to page the baggage attendant to send someone to the counter to check in our bags before we were able to go through security , I finally spoke to the attendant at the counter and explained to her that we had to pay for two checked bags person a total of six bags when we only had a total of three bags between three people she said to reach out to Frontier and they would issue a refund for the three bags that we paid for and did not need. I reached out to Frontier which I was not able to reach anybody by phone so I had to go through their automated chat feature, which sent me around in circles until I finally reached a representative to assist me. I explained to them what happened and they explained that they were not able to assist me. I continued to push the issue with them as this was very frustrating and they finally put in a customer service ticket where we were issued a flight credit and we were so disappointed because after this experience, we NEVER want to fly Frontier again, and we do not want a credit that we will not use. Frontier charged us almost $500 for us to check three bags which is absolutely absurd! The customer service agents were not able to offer anything else other than a flight credit and I do not feel like my frustrations were truly heard , we will never use Frontier Airlines again ! Truly Theft by Manipulation! They should be ashamed!

I couldn’t check in because the app didn’t work. It took 3 Frontier employees at the counter to get me checked in. Flight left 3 hours after departure time
