Good. Quiet. Comfortable. The protests nearly kept me from catching my flight. They waited for me! I made it!

I tried to cancel my flight weeks in advance round trip and told I was not able to. $400 down the drain

wish Airlines would board the plane starting in the back first. Makes more sense and I think it would be faster, NO? Everything else was great!

I went Premium otherwise it would have been a long wait. On board I only asked for a cup of hot water and got lukewarm. Cabin crew have poor to no service. But great flight; it went smooth.

Super easy on both flights. Alaska is my go to airline!

I appreciated the check-in at SEATAC - a knowledgeable person was available. I found it easy to ask questions as I went along. I hadn't been at SEATAC for a year and was not that familiar. Parking was fine at Sacramento

My baggage arrived at the airport on an earlier flight. It would have been nice if I would have gotten a text. I waited until all the luggage had arrived before Ivwent to the baggage counter!

I had to check-in my small carry-on at the gate which was inconvenient. According to the people at the gate at SEATAC, there wasn't anymore room in the overhead bins. I obliged. But, when I got inside the aircraft, there was plenty of room EVERYWHERE! It was either miscommunication or incompetence among the Alaska personnel.

Bad. The fight was late and they gave a ridiculous $12 stipend. Better give something or nothing. $12 is ridiculous.

It was a good flight . It wasn’t a full flight so we had space to move around

Had a broken tray in business class. Crew just shrugged it off.

Everything was great except for the seat. The backrest would not stay in the upright position.

public website still broken for years randomly blocking browsers with privacy options active after loading a page maybe once. check-in on laptop was almost impossible but eventually randomly worked. had to print pass at airport since couldn't get back in to load digital pass on mobile firefox or chrome. red eye flight so smooth onboarding, plenty of room to spread out, easy offboarding. onboard wifi instructions mention vpn can cause problems connecting but fails to also mention private dns. no printed or built in menu list, seems weird to require personal device to point at qr code link for menu which does not even allow direct ordering. people with health condition risk related dietary restrictions trying to avoid for example cholesterol and sugar are left guessing what they can order either way without nutritional info highlights (cranberry juice was minute maid cocktail with as much suger as typical can of soda). tap to pay wasn't working and always seems sketchy to manually enter card info. good movie variety, so limited tv was okay.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Mi primera conexión se retrasó por lo cual perdí mi segunda conexión la cual salió adelantada

Crew was not friendly when I went to request a seat change.

There were choices for the snacks. Good choices and tasty lunch and breakfast as well.

The flight crew was amazing. I’m very tall and they moved me to an exit row unsolicited!!! Amazing service.

Really impressive staff at airport and on plane, especially given how busy it was

So so. Terrible aircraft choice for that leg of the flight.

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

United airline kept delaying our flight back to Phoenix for 8 hours before they cancelled it! If they know that we are not flying out for whatever the reason is, why did they keep lying to us for hours. We could find another flight earlier or even find a hotel with a shuttle. But cancellation at about midnight was not fun. We stayed in the airport all night till the following morning when we bought an Alaska tickets to go back to Phoenix. Total of 14 hours in the airport.

Poor seating comfort, seat cushion too thin, very uncomfortable. My luggage didi not make the flight due to equipment change. At least. United had it delivered the next day. I was without my toilet items for one day.

My experience is based on one crew member. I had found my seat and sat down but there was a gentleman to claimed to the flight attendant I was in his seat. She then came to me and curtly said, "I need your ticket!" No hi, no excuse me may I see your boarding pass? NOTHING! I was taken aback by her attitude and she repeated herself, "your ticket?!?!" I calmly responded with ok, here you go. Only to discover the gentleman was looking at the wrong boarding pass. She gave me back my ticket with no apology. She then was curt with another man who was putting his coat in the overhead bin, already helped by another flight attendant who said it was fine. She realizes it's ok and then asks him if he drinks. The look on the man's face was priceless. She said she was going to comp him drinks. He gets offered a comp drink for a coat as well as an apology, and I got no apology.

Flight cancelled because of the grounded 737s. United was good about it and got us onto a later Alaska Airlines flight to Oakland (not San Francisco as originally intended). Had to go through security again and my wife dropped her MacBook Pro, which broke, a $2,500 whoopsie. But we made it home.

Delays, excuses, delays, and more delays. This company is BROKEN.

Horrible. Delayed on both planes several times. No attempt to fix it

Those seats were way too narrow. I had the middle seat, one person was a very skinny person and we still couldn’t avoid touching each other anytime one of us moved. The other person was larger and we were basically sitting in each others lap the entire flight. There was zero entertainment. The flight was long enough to justify tvs, but no. Gotta sit there in your infant seat and twiddle your thumbs.

Somehow I got “offloaded” even though I had my boarding pass and was in transit Food is horrible Staff were nice and cheerful No headphones were provided on 11 hours flight

Fight crew was not very attentive and the bastions were gross!

Our flight was great we left Kona earlier and got into LAX almost an 1hour earlier as well. LAX AA is in repair so to get out and found our bus to get pick up was a bit confusing.

Plane was good but was delayed. probably not AA fault but caused a 1 hour delay. Seating was cramped.

The staff were very helpful with lots of refreshments on offer. The toilets were clean. The seats were comfortable and entertainment was good. No complaints, it was excellent.

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

I had the exit seat with all the leg room I could ask for. Great!

I wish there were no credit card announcements. I paid hundreds of dollars, I don't need to pay again by sitting through advertisements.

Plane felt so crowded and tightly packed. The chair itself was not comfortable.

I purchased a carry on bag online…was supposed to cost $72 but after a whole slew of bs charges, the total was over $175.00. Because of these hidden charges, I will not even consider flying Frontier ever again. It’s just not worth the hassle. I’m scratching this company off my list forever.

Flight was OK. Seats were good no cell phone charges on the plane no TVs or entertainment.

There were 3 leg for the trip and each leg was delayed by 90 minutes or more. The boarding process takes forever with people waiting on the jetway even though most folks do not have carry-on. The whole process is poorly managed.

Flight cancelled and was told by a rude gate agent that they don’t accommodate on other airlines. Had to wait 5 hours for a connecting flight that had a 7 hour layover. Would not allow bags to be checked early so we couldn’t go through security .Had to rent a car for the afternoon to store bags and get a meal. Also incurred a hotel fee. No apology or reason given for the cancellation- just rudeness.

They cancelled the flight then did nothing to help us rebook. It was awful - I won’t fly with them again

The process of buying the ticket and navigating all the hidden charges that Frontier throws at you was a terrible experience. The actual airport experience and flying was fine.

The truck that was refueling the plane drove away with the hose still connected to the plane and ripped part of the plane off with it

The boarding time. I was in Section 1 the lady in charge just let people in section 3 without see us. Make a line , I have to step out and ask her. We were in the line and she just take my ticket and that’s it, so if I don’t ask her she could leave us at the end! We paid more for that privilege and. She doesn’t care….

See my previous comment which is mostly about our flight from Phoenix to SFO

Terrible. Initially we were shocked by the outrageous baggage fees we needed to pay at check in for our so-called "discounted, economy flight" - we paid over $200 (!!) for one check-in and 2 carry-on bags - this felt like a real bait-and-switch" scam. Our flight from Phoenix to SFO was delayed by 4 hours. Multiple apparent causes (from needing to make space for other planes that were landing late to problem with cabins pressure system, and whatever...). After de-boarding and re-boarding we still waited at least an hour on a cramped, poorly ventilated plane before take-off. Seats were cramped, uncomfortable - did not recline at all. No water until we were flying for a while. No complimentary snacks. Upon arrival at SFO my luggage was sent upstairs to the check-in counter. The customer service person there refused to let me examine a bunch of bags that were sitting on a nearby cart because it was "behind the counter", rather made me wait until another attendant did an exhaustive and failed (?computer) search, came back and told me they were unable to locate my bag. I asked her to look on the cart, lo and behold, there was my bag just a few feet away! Missed my choir rehearsal that evening due to all of the delays. One more thing, a few days later my husband and I tested positive for Covid. Since we both are fully vaccinated, careful about masking and have never had Covid previously, we will never know, but suspect we may have acquired the infection during the prolonged wait on your poorly ventilated plane (person in the row in front of us was coughing). After registering a complaint, we received a measly $50 voucher for future flights. Needless to say we have no intention of flying with Frontier Airlines ever again.
