Great no problems. Very friendly. An hour ahead of schedule

Great no problems. Very friendly. An hour ahead of schedule

The reduced size overhead compartments were a surprise. They keep getting smaller and smaller while amenities keep getting fewer.

Great ! The counter staffs in Boston helped me to wrap my broken luggage with a plastic bag to prevent my stuffs falling out.

I arrived at 7:15 for an 8:30am flight. The winds in Burbank were keeping all flights down for the morning. What ensued next was absolute chaos, poor communication and chaos. I had booked a flight last minute because my boyfriends father was dying and o needed to be there immediately. There was absolutely no consideration for communication about what was happening with our flight after there was discovered to be a mechanical error. There was no mention that vouchers had been sent by email For food and I ended up wasting money on my lunch that was horrible. I literally bought the food when I had been emailed about a voucher. . I sat there now at 1:45 and tried to get some answers because the time was ticking. Your lady was so helpful and rushed me to get a flight out of United. I showed up to sfo 6+ hours late and was able to say goodbye to his father. But it was just a horribly communicated day. Please do better

Both of my flights were delayed. This is the 2nd week in a row that Alaska has been delayed. Not a great experience.

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

Pretty bad. Delayed flight that potentially could have caused missed connection. Misplaced luggage, inadequate response.

Great experience with Alaska Airlines. The staff members were, kind, helpful, friendly and professional.

Flight was very dirty. The magazine was a dirty mess. When asked for a replacement it never came. Poor quality flight attendants.

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

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Great experience overall. Check in at Austin was congested as they only have about 6 check in kiosks, one was broken, and there was a lot of Spring Break travelers.

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.

Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.

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

Horrible. Flight ORD to CGH was okay, but Paris was a nightmare. Old planes, delays, involuntary downgrades, broken planes, terrible communication. CGH to CPT was my worst flight ever.

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

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

Was a great smooth flight from Detroit to San Diego.

The boarding process was terrible especially with an indirect flight Chicago to Seattle to San Diego was terrible talking about we overbooked a flight idk if I’d take this airline ever again we got off our flight from Chicago to Seattle and we traveled for business and they told us our connecting flight was over booked and their was no seats asking people to take a delayed next flight and they don’t tell anyone coughing to wear masks seats 30A-B were terrible during the flight no one wants to sit next to people coughing all around I don’t want to be sick traveling for work or get sick anytime it’s very upsetting the staff doesn’t take this stuff serious to tell them to wear masks when they see people coughing and sneezing

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

The control panel for the seat back screen did not work at all after takeoff.

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.

Unfortunately our flight was delayed by 45 minutes due to Kate arriving aircraft. Once we stated everything was great.

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

I contacted both carriers months beforehand to change the cabin (booked in April) but to no avail (united asked to contact Swiss since it was their equipment, Swiss told me to reach out to united). So yeah… My seat was pretty worn down, legroom on 27K was more than enough, but still economy seating so, getting to know your neighbours was easy. According to ground staff, the flight was massively overbooked- and this showed. I ordered a gluten free meal beforehand (which was honoured) but for breakfast got a bread roll and croissant 🤷🏼‍♂️ The connection itself is great. Leaving SFO late PM to arrive at ZRH in the afternoon makes it easier to get re adjusted again. However, and since I’ve flown this connection a couple of times in the past, I will rather deal with one carrier only and include a layover on the east coast.

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.

Excellent- plan was barely populated. I cannot remember a flight where I was able/encouraged to stretch out!

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

Had technical issue which delayed the flight period. Flight crew knew there was 5 passengers that the connecting flight was within 15 minutes once at the gate. Rather than identify the 5 passengers to assure they got first. The flight attended mentioned it but didn't assist to assure passengers with connecting flights off first. This caused a hardship and our party of 3 missed the connecting flight.

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

I don't like that I have to pay if I want extra leg room. The seats are so expensive; I sit in normal seats and my legs and knees cramp the entire flight. I never feel comfortable on AA flights.

Flight was delayed at departure due to weather and the need for de-icing. The flight was smooth but there was a delay at arrival due to weather. We were in a hold for 20 minutes or more. The flight arrived more than 30 minutes late. Airlines have no control over the weather and I'm glad that they follow all safety procedures. Had to wait a long time for my checked luggage. Whole process was slow and the bags arrived wet due to the rain. The onboard wifi and entertainment access was spotty and the signal was dropped several times. Otherwise the crew was great and friendly. They tried to get everyone's bags stowed and seated so we could take off.

If they could pack the seats closer together they would...

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….

Was just ok with over selling I guess. A lot of people in a short space and when we finally arrive i20 minutes, waiting to get out from the plain because we were waiting authorization for out boarding? Something like that.

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

They changed my flight and did not want to accommodate me or try to help me in any way. They do not care about their customers.

The check in at the airport was awful. Told I need to pay for a bag. The item was taken at screening. I went back to get my $ back and they gave me a coupon with a QR code that doesn’t work. Worst costumer service ever!!!!!

4 hour delay because they used our aircraft to fly a different segment (per the captain)

Lost baggage on my connecting flight. 24 hours later, still no update on my bags.

I had to cancel within 1hour of the reservation an they put you through hell to . no live customer service desk. I'm handy caped and they make it almost impossible to cancel. They are steeling my money. You should not have that airline on your site. Contact me and I will give you all info. Of what the are doing to me just notable treatment they are set up like that to take people

absolutely horrific. delayed flights, overbooking. over charging. nightmare service beyond words. stay away.

My husband didn't get boarded on this flight. He was asked to pay $50 extra by the Frontier staff to get two boarding passes for check-in at the Las Vegas airport. He refused to pay this extra $50 charge and tried to do check-in online by himself but it seemed to be late with only 7 mins left. It ended up that my daughter and my husband missed the 7-minute time window. They had to take the next non-direct flight which took more than 12 hours from Las Vegas to San Francisco, a very poor experience for them.
