I have taken 4 Alaska flights in the past 3 weeks and every single flight was delayed. They give you a $12 voucher for airport food, sometimes too late, after you’ve already eaten. That might get you a bagel. Reservations, rentals, etc have to be cancelled with no repercussions. Will be avoiding Alaska if possible.

I have taken 4 Alaska flights in the past 3 weeks and every single flight was delayed. They give you a $12 voucher for airport food, sometimes too late, after you’ve already eaten.

Window seat and a packed plane. A very uncomfortable flight.

My flights went about as good as they could be. I’ll always take Alaska when possible.

Excellent flight, hour and half flight so no food was served other than pretzels, which was fine. Excellent , very professional.

I made a mistake with my reservation and customer service refused to help me. They basically said that it was my fault and that I need to pay for another flight if I want to make changes. The flight was delayed. I should have checked before I rushed to the airport, but it would have been nice to get an email. At the airport, the waiting area was too small, so there wasn’t enough space to sit. During the flight, there wasn’t enough air and there was a terrible odor on the plane.

I wish it hadn't been delayed. I'm thankful my husband got home safely but I understand turbulence was NOT GOOD.

The flight duration is 1.5 hours. Besides the point of 2h late…

SFO gate staff super fun playing music and singing having customers waiting to be boarded to participate. Flight staff was nice enough. At least not rude like others I have experienced.

I was delayed for three hours. I didn’t really like anything.

Quick boarding No carry on fee Free beverage Reasonable price

Terrible. Delta delays caused us to miss our flight and they did nothing to fix it.

The A330-200 was showing its age but otherwise this was a pleasant flight with friendly crew. The meals/snack provided were pretty good.

The most unprofessional and disorganized experience I’ve ever had with an airlines. After the flight was diverted on the runway and we returned to the gate, there was no communication about the plans and it took an additional 5 hours to get set up with a hotel and a new flight, information that was not readily given to the passengers and mostly gotten second hand from what other passengers heard from each other. Based on this experience I cannot recommend flying delta again

You need to be a hacker to get the (Free) WiFi

I was traveling with my 85 years old grandma and 60 years old mother. Which I requested to get a wheelchair. I went to the Delta Kiosk and asked for a wheelchair.  They brought a wheelchair and 2 minutes (without exaggerating, time is important for me as I am well disciplined with a military background) later they said that the wheelchair belongs to American Airlines, so we need to switch it.  We were like where is the other one so my grandma can use it? They are like, "it's on its way, she has to wait for the other one" I asked them why does she have to wait? Is it ok for her to sit on this one when the other one arrives. Answer was "NO". I guess lack of common sense was the issue. I started to explain to the agent that she can not stand still or wait. Finally, someone said that in spanish "she can not stand, let's wait for the other one" . Delta's wheelchair came, without an attendant or helper. They brought that wheelchair and left it in the middle of the airport. Nobody seemed to care. I had to push her to the gate. Then they finally realized that "wait a minute, there is something wrong with that". So they send someone, who later started harassing us, to tell us how he works for cash tips. Then a "Private Security Interviewer" approached us. I think his name was Carlos (His descriptions - tall for an average worker, ginger curly hair, wears glasses, overweight). He did not represent himself. All he did was show his badge for two seconds and when (later on) I asked him what his name was, he said "I already told you at the beginning". At that point we were waiting to be called at the Delta Kiosk (this is prior to the Customs first check in point). So, Delta Airlines hired "Private security interviewers" to make sure that nobody brings anything illegally to the US. Which is great, makes me feel safe and secure. But, it does not serve the purpose. Let me explain to you why. These interviewers do not know what they are doing or saying and you can clearly see that. They think that they are CBP or Immigration officers. They will get angry If you ask them any questions. Then they will put all these stickers on the back of your passport like they caught "Pablo Escobar". At one point I was sarcastic and told the interviewer that "I like those stickers, It's my hobby and I am collecting them. Can I have more of those?"  and interviewers eyes and brain goes like "error 404". He did not know how to react or respond to that. Then he flags my itinerary on his iPad. Trying to give me a hard time since I asked him about his name, so I can call him by his name. But of course that did not change the fact that his lack of english made everything even harder. After 45 mins of wait and clearing the "Private Security Interviewer" you would think that we are going to be all set to depart. I was wrong. We waited in line to go through the security line, just like other citizens. No wheelchair, disability, seniority etc were important for her. They treat us like she is in her twenties.  On several occasions they forced her to stand up. She was like "I swear to God that I can not walk, my son I wish I could walk, but I can not". They did not seem like they cared. Then finally they realized that she is legit disabled. They let her pass on a wheelchair. At the gate, Carlos showed up to make sure that I am going through the secondary check. They pulled me to the secondary check. And started asking me about my luggage. My response was "I only have one carry-on bag, to make everyone's (including my life) life easier". They asked the same question over again "Sir, do you just have only one bag?" I replied saying "Yes". She did not believe me and said "Just only one". So, I thought she did not believe me and I said "Yes, Si, Si, solo uno". She looked at me and then turned to the agent (Carlos) and stared at him like "did you not ask him about his bags, did you not know that he only had one carry on?". I am sorry to say that but they just looked like a bunch of idiots who do not know what they are doing. Finally they released me after a minute of secondary check. Meanwhile everyone is boarding and my grandma is waiting on her wheelchair. Then we approached the gate agent and I asked her if I could sit next to my family, if they had any seats available. She replied that "I can not change any seat at the gate, I do not have any authority". I replied "I understood". We got on the plane last and I asked our flight attendant if I could change my seat to be next to my family. FYI, their seats were 10 B and C, mine was the 35 D. Meanwhile there were empty seats on 10 D and F. Even flight attendants surprisingly said that "why did she put you all the way back, while we had 1/2 full flight. I will go and ask her". Our flight attendant was great and he made sure that I am next to my family. He went above and beyond and he gave the closest seat to the. Flight was good. Delta Airlines failed to bring the wheelchair when we arrived. Excuse was "Gate changed, that is why". I walked outside and grabbed an empty wheelchair. I put my grandma and brought her to the Customs. Then a Delta Airline worker approaches me and says that you can not move this wheelchair, it belongs to the gate. We will bring you a new one. A CBP officer heard our conversation and jumped in and said, "wait a minute you want her (pointed my grandma) to wait here while you bring her wheelchair?". He (delta worker) responded "yes sir". But when he talks to me, no sir, nothing. The CBP officer goes "Nope, she is not waiting here and I will make sure to pull her wheelchair". If that officer was not there we probably would have had to wait and be forced to change the wheelchair. The CBP officer, again the CBP officer, not the Delta employee, pushed our wheelchairs to the gate. Sincerely,

The boarding agents appeared to do the minimum customer service. They did not appear to try to find solutions to problems.

Do not get fooled by the term “Delta One” flat bed! The seats were super narrow. The ottoman for the feet was so narrow that when you recline the seat in flat bed position, you can only fit one foot in the 8” width space. There was only 1 flight attendant for First Class. The breakfast took 2 hours to get served. Instead of offering French Toast, the served bread pudding. The champagne with orange juice or Mimosa tasted terrible. Almost all the movies offered were ridiculously old. For a long flight from San Francisco to NY, it was frustrating! I DO NOT RECOMMEND this flight!!!

The only real hiccups in the flight were things beyond Delta’s control - turbulence which delayed food service and a departure delay caused by some VIP plane which stopped all departures and landings for 30 minutes - and was never explained to us by the crew. Otherwise good flight. I would fly Delta again.

Checkin was easy, boarding was organized, employees friendly and nice. Was a lovely flight.

I understand why there was a 40 minute delay, but we should have been offered snacks during that time. We weren’t offered it until later.

I loved the wifi, much better than Delta. Seats were old. and bathrooms dingy.

There was no wheelchair or wheelchair escort at the gate..unacceptable

Delayed 4 hours because of maintenance issue they knew about all day. Get another plane. Time is precious!

I liked that boarding and take off were timely despite a 15 minute delay due to weather. The pilot communicated with us the entire flight keeping us informed re: turbulance and slight delays on the runway after we landed.

Has been always great except flight cancelation in the past at very last minute waiting till 2am and we when have to beg for overnight accommodation

There were weather issues and coding problems whatever those refer to, but JetBlue, for two days in a row was unbelievably late. Several hours late, resulting in almost no sleep for passengers like me.

The plane was very hot. There were delays . Generally, the flight was great.

If jet blue is going to offer tv at every seat, fix the headphone connection so you can hear. Haven’t had a usable headphone jack in years

Plane is old and seats are worn. Add to it the plane was dirty. No plugs for laptop.

Always like Jet Blue! It seems, however, that people are getting bigger & seats are getting smaller! We had a very full flight and I couldn't get an aisle seat like I always do. I wish there were more leg room. People sitting next to me were very nice though so it was fine to disturb them if I needed to use the restroom. Otherwise the flight was fine but a bit long.

Airline did not explain reasons why flight was delayed two hours. Explanations were badly needed and rarely provided. Problem seemed to clearly be the airline’s fault and not the fault of the weather or airport.

Very uncomfortable seats and seat backs, and I am only 5’9”. Delayed due to crew issues, spent a long time with no ventilation. Teeny overhead bins. Wifi worked well. Arrived safely.

I was delighted that we were able to get on the 4:40 pm flight rather than our original booking at 6:55 pm!! Other than that, the flight was comfortable and landed early😊

Our flight was delayed many times throughout the day. The final delay was about 8 hours. I spent time in line to speak to someone at their understaffed desk, and also spent time waiting online and then chatting with a service rep. None of the United employees were any help at all. I desperately wanted to go get rest and possibly re-book my trip but I was denied any compensation or voucher for a hotel. I was repeatedly told it was not United's fault and therefore they had no compensation to offer. Overall, a cold and callous experience.

Paid WiFi was only available for a few minutes. Avoid at all costs.

Everything was great, only problem was that flights were delayed

Flight crew and pilots did great. Flight way delayed due to a part needing replacement. Based on what the pilot indicated- the maintenance crew could’ve resolved this more efficiently than replacing whole part- and taken less time

Flight canceled due to weather. Rescheduled flight canceled due to maintenance. I’m stuck!

Pretty turbulent, but not anyone’s fault. They got us there. Impressed that they carried on with a drink service.

Please please take consideration when setting cabin temperature. The vents were not functional and it was over 70 degrees in the cabin during the winter months when most people are used to much cooler indoor temperatures. I was down to my white t-shirt and the sweat pants I wore from Auckland to San Francisco and was sweating profusely and there was NO VENT!

This plane is my favorite despite the very limited overhead space. Seats are comfortable!

The flight landed at LAX we were then bussed to collect our bags. That process took nearly as long as the flight. Luckily we weren't in a hurry!

3.5 hour delay!!! No plane for hours, mechanical issues and poor communication from airline. Horrible! Supposed to land at 8:54, landed at 12:32!

Had the best flight in a long time. The captain was amazing, friendly, kept us informed of any weather or sites to see. Took good care of the flight attendants and made us feel safe and confident. Smooth lovely flight.

The entire airline industry seems to be a total disaster these days, and this flight was no different. They never posted the gate until boarding time, then bused us to the plane, a 777! We then sat on the plane for over two hours, with almost no information as to why. When they did give us information, it was an obvious lie, like saying we would be underway in 10 minutes, while being number 5 in line for deicing. I worked in the airline industry for 20 years, it takes longer than that for each plane, and a pilot would certainly know that. All in all, a 6 1/2 hour flight was 9 1/2 hours on the plane, just ridiculous! The entire time we were given little to no information as to why things weren't happening as they should. And to top it off, the pilot had the nerve to joke upon arrival into Boston that he was glad we had joined them for the short flight from London. Just what you want after 9 1/2 hours on a rock-hard seat, someone minimizing the agony you've been feeling for hours! Oh yeah, and the added time was just enough to allow the snow to start flying in Boston, which lead to multiple accidents, which made our 1 1/2-hour drive home, 3 hours, icing on the cake!

There was no entertainment (the wifi was not working) and no food service - just cookies or pretzels. When we arrived in Boston the bridge to our plane was not working and it took some time to be able to deplane. When we got to Boston our bags were not there and the person who put in our claim for lost baggage said we would have our bags delivered in 24 hours and 72 hours later we still do not have them and no one from AA has contacted us with an update!

Red eye from LAX. The most uncomfortable First Class seats I have ever experienced. No blankets or pillows. One bag of chip-like objects and two beverages for the entire flight. It felt very stingy.

This flight was intense. It was overcrowded, people weren’t following Covid guidelines. And in general, was a mess due to young kids causing a lot of noise and disturbance. I ended up with a headache the entire flight because of it.

Pros: "Check-in started a bit late due to late arriving incoming flight but the crew at the gate as well as in the plane did their best to speed the process. Flight was smooth, lande ontime despite taking off nearly 20 minutes late. Captain kept us informed when, through no fault of American Airlines there was a delay at the gate. Overall well done in these trying times."
Cons: "It will be nice when things are back to normal and actual food is served on flights of 4 or more hours duration."
Cons: "The fact the my connecting flight was delayed 3 hours making us miss the last leg of the flight to Bahrain. I'll never use kayak ever again"
