Alaska did a great job of accommodating my needs and treating me fairly. I appreciate their willingness to smile and be caring.

Alaska did a great job of accommodating my needs and treating me fairly. I appreciate their willingness to smile and be caring.

They did not do a snack and beverage service for the main cabin, but served the first class cabin which we could all see. Trying to understand why we didn't receive service. Disappointing. Also one of the crew members was not friendly.

I have been trying to cancel my flight from 2 hours before and still have not been able to

We showed up to our gate less than 15 minutes after boarding started and they wouldn’t let us in. It was still 15 minutes even before take off so we’re weren’t even late to the flight.

The flight itself was great. But we had to wait over an hour to deplane so I missed my train. Not the crews fault. They were wonderful!

Wish there were more complimentary drinks available - only had water and apple juice. Also - no snacks were provided during the flight, but we were offered some items as we exited the plane.

On this flight there wer only 25 people on board. So no one in 5 rows ahead of me and noone in 7 rows behind me. So very chill.

Departing flight for our weekend trip was cancelled due to weather which meant our return flight was useless. The whole thing was difficult to get support through but Alaska did recover and was able to reimburse us for the flights yesterday. For some reason, Kayak was not kept in the loop, adding to the confusion.

You sent me an email saying boarding was at 9:29 and AA sent one that was 8:29 on Sunday morning. I had to call AA to get that it was indeed 8:29.

The airport crew and on board experience was fine. The problem with Alaska air is that there is zero customer service over the phone when you’re trying to buy your ticket or change anything.

Despite paying for an ‘upgraded’ seat in row 1, I had to put my luggage in the middle of the plane. Snacks were bleh and seat was small and uncomfortable and I am not large. Attendants were fine but not super helpful. Plane just seemed outdated.

Delayed for no reason at all originally. Then they said it was due to weather conditions. Communication between kayak and Southwest was terrible because both displayed different delays and departure times for HOURS throughout the day. The plane then had technical issues which delayed us from taking off even longer. Didn’t actually take off until 11:45pm when the original departure time was 7:35pm. I didn’t get home until 1:30am the next day. I was exhausted and pissed off. I am not confident if I’ll fly southwest in the future or use kayak to book.

Flight was fine. Only thing was flight was delayed nearly 2 hours. Flight was originally scheduled to depart at 7:50pm but didn't depart until 9:50pm. I got home around midnight. It was later than desired and I had to get up early next day to take kids to practice. I have noticed that last flight of day on West Coast for Southwest always tend to have delays.

Terrible delay today. also, waited 90 minutes for baggage to unload in Seattle earlier in the week.

Seated at front bulkhead for a smidge extra leg room away from home and on flight back home. Away crew was very proactive about assuring our carryons had space close behind us (because no seat in front of us our personal items had to be in a small bin overhead). They actively required passengers place overhead luggage on its side so more items could fit in bins. Home crew made no such efforts. I had to struggle back rows to get overhead bags upon landing, no crew help then either, and some disgruntled passengers as I and others retrieved our bags. There was a system that worked pretty well. The home bound crew just didn't feel like working.

Flight left on time and was early landing. Seats not comfortable and not enough space…

It would have been better if the flight was on time

No wifi, seems to be very common with Southwest currently. Everything else was normal.

Poor customer service, no accommodation for passengers when the flight was delayed over 5 hours.

The flight was late. The crew was rude. There was no food. Cramped and uncomfortable. Nothing about this flight was good.

I'm 6' 2" and even in economy plenty of leg room

great! appreciated the last minute upgrade to Comfort+ exit row, as well

My seat was changed without my consent. It wasn’t a major deal but annoying.

The Airline Attendant found us in flight and moved us to seats in the front of economy due to the short time we would have to make our connecting flight. We really appreciated it.

DL486 could not get to the gate due to jet bridge malfunction. We moved gates. The connecting flight of LAX to MCO was not communicated with. Even though we were in the same terminal, DL482 left without about 10 of us, including a mother and her 3 children. I got to the gate at 7:34 am which is past the 7:20 am last call for a 7:35 am departure. Had they waited 5 minutes, all of us would have made it on board.

Delta has joint the nickel and diming airlines. The experience is getting worst by the day. 1,000,000 miles for a trip to Asia in Business Class where I got the same thing for just under 90,000 miles through an Asian airline. Where is Richard Anderson? Please come back!

Very bad multiple confusion and miscommunication which i ended up missing my flight.

The experience was bad. Flight was delayed to handle maintenance (understandable) but still there was some dew forming and dropping as droplets on few seats. Internet at best was allowing some browsing but at a snail pace.

Both of my flights to and from JFK experienced significant delays. Most notably, my first flight was delayed by six hours due to crew members being affected by delays on a previous flight. While I understand that disruptions can occur, Delta’s staffing and operational planning should include sufficient contingency measures to handle situations like this rather than placing the full burden of those delays on customers. Additionally, the $12 meal voucher offered as compensation was inadequate, particularly given the high cost of food and beverages at the airport. Considering the length of the delay and the substantial inconvenience caused, I believe more meaningful compensation would have been appropriate.

Comfortable seats. Nice service online. Short flight, so not a lot of time to enjoy.

The guy sitting in front of me kept pushing hard his sit against my legs… very uncomfortable

Food was horrid. In my opinion inedible. They did offer some sorbet and one small dish of fruit. Stewards were super stingy with water, coffee, etc.

On-time, direct flight is great. Having one bathroom out of order was unfortunate.

I am absolutely furious with American. they shut the door in my face when I was trying to board the flight and kicked me off of it. They made no attempt to call my name or contact me or anything. They just said they gave my seat away. The customer service response has been atrocious. I will never fly this airline again as long as I live.

The WiFi was out gr entire flight. Had to Diane for almost 1 hour to wait for a gate to open up for plane to dock. Very bad experience.

Not too much it was pretty good all the way around

American Airlines put the food on the wrong plane which had already taken off by the time we took off so we had no food on the plane.

I believe my father had a good flight. What was not good, was the associate who helped us during Step 2 of check-in. After getting his boarding passes and bag tags, we proceeded to Step 2 where we were met with Carol. This was around 3:15-20pm at Phoenix Sky Harbor. She weighed my father’s checked bag which was 2lbs over, she recommended removing a pair of jeans to correct this. My father asked/joked if “she could just let him go” and she fairly rudely responded something along the lines of, “I don’t own the airline so no I can’t do that”. From this point on I just want to assume she was having a bad day. I spent my life raised in a business and front-facing customer service so I understand previous clients can make you feel irritated. How she continued to act leads me to believe she was really careless about her job or racially biased/straight-up racist. After we moved the 2lbs to his other bag, she told us she believed he would need to claim his bag at his connecting flight in Hong Kong, before it could go to his final destination, Malaysia. This thoroughly confused us as we are fairly frequent international travelers and 95% of the time the bag is sent to its final destination without this requirement. Last time we traveled to Malaysia was less than a month ago, so again we’re fairly confused. Multiple times she used a fairly aggressive tone of “I know what YOU THINK, this is what I believe”. The multiple “YOU THINK” as if we didn’t understand what she was saying was rude and insulting, and her tone came along with a insincere smile, hence the feeling of she was racially biased. Despite the fact that she might have been having a bad day previously, it is AA’s airline’s duty to train their employee about international bag protocol, as clearly AA is a major partner of internationally traveling airlines. Carol made the experience overall unenjoyable sending my father off and made us both question AA’s training of their employees.

Old dirty plane but great lie flat seats in business class

No food. I paid over $1.000 for my ticket for nuts and espresso beans.
