Had a great flight. Delayed takeoff, but comfortable. Snacks were good.

Pretty seamless, just a tad bit late in taking off and landing.

after landing, we stay 2 hours on the taxi way before reaching the gate The airline and the crew were good though

My flight to Chicago left and landed early. My return flight left two minutes late and arrived 2 minutes late. My seat selections were ideal! There were no snacks going to Chicago and no snacks on the return trip. There are no charging outlets on board.

Gate agents were informative and friendly… flight attendants were as well. Had a fun time chatting about their legacy AirTran experiences as a former fan of the airline that Southwest acquired.

The fluidity of the entire process of boarding the plane the flight attendants attentiveness. The flight attendants also provided coloring books for my kids who loved it.

It good. Just not that plane didn’t have power outlets to charge devices etc.

We stood on the tarmac for over an hour. Very bad turbulence the whole ride. Very to get to the restroom.

Healthier snack would be much appreciated. Love traveling on Southwest!

Left on time and arrived early. Brand new plane and no parts missing. Comfortable seats. The actual Captain spoke prior to the flight and reassured everyone about safety. Crew was so nice and fun. Perfect flight!

Alaska Airlines demonstrated their insensitivity and lack of compassion when I asked for an emergency rescheduling/cancellation due to a dire family emergency. My father was in the Hospital ICU with a terminal prognosis with no other family in the state to help manage the situation and I called AA to ask whether something could be done about moving my flight to a later date, but the AA agent on the phone was firm in not offering any alternative other than to tell me I had to eat the entire cost of the flight. I did not appreciate having to manage that loss on top of juggling time-sensitive matters with my family as my father and I dealt with his life-threatening emergency. I'm very disappointed in the airline for not even attempting to provide assistance other than to quickly shut me down completely. I was really shocked with their treatment of the matter and unlikely to use their airline again.

The flight was canceled and dumped everyone in Albany. I still haven’t received reimbursement for transportation for getting to NYC or appropriate compensation for the cancelled flight.

Alaska airlines agent helped me greatly to reschedule my flight. The flight was also very comfortable and the flight attendants were very friendly.

The final trip home wasn’t as bad as the trip there. Even with the paid upgrade the comfort level was mediocre at best.

Terrible. After boarding we sat on the runway for 1.5 hours "25th in line to take off" ... Alaska Air is on 7th terminal , far away from rest of airport

Better sinage at check-in counter on lines for baggage check in and boarding pass check in, specfically at JFK. It was a mess to figure and wasted a lot of people's time.

Major flight delays, it was a 1.5-hour delay. The gate kept changing about 3 times in Seattle. very hectic and chaotic.

I am shocked at how utterly mediocre the First Class experience was on Alaska Airlines- I really expected better. There was a delay with the food delivery, so we sat on the plane for an extra 30 minutes- not once during that time was I, nor anyone else in First Class offered anything at all, not even water. There's no tv or entertainment available? Really? In modern day? And the Wifi was $8 for the connection that actually works, but free for the connection that didn't work at all? What century is this? While friendly, the staff seemed to be much more concerned with their own personal time while working- listening to headphones, on their phones until someone needed them, I'm so disappointed I can't even believe I was able to find these words.

The plane was delayed for over an hour because of a family who didn't speak English, and didn't understand what was asked of them. While I understand the delay, I thought it was unfair to keep us all waiting for over an hour to get to our destination and a better approach should've been exercised.

It was a very uncomfortable flight. Completely full with an unnecessarily slow boarding process. Zero entertainment on a flight that was longer than 5 hrs. Based of this experience I would not recommend this airline to friends and family.

My flight was canceled, and instead of rebooking me on a non-stop first-class flight for the same day, which I originally had, Delta rebooked me on a one-stop flight for the following day. When I checked the Delta app, I noticed that there were available flights for both the same day and the next day. I believe this indicates poor management on their part.

So terrible. My flight was 4 hours delayed and we weren't notified til last second within an hour of boarding. WE had to sit on the plane for 4 hours. ridiculous.

The CRJ-900 was clean but the overhead air vents were broken in our First Class row, making the cabin very hot until about 30 mins into the flight. The flight attendants were both extremely apologetic and accommodating though so that is why I rated the flight as very good. They checked on us many times and truly showed they cared. The snacks for an hour and a half flight could be better. Would be nice if there was a small plated meal over convenient store snacks. WiFi also was not working. And it would be nice if Delta had adjustable headrests on these planes.

Horrible. Faucet in sink not working, wifi not working. Didn’t bring food or snacks

Gate agent showed up 20 minutes before boarding and was not at all friendly. Had to take this flight due to the one on the day before being cancelled and any later options were already full with long standby lists. Despite having paid for Delta Comfort seats, Delta did not allow me (or anyone) to choose their seat. The agent assigned them for everyone just prior to boarding. Self seat selection was allowed on the original flight. Flight staff was great - very friendly.

Five hour delays every hour, I wish it were all at once

Left /arrived on time. Decent seat space. Like the wifi/plugs and entertainment. Windows and tray table were kinda gross. Attendants didn't start snack service til 40mins before landing. Two rows before us, captain came on to say there's turbulence and recalled staff to seats. So, no drink/snack. Later, attendants didn't stop to see if we had trash nor even look our way. Felt invisible! Almost all pilot announcements were not only unintelligible, but so quiet. We had no idea what she said.

Gate agent was unhelpful for handicapped boarding. Flight attendant seemed untrained.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

The crew was horrible. Cleo was the most unwelcoming flight attendant I’ve ever had.

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Delayed by 2.5hrs any longer and they would’ve had to honour their own policy for breaking their own rules and regs. Not cool, especially when I have an infant child that needs to stay on a routine and they get schedules.

They had three choices for snacks - but you could only have one - and they ran out of the dark chocolate before they made it all the way down the aisle... Packed flight - limited service.

Terrible Initial delay for almost an hour before boarding and departing in Seattle. Then a “customary” wait on the tarmac in Newark after landing for half an hour. I call it customary because it happens almost every time I land in Newark. I do t know if it’s Newark or United airline but it’s a travesty . I use Newark because it’s closer than jfk to where I live but am strongly considering switching because of extremely poor in time performance and Condé and delay after landing

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

Wheelchair assistance was not complete. The person left me at the departure gate without informing the groundstaff of my requirements. I had to walk to the departure counter to ask for help to reach the plane door. The crew informed me that in future they were not allowed to help passengers like me, senior citizen and Wheelchair passenger with placing their carry on bags in the overhead compartments!

Very bumpy flight & the crew was not happy to be there

Uncomfortable! No entertainment and no food Went and arrived on time

boarding announcements werent clear/loud. Tired of those cookies. Of the 3 staff/attendants, 1 was good and the other 2 were mediocre.

Long delays to board due to mechanical issues with plane.

Boarding was awful - no order, people cutting in line, completely chaotic Planes are very old and uncomfortable. Noticeable difference between Delta and United on same route.

This flight moved Gates several times in a short time period, from B to C, which required a substantial walk or rail ride. Then the flight was delayed more than 2 hours and the food was subpar compared to other flights.

Significant delays on my trip to Chicago and my trip back to NY

Terrible steward... Plane was quite empty... I asked to move "back" in the plane and the steward said no... Unnecessary power trip of mediocre people.

It was really a terrific experience both going and returning on AA. Staff and crew were professional.

Flight was fine, but not having WiFi was a major negative

Everything was excellent and I enjoyed myself. Thank for everything

Really good. I accidentally left my duffel on the plane and the reps were so friendly in retrieving it.
