My seat. The reprentative on the phone was bad. The passengers screamed at each other and no one stopped them. The directions boarding the plane were unclear. There was a medical incident and the ICU nurse present said the women was having a cardic incident. Cooler heads determined it was a UTI. I had a allergy attack and a guy got a mask from the flight attendent and told me to wear it. He "had kidney failure". Why didnt they tell him to wear the mask, why was he even on the plane? It was embarrassing, he said hurtful things. By the way, I have a degree in Medical Micrbiology from Northwestern Medical school. MT(ASCP). Look it up. I Know the difference between allergies and an infection. But we had to listen to the unstable screaming man.

The pretzels have no taste. How about a choice of snacks? The flight itself was fine.

Glad they offer free meal, & I got a complimentary drink I’d like coffee,tea, or water offered 3/4 into trip

This was my first time using Alaska. The best thing about Alaska is the people. Everyone that I had any contact with couldn’t have been better. So far on this trip no complaints. I will use Alaska again

Could not check in online. Called airline twice, thinking Hawaiian Airlines could check me in during phone call. NO. In 2nd phone call, Customer Service explained that due to “transition period” of Hawaiian Airlines/Alaska Airlines merger, I could only check in at the airport. In addition, flight to Kahului was late at arrival gate; I made connection to Lihue but my bag did not, so I had to return to Lihue airport a couple hours after my arrival to retrieve the bag.

Full, attentive service from the fist class cabin flight attendant was superb. Really exceeded expectations.

The stewards were too loud and chatty with each other

Definitely one of my favorite airlines! I always have a great experience with Alaska!

My flight got canceled never left san diego and miss out my fam event

Food and entertainment not applicable - standard drinks and cinnamon cookies; crew did not do a song and dance for us so no entertainment. I like the slightly better leg room than American Airlines - at least it felt that way. Flight crew and atmosphere seemed more welcoming than American, too.

The flight used a B767 with a very old interior from before 2014. The entertainment system did not work at all during the flight despite attempts to reset the system. It was like they flew this route just to be competitive.

Crew blocked exits to front of ship with galley carts. Also split five person family apart on international flight without fixing.

They changed planes and the new plane couldn’t carry enough fuel to fly across the country so we had to stop in Kansas City to refuel. Flight was delayed .

Flight was too crowded and seats are too small, especially since passengrs are getting larger. Having a middle seat is ALWAYS tough! Woman on my left was large & kept creeping in to my space. Flight personnel were great! Have more savory rather than sweet snacks please.

Flight was crowded and the woman sitting on my left was large & kept crouching in to my space. You need bigger seats or smaller passengers to fit into the seats you DO have! Snack were OK. Would appreciate if airlines had more savory rather than sweet snacks, thank you!

Delayed flight (1hour) plus a long layover after an overnight flight with no backup plane available.

We were delayed, which I think had to do with air traffic control. Otherwise, everything was great.

The boarding process needs to be refined. Sometimes the gate crew calls out the zones and then flip to showing the.zones boarding on the gate monitor display. So, unless you are huddled around the gate lanes watching the monitor, you could miss your boarding zone. Suggest the zones be announced each time a new zone is allowed to board.

The boarding process needs to be refined. Sometimes the gate crew call out the boarding zone, and then flip to the monitor to show which zones are boarding. So unless everyone is gathered around to see the monitor there is usually confusion as wi which zones are boarding.

On time flight. Seat comfort could be better in the Comfort section.

We Left Calgary 1/2 hour late and that made for a tight connection in Denver. After arriving everything was done to help us make our connection. That was a great effort. Thank You United

The entertainment available didn’t work for anyone on the flight. Long 6 hr flight with no entertainment option and the staff didn’t know until an hour into the flight when we made sure they knew about it. They had no way to fix it.

Late FA meant slow boarding. WiFi did not work. I’m a medium plus sized passenger. The seatbelt was for the first time ever barely fitting. And we delayed on the tarmac 40 min

My husband and I had boarded the flight from Denver to Chicago, and one of the last passengers to get on the plane opened the overhead bin above my husband's seat and threw his bag out of the bin to make space for his own. He said, "Mine is bigger!" The flight attendant supported the new passenger. They didn't care that my husband has two artificial knees and must have the foot room in front of his seat to be able to fit his legs in -- and to be able to stand, much less walk, at the end of the flight. I have never seen this happen before, and it was a disaster.

I understand stuff happens, but plane failures are likely due to lack of maintenance. Additionally, air conditioning wasn't working, no snack/drink service, no WiFi. Fortunately, the crew was communicative and light-hearted. United grabbed another plane and we were able to get to our destination.

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

Excellent flight. Boarding was efficient and departure was on time. Smooth flight with on time arrival. Deplaning was also efficient.

Our flight was understandably diverted to a small regional airport in Laramie, Wyoming due to weather conditions, which I fully recognize and appreciate. However, the low rating stems from the experience that followed: passengers remained on board for over an hour without the option to deplane and stretch, despite the aircraft being stationary. Although the pilot opened the cabin door, only he was permitted to exit. Meanwhile, passengers grew increasingly uncomfortable as warm summer air entered the cabin through the open door, and being in the second row meant we were impacted immediately. While the flight attendants made efforts to keep everyone at ease, I believe allowing passengers to deplane briefly, given the extended delay, would have significantly improved the overall experience.

I never flew. Flight was canceled. DIA worst airport in the country. Avoid at all costs.

Very rough getting into denver. my kid threw up it was so rough.

Do not fly on WestJet if you have a connection. It failed to integrate with my connecting Delta flight and I almost missed it.

There was a man who was very rude at boarding. On the other hand personal bag measuring box is too small compared to USA airlines,

A little better seat cushions would be appreciated. Crews were all good.

The process and flight were both smooth and trouble free

Flight delayed 3 hours, missed my connection in Atlanta. Instead of getting to Savannah at 6PM arrived after 10:00PM Middle seat, couldn't get isle or window, couldn't book my seats in advance, had to book at the gate. That's a 1st for me and I used to travel a lot

my carry-on bag was delayed and I did not receive it until the day of my return at the airport. This delay caused me significant inconvenience, as I did not have access to my personal belongings for the duration of my trip. I had expected to rely on my carry-on items, and being without them negatively impacted my travel experience.

Technology issues at the bag-check counter caused a delay, and we were unable to check out our bags, ultimately missing our flight. They offered no assistance other than telling us to book another flight out of Calgary. We arrived with plenty of time; if there hadn't been an issue with the kiosk and the length of the lines due to the technical issues, we could have made it home.

Worst check in and bag drop off experience. Staff were incredibly rude given that it’s the WestJet system that is faulty.

The staff at the airport and on the plane were wonderful I especially wanna acknowledge the staff who boarded us at the Calgary airport. The women who helped us board at the airport were incredible… they were so kind and sweet…I very happy with WestJet and I am hoping I can fly more often to Canada.

We were happy with our experience. The price for tickets was much less than Delta and we actually took off and landed a little ahead of scheduled times.

Extremely turbulent landing. Crew was friendly and plane comfortable. Airport and US pre clearance was understaffed

The airplane is way too tight, you can hardly enter into your row to sit.. more like kids seats than adults.

taking our carryon and forcing us to check it through

Wifi was great. Kind air crew and comfortable seating. Also liked the entertainment options.

Great flight. Only complaint is it took over an hour for my luggage to get to the carousel on the return to LAX That was irritating

I knew I was going to fall asleep unsettlingly from exhaustion so I warned the guy next to me in advance. The attendant took to checking on me frequently and even insisted I take my snack because I said no while sleep hazed and then absolutely wanted it about 5 minutes later. He was So caring and kind to my situation!!

First message when all on board was that we didnt have a pilot, then they found one, then it was something about the bridge something not working, they will either fix or do manually. Flight of course was leaving late with all the cruise guests worrying about making it to their ship in time. Then only some luggage made it off the ship. Around 15 to 20 people waiting. 45 min later arrived except mine. I asked the rep at the luggage conveyor, he asked me my name. Then said it was not picked up with the first batch so they put it in a room. I was going to take public transport but now worried about time so took a taxi that cost me $65 USD

The flight was very smooth and good. Boarding was fast, but the staff was just decently friendly.

Air Canada flight staff are in contact negotiations and they are less than happy and it show. The process of self checking baggage is less than desirable with lack of support staff to help

A sandwich and a drink would have been better thank a snack bar...
