Everything was fine -- on time, clear, clean. I don't want to pay extra for in-flight wi-fi

First time flying with Alaska and the staff were All professional from checkin to departure! I do plan to book more flights with Alaska. Thanks

The flight was delayed because the pilots had not arrived on their previous flight yet. The flight was 100% full so it was pretty crowded. I miss having the screens on the back of the seats. It would be great if the Alaska planes had the clip so you can put your phone or tablet on the back of the seat in front of you to not strain your neck. Everything else was very smooth.

Boarded the plain and had to wait 1 hour for crew Captain to arrive from another flight

It was fine since it ensure we went to our destination in time.

Overall good flight, smooth and on time and comfortable. Disappointing that food is not served and you can't purchase the snack packs on the plane.

The space for legs in coach is better than other Airlines you can even cross your legs!!

There was a row with three women who were very loud - talking and laughing. In an open, outdoor setting that's fine. On an airplane, no. The flight attendants told the women they were the fun row. It took the woman sitting in the row ahead of the loud women to tell them they were too loud, but everyone in the general vicinity was irritated. I didn't think it would be possible to be so rowdy for so long. Then when we landed we weren't let off at a gate. We had to be bussed in and the bus contended with airline traffic. After dealing with the loud passengers, this was not what I was expecting. An incredibly disappointing experience with an airline that I have always regarded as one of the better ones.

I bought the cheapest ticket. No meal, no checked luggage so I didn't expect much and was surprised by how good the flight and service was. Alaska is now my favorite airline.

Comfortable seat, plenty of leg room which is so rare, overhead bin comfortably accommodated my carry-on bag. Deli box was tasty, service was good, bathrooms were clean. Uneventful flight, which I appreciate. Departed on time and landed early.

Very frustrated with boarding gate crew. She announced the plane was small and they would be limiting us to one item to carry on. Not a problem for me as I understand the tiny planes have limited space!! Not the case here! It was a rather large plane and had plenty of room for bags! So because I don’t want to be one of “those people” who ignores the request to check a carry on I did so asking if I would be able to pick it up at the bottom of the ramp on arrival in Knoxville to which she responded “yes”! Then I watched as every other passenger held onto their 2 items and boarded!! Then when we arrived in Knoxville our 2 carry ons had been put with all the other luggage and we had to go to baggage pick up and wait for all the big checked bags to come off the carousel! So she lied!! Frustrating. Next time I won’t be so nice!

It was a good experience except when boarding a female flight attendant did not go out of her way to assist my teenage daughters in finding space for their carry-ons after their compartments were full.

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

The pilots were good. Disappointing when planes don't have electrical ports

I liked the piloting of the aircraft. Very disappointed about lack of electrical ports. Also, although a short flight. there was enough time to hand out snacks to comfort + seats as was done for first class.

I had a wonderful experience flying with delta. The gentleman taking care of us on our flight was so nice, accommodating, and attentive. He always was smiling and giving pins to the kids which made me smile. The flight was quick too and without turbulence. Thank you for the great flying experience.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

All flights were on time and boarding was issue free

Terrible! The plane was old and you are required to connect your own device to their Wi-Fi rather than have entertainment options in the back of the seat in front of you. The Wi-Fi went out during the flight and there was only one plug for the devices every two seats. Three out of five surrounding my family did not work. The seats and spaces under them were so small I could not fit my backpack, which I’ve always brought on flights and fit before no problem. The crew were unpleasant and patronizing.

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

Again, multiple delays and I eventually just canceled and drove!

Great crew. We were delayed so that late passengers could get on the flight. Love the bedding in business class. Good food. Great experience.

The CX617 from HK to BKK was delayed more than 1.5 hours.

Horrible - they lied to me about baggage & boarding, even though I specifically spoke to their agents the day before my flight about my issue. When I showed up they did not let me board and stranded me at my airport until I bought a new flight with money I did not have to spend.

All four American Airlines flights I took in last seven days were delayed. Caused me loads of problems, missed meetings, loss of time and money.

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

Flight was cancelled had to move to another gate late again no internet paid for the month and never can use it waste of money

Not being able to purchase my check in baggage online was a negative.

LATE LATE LATE!!! Plagued by late AA flights on this trip. Such a drag. This one was by far the worst.

Not good 😐 Over priced baggage fees Small hard seats No wifi or entertainment options 😕

Didn't like anything!! Horrible flight. Small seating area and hard seats. Butt was sore after 2 hour flight to Seattle No entertainment or free refreshments No wifi or USB charging receptacles to charge phone entoute like other airliners Luggage rates were 3 times as much as competitors. Difficult to navigate online luggue process to pre pay before flight Overall bad experience WILL NEVER RIDE OR RECOMMEND FRONTIER TO FRIENDS OR FAMILY MEMBERS!!! THIS IS A SHAME!! MOST MESERIBLE FLIGHT OF MY LIFE!! AND I THOUGHT SPIRIT WAS 👎 YOU GOT THEM BEAD HANDS DOWN!!

Flight was a little late taking off. Seats are too upright, no ports to charge devices, no wifi, no entertainment

Six hour delay. Poor customer service. No voucher. Bad communication. Missed important appointments.

Our flight was delayed an hour, then when we got to board our flight finally, we were waiting in our seats for take off for 45 minutes before it was communicated that there was a maintenance issue therefore we waited on the plane for over an hour while that was resolved. We did not get to Phoenix until almost 3 hours after we were originally supposed to. This was the first and last time I will be flying Frontier.

Flight was canceled with little warning. Flight was rebooked through Ontario, California and connecting flight was delayed by over three hours. Frontier is living up to their Greyhound of the skies reputation for sure.

I purchased a carry on bag online…was supposed to cost $72 but after a whole slew of bs charges, the total was over $175.00. Because of these hidden charges, I will not even consider flying Frontier ever again. It’s just not worth the hassle. I’m scratching this company off my list forever.

Flight was OK. Seats were good no cell phone charges on the plane no TVs or entertainment.

There were 3 leg for the trip and each leg was delayed by 90 minutes or more. The boarding process takes forever with people waiting on the jetway even though most folks do not have carry-on. The whole process is poorly managed.

Flight cancelled and was told by a rude gate agent that they don’t accommodate on other airlines. Had to wait 5 hours for a connecting flight that had a 7 hour layover. Would not allow bags to be checked early so we couldn’t go through security .Had to rent a car for the afternoon to store bags and get a meal. Also incurred a hotel fee. No apology or reason given for the cancellation- just rudeness.
