It was a good experience! Thank you:) No sparkling mineral water… 🥲

I don’t like it stuff not friendly and no one help for my mom she 82 years old lady I requested wheel chair but no one provided and no one help.

I loved that the checking in process was seamlessly easy and user friendly. The crew was very nice and professional. Unfortunately, we were seated in the back of the plane across from the bathroom. There wasn’t much room for leg room and comfortability. Alongside, we had to listen to a baby crying up and down the aisle way for the entire plane ride. The turbulence of the plane landing was rocky. Overall, the experience with Alaska was just okay. We made it home alive so that’s always a positive.

Although the plane was delayed , I appreciate the food credit.

Seat 6F was very good, but had loud engine noise

It was prompt. The only problem was that there are electric outlets at the seats, but they're on a slant, so my computer charger just fell out if I wasn't holding it. Flight attendants were fabulous.

It would be nice if these was tv😊not everyone has tablets ! But l had a very nice flight,way better then so many times. Thank you 👍

I was seated at the back of the plane and the flight attendants were fantastic. I did not get food so can’t say. Thought the movie selection was lean.

I think in 6:15 hrs flight the airlines should give some meal and not just couple of cookies People reach their homes at around 12 mid night and then they have to make dinner and eat I started my home at around 5 o clock and no food till 12 midnight You should give some reasonable meal in flight Thanks

Good flight. Pilot kept us well informed and attendants did a great job. Negatives:,1) little snack packs are far too expensice; 2) arrived early but waited 1/2 hr+ to get to our gate to deplane!

The Air hostess were very rude on my flight from Houston to Austin . Their regular communication itself felt a they are shouting at people.

WiFi was not working and didn’t have a beverage service

The charges were ridiculous for an hour flight and the turbulence was very scary.

Great flight. Outstanding Service. Southwest was able to put us on a direct flight to Denver when the connection could have been affected by a later arrival to Baltimore. The direct flight was less expensive that the flight with the connection in Baltimore.

Flights delayed by 4-6 hours. Boarding was a mess and unclear. Bags were not at arrival airport and had never even been put on the plane. No idea when I’ll get them. Don’t fly into Denver!

The plane arrived 25 minutes late, and the Wi-Fi was slower than it usually is.

Flight was on time and the crew was very nice.

Flight was delayed for 1 hour. Otherwise it was a fairly normal Southwest experience

Main flight attendant made light of the delay and presented some humor to lighten the tempestuous situation. Delayed flight took off 2 hours after scheduled time.

More assistance and clarity for travelers with gate checking and lap children

I thought the service was very nice and pleasant. There were no hiccups and no issues so overall a good experience.

One of the flight attendants was a little cranky. I appreciated the free wifi and plug to charge my laptop

The cabin temperature was nice and cool. The wifi was not working.

I really liked the legroom. I am 6’4”.a at For some reason our seats were not together and using the app to fix it didn’t work. Passengers were nice enough to move for us but you should absolutely ensure a parent sits with their child.

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 .

5 hours of delay that could've been much shorter if Delta had taken the 1 hour delay they imposed on the flight before boarding to run any of the plane checks required for flight to find the hydraulic issue that required nearly 3 hours to fix. $24 of meal credit buys a sandwich and a soft drink. Poor communication within the terminal about what gate we'd be re-boarding from and when we'd be re-boarding.

Seats are much much more comfortable than United, which is what I usually fly

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Crew was not friendly when I went to request a seat change.

Comfort+ on delta was excellent room for a 6’4” male. No one issues. Staff was great. Flight was bumpy but the pilot did everything he could to make it comfortable. Internet went out half way through the flight. I am glad I didn’t pay for it. But that was a huge issue for users.

Terrible boarding and first class experience. Nice staff but overall disorganized, dirty plane.

The flight was delayed significantly and we sat on runway after landing for awhile. Best thing was the flight attendant, Jenny, in first class, who was very professional and attentive. She was excellent - the rest of the flight was not.

Early departure meant on time arrival. Only real problem was free internet had issues, although chatting with the internet help desk (you can do this via aainflight.com) got the issue resolved.

The staff and service on American Airlines were truly outstanding. I had requested wheelchair assistance for my mother due to her knee issues, and the team went above and beyond every step of the way—from boarding in Boston to our arrival in Chicago. Their care, professionalism, and attentiveness made the entire experience smooth and stress-free. I’m very grateful for the support they provided.

Found that the plane used for this short flight is smaller and therefore the seats are really squeezed tight.

Great experience. Good dinner and service. FA's were very nice and attentive.

Jill was the flight attendant in first class she was fabulous!! Best flight attendant I have had in years.!! And I fly every other week. Other can learn from her!!

The flight was significantly delayed for 6.5 hours because of snow. There was no communication once the plane returned to the gate regarding when the flight would resume. Other flights were departing while our flight was being unloaded for reasons unknown. Our flight also seemed out of the queue regarding further deicing, refueling, and waiting to Taxi to the runway.

After the door had been closed, the cockpit makes an announcement that catering is running late and it is not the airline's fault. It is their fault in the sense that we had to sit for 2 hours or more when we could have stayed in the terminal. Poor communications between catering and airline. This caused a young man to lose his temper and he went storming out hitting objects. He had complained to the gate agent that he had already waited at the gate 7 hours and when can the airplane leave? Airilnes do a poor job of explaining delays, maintenance issues, etc. whereas being truthful may gain more sympathy or understanding.

The foot ottoman cushion was missing on my business class seat.. the hydraulics is on its last leg & seat cushions do not have support or paddling. Heavily dented by butts

Whole experience was poor. Delayed 2 hours. Lied about the delays. Was all jet blues fault and tried to blame on air traffic control. Sent out other let trips and wouldn't allow people to switch aircraft.

It was fine for what it was. It’s not luxury travel but it was efficient, for the most part. Having my carry-on transferred into luggage however, was unwelcome.

I was seated next to an autistic child who was out of control and had a child behind me kicking my seat for most of the trip. I will never fly JetBlue again. Ever. I don't care how cheap it is. It's terrible.

Great price, easy check in, love the free drinks and snacks, and nice crew. The only negative part was waiting for your seat assignment 5 minutes before boarding, and the seats are a bit uncomfortable.

All airline travel outside of First or Business class is an ordeal to be endured. This trip was ok, small o, small k.

Flight emergency landed in Chicago due to “Odor” in back of plane . Had to buy ANOTHER TICKET to get to Boston cash out of my own pocket . Then they would notchange my return flight time without a 400. Charge!!!! Insulting.

we were an hour delayed after boarding and given no reason. Headsets cost money. Also there were openrows with no one setting in them but we were told we were not allowed to swtich.

Very pleasant flight attendants. Gate crew rather loud chatting with each other.

Service for food to our seat was a bit slow. Snack choices were just pretzels or baked chips. My seat cushion was not attached. Other than Barbie, video choice were not very good or current.

almost 4 hour delay as they over booked and had to wait for 8-10 volunteers to agree to travel next day.
