I was traveling with my parents to San Francisco. One of front counter employees saw my parents are senior, he let us boarding first which was so thoughtful.

The food was good but needed more taste, or it would have been better if the airline had provided salt and pepper.

Alaska is always a great airline, friendly, clean and usually on time.

Friendly crew and super clean cabin. 💺 are comfortable as well. I love the ambient blue lighting.

Cathay Pacific is an excellent, well-maintained airline. While I too would love to fly first, or business class, I did not. I actually had the dreaded middle seat in the middle row, and yet, since I am an inquisitive traveler, I introduced myself to my row mates and had nice chats with both until lights out. Pro tip: Bring a donut travel pillow no matter where your seat is! The flight was smooth, the restrooms clean and the staff courteous and efficient. I gave the comfort level a 4 because of the reasons listed above. The airline meals... let's face it ... it's airplane food but CP does a good job in making it as edible as possible.

Quick, efficient, incredibly kind staff. It was a short flight (50 min)but still received beverage service. Treated my 5 year old like a star. Just endlessly appreciative.

It was a good flight, crew members were friendly. The flight was smooth and overall a great experience.

What was the reason for the flight delay? The plane was there in plenty of time!

No snack offered, leg room really needs improvement. N/A on entertainment; none offered or needed.

Great ground staff - made boarding smooth for my family , helped us be seated together. Cabin crew was very friendly.

Only one side of the heafphone jack work. Crew was friendly and helpful.

Great. Flight departed early and arrived early. Deplaning and baggage claim ww were quick.

Don't waste your money or points on first class. Delta first class is a joke. The seats were rickety, the food was awful, and nothing worked, wifi, my light, the power plug - and it was dirty - the fold out table was gross. For 2-3 hours, tough it out in Economy.

They separated our seats and moved us to the back of the plane. Hundreds of dollars and thousands of miles used and this was my platinum member experience.

Flight was changed from departing from Boston to departing from Detroit.

AC barely worked on a 50 minute flight. It was very warm the whole flight. Flight was very bumpy and hard landing.

Got on the plane and then needed to deboard the plane because they didn’t have any pilots?

The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.

Rough day of travel all the way around. Wrong info given to us multiple times and mistakes in their booking making our trip 10 hours longer than planned. I’m bummed because I fly Delta all the time and love them. Mistakes happen. Just bummed that this was a rare trip our whole family was traveling together.

Meh. A late flight meant I missed my connections, and a 2pm LAX arrival turned into gettin in after midnight.

Communication with the customer and stay is important. Staff off with a minor inconvenience but it worked out of course. Also this was a very old Mint Class plane. They snuck this one in on us. The updated aircraft are much better.

The flight itself was fine, but the boarding process was extremely frustrating. There is no one scanning boarding passes - passengers just scan themselves and enter the jetway. By the time my husband and I got on the plane and were halfway to our seats they determined there were too many bags on the plane and everything at that point needed to be checked. This created a lot of unnecessary chaos. They should have alerted people before getting on the plane that they would need to start checking bags instead of waiting until people were already on the plane.

Like the space, did not like the snack options, there was no power outlet in seats, no entertainment, no flyfi.

I volunteered to let them put my carry on suitcase in the baggage storage area. But when we landed I was told it was being unloaded IN A DIFFERENT TERMINAL! I had to walk (painful for me) a long way to retrieve my bag and my ride had to move from the waiting area they were in to a totally different one. Not happy.

Overall fine but both ways for this trip was delayed.

I had back trouble prior to my flight and everyone was great about helping me.

My tv was broken on the flight which is disappointing when you pay for a seat and expect a service

Always delays from Boston to Salt lake but this time was very long. Don’t understand while they board the passengers and then make them sit in the plane

The boarding and flight were ok, but there were several painful issues. The flight was 3:20 in the air and almost four hours door to door, but they only had snack packs on the plane. They really need to have food on longer flights or make it clear to everyone that they won’t have food. They also advertise free WiFi, but it did not work for 90% of this flight. Again, almost four hours door to door. If I had known I was flying spirit for JetBlue prices then I would have planned differently.

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.

Cabin was pitch black, even during meal service. The reading lights for seat 2E/F did not work, and seat 2E did not recline.

Was realllly smooth. It was delayed but we were well informed.

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.

To san Francisco it was ok. From sf to Manila it was horrible

Awful, rude staff. Their abrasive comments are unnecessary. Most seek a frictionless experience and will cooperate if you ask. Additional childish bullying of customers is not acceptable or tolerated. We had the same problem with our departure flight. We will never fly United again.

Very poor the plane itself was really old, slight smell that couldn’t be named. I didn’t even get a boarding pass UNTIL AFTER clearing security! Even then, they said when I get to my connected flight I’ll get my 2nd boarding pass there! A bit ridiculous!

No cooked food. Crew was not friendly and not that helpful

Boarding was efficient. Crew was not pleasant and skipped me during a round of beverage service. Older plane with no seat back screens and I couldn’t connect to wifi or their entertainment offerings.

United Airlines was fantastic, however, UnderPricer was a nightmare. I got to the airport 4 hours before my flight. We are moving to New Zealand so had quite a bit of baggage (16 checked items) and so wanted to have plenty of time to get everything taken care of properly. When I went to check in they (United) could only find a ticket for me. The 5 tickets for my children were never officially ticketed. I called Underpricer and they told me it was United's fault and United told me that Underpricer just needs to reissue the tickets, but they refused to. I asked the Underpricer agent to transfer me to his supervisor as I was not getting the help I needed. He told me the supervisor was busy but that he would call me back in 30 minutes. 30 minutes came and went with no phone call. After an hour I called Underpricer back but they would not let me talk to the person I had talked to before, just told me that he was talking with the supervisor and technical support. I called again an hour later, was told the same thing. I tried again later, with only about 30 minutes until my flight was scheduled to leave (meaning I had been at the airport for more than 3 hours with my 5 children trying to get ticketed and board the flight). Also, my husband had moved to New Zealand 3 months prior, I haven't seen him in 3 months, my children hadn't seen their dad in 3 months, we were all extremely eager to get on that flight and get to New Zealand. The situation with the tickets did not get resolved until after it was too late to check our luggage and board our flight. We were devastated. My 11 year old son was in tears at not being able to be on his way to see his dad. Thankfully we were rebooked for the next evening, but that night it felt devastating. We'd been at the airport for 4 hours waiting. My in-laws waited with me and then helped me reload all our baggage and took us home to stay with them for the night. On the newly booked flights we could not sit together - my children were spread throughout the plane. So, even though I had paid extra to select our seats after buying my seats from Underpricer only two of us were able to sit together (thankful that my 11 year old wasn't all by himself, but not happy that my 14 & 16 year old daughters were seated by strangers). I really feel that Underpricer should refund me what I paid for the seating ($120 USD). It was a very frustrating situation and I plan on never using Kayak or Underpricer ever again.

The lady at the check in counter wasn't helpful

RE Food: Wish there was a choice for No Rating. Flew from Honolulu to Los Angeles on a Red-Eye flight (11:00 pm to 7:30 am). Other than a package of cookies with a beverage choice offered soon after take-off, and a beverage choice shortly before landing, no other food choices were offered. Everyone slept or rested for most of the trip. Nothing to rate. RE Entertainment: Everyone was sleeping most of the flight. Only saw one passenger watch about 30 minutes of entertainment on his iPad. I never attempted to access any entertainment options.

Baby cried a lot. Nothing anyone could do about it. Just part of flying.

AA is fabulous. However , Iberia cancelled our Boston - Barcelona flight the morning of the flight - 9/16/24. This was almost a week ago and we have still heard nothing from Iberia/Vueling. Found out from a kayak email that morning that the flight was cancelled. Iberia Customer service reps wouldn’t help us and said to call Vueling. No one answers phone at Vueling. Terrible wild goose chase on DAY OF TRAVEL. AA came to our rescue.

Boston ticket agent Cheryl Porter is WONDERFUL. Our Iberia flight to Barcelona was cancelled the morning we were scheduled to leave and Cheryl was our super hero - she found us seats on a flight to London and on to Barcelona. Truly a “can-do” attitude which we appreciated so much after the Iberia ticket agents told us there was “absolutely nothing they could do”. (As did the customer service agents at Iberia’s call center) Ms Porter is truly a wonderful person who genuinely cares about travelers!

The boarding process was such a chaos with everyone crowding at the gates. There was no structure. The onboard crew were fantastic and very good.

For coast to coast travel the A321 and even the NEO, even in first class will never be excellent. That would take a B787 or 777 to accomplish.

The flight crew was fantastic! Which the seats had a small TV.

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

also wi-fi never worked attendant said satellite coverage is spotty over water ..... but we were over land!

I was unhappy with having the seat I chose changed at the last minute. I was moved to an aisle seat which did not recline and was next to the bathroom. The bathroom odors made the flight entirely unpleasant. Having carefully chosen my seat months before I was not pleased with my AA experience. In addition, they ran out of tea during flight service, really?
