We purchased premium economy seats 9 months ago and got bumped to economy when we tried to board the plane. It was a huge fiasco while they struggled to find us seats. I tried reaching out to Kayak to see how we can get refunded for the extra money we spent on premium but have heard nothing back. It was a 14 hour flight and were disappointed that we lost our seats after selecting them 9 months ago.

We purchased premium economy seats 9 months ago and got bumped to economy when we tried to board the plane. It was a huge fiasco while they struggled to find us seats. I tried reaching out to Kayak to see how we can get refunded for the extra money we spent on premium but have heard nothing back. It was a 14 hour flight and were disappointed that we lost our seats after selecting them 9 months ago.

Flight was overall OK: lovely staff and smooth travelling. The only downside was no food was available on a 3.5 hour flight over lunchtime. Luckily we had realised this in advance and brought our own bento.

The whole flight in Economy was great, the crew were just amazing and the food was great as well

Crew went out of their way for me, not often

Lots of legroom for a small flight. There was in flight entertainment even though it is a short duration. We waited on one passenger to board for a long time after everyone else was on.

Domestic flight, 1hr 20mins from SFO to LAX, which takes about probably 40-30mins on air.

Easy if you are a United States Citizen, when you go to US Border & Customs, bring your Passport if you arrive Internationally. Remember to pick up your check baggage before moving into domestic flights, as they will check the tag for the plane you are boarding in. (They will check your baggage again). Bring your ID/DL (Real-ID COMPLIANT) with you to pass security/TSA, passport works too. SFO is pretty strict as well as LAX. Domestic flight, 1hr 20mins from SFO to LAX, which takes about probably 40-30mins on air.

At Fukuoka, check in counter stuff was no experience , took long time and took out our preserved sheets to change to emergency exit seats without asking. The flight was late and we missed the flight to go back to SF. My luggage was broken. I had a terrible experience.

Chair was broken. Crew was awesome. Food was eh. Dinner food not so good the sandwich was good ( for airplane food) headphones hurt my ears. It’s hard because no one has plug in earphones

Fast boarding. Cabin temperature was a bit warm, but I guess this is the standard in ANA. The Room seats are spacious, but not long enough for me.

Underpricer was terrible. They wanted to charge me $150 for a seat asignment. Kayak is responsible for letting this happen. Please let me know if this is going to happen in the future. If it is i will not use kayak in the future.

Checking in was hard because we had to enter our middle name with our first name and wasn’t told to. The representative from underpricer investigated it and called me back. We were very appreciative for him.

One of the best economy flights I’ve ever taken .

Minimal legroom. Most passengers are respectful and don't recline. Outrageous long walk from Terminal One to Terminal Three.

Good, not excellent. We’re not informed about mattress pads in business class. My partner ordered food and didn’t get it

I said the boarding was just par with other airlines, but I can't think of a way to improve it.

The flight was canceled, and the airlines stated that they don't know when they can put me on another flight. I had to purchase another flight from a different airline. I am now having issues requesting a refund. What a nightmare experience, I will not refer anyone to this airline.

Enjoyed flying Japan Airlines! Staff were all nice & flight was comfortable.

It was a quick and comfortable flight. There was no entertainment or food so I gave them poor marks. I wasn’t really expecting either so wish there was a NA option. Great flight with more leg room than my longer, overseas seating!

Particularly meals were great. Service’s were excellent as usual. .

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

Booked a united Air flight with option to pick seat , then found out was on an Air Canada flight with assigned seat , then they wanted a several dollar charge for some 25 cent value entertainment listening ear device

It was fine. The flight attendant appeared to be in a bad mood but everything was fine.

Waited for our plane from HNL so we didn't miss connection. AMAZING Service for that, then really clean plane. Nice airline attendants.

Seats are outdated. Entertainment relies on personal device. Boarding was delayed due to inaccurate passenger tracking, resulted in late arrival at Reno.

Excellent staff helping my 96 year old senior promptly with her oxygen needs

The crew and flight was amazing. I haven't flown United in years but plan to switch to you being my main airline

Basics were there, but a 5:15 flight with almost no food ans no entertainment, it is quite long.

Moody attendants that can barely look up at the passengers. I’m all for people having an off day, but you can tell some Untied Airlines Employees have lost their zeal for their jobs

Some of the issues with my UA flight to a connecting flight: United said the SF to Frankfurt flight was getting late making us miss 10:50 flight and could only put us on a flight that left at 4:15 PM from biz to coach. then they canceled the ticket on the connecting flight. I didn’t have a seat, etc., etc., and over an hour dealing with UNITED blaming Lufthansa and Lufthansa pointing to UNITED. The flight itself was fine (food sucked) and we landed in time that I could’ve made the 1050 flight. but the LH gate agent said I couldn’t get on because United issued the ticket and only they could change tix back. Gave up and wasted the next five hours plus of our vacation and ended up being totally wiped out by the time we reached the hotel.

It was for the most part a 10/10 they said they had entertainment options but all they had was old movies for streaming from the mid 2010’s so like 10 years ago

all good for a very budget flight - well priced and excellent service. Will fly again

Couple of the crew members were really nice and the rest are really rude and didn't help when we needed help, food was not worth it at all and most importantly there's no even entertainment system other than a very interruptive and slow internet and some movies.

I appreciate the economy price of the tickets. The long flight made the comfort level on the lower average side. Wi-Fi connection was not consistent but working. Overall, I would fly again with zip air but next time get the flat, premium seats with the amount of money I would save otherwise.

Comfortable seats and lucky no one was in middle seat. No water on the plane. Plane was on time and staff was fast.

You get what you pay for and nothing more. Wanted a cheap flight and that’s exactly what I got, though it’s human nature to wanting to feel like you got a good deal as well. There was none of that here. I was cheap and they were too. Got to my destination safely and that’s all that really matters.

Nice service. I wish it could provide hot water on the flight.

internet didn't work. No offer of drinks or snacks.

Flight was seamless. Free wifi helped pass the time. Food was okay, just make sure you pre order or pick something up from the airport

Internet connection very poor, means you can not even order items through their own shop.

Crazy seating issues. We got seated far apart. Offered middle seats at a premium rate. Why is a middle seat now the expensive seat? Baffling.

The boarding process was a nightmare and though we were traveling business class, we were in Group 2 and the organization was terrible. The Business Class on this flight was crowded and did not feel clean and nice. Overall, I would not travel Business again on the American Airline flight through British Airways Not nearly special enough for the considerable cost .

Not too impressed with them to be honest. They had forgotten my gf meal, despite the fact that the app had notified me that it was sorted. Apparently there is a ‘glitch’ in the system, according to one of the stewardesses, and has been for a while. Also the legroom in economy is way too small (and I’m a slight person) and are very uncomfortable. An extra Internal flight I booked via the app, had not even given me the option to order a meal, so was unaware of that and left without food on a 9 hr. flight !! Don’t think I’ll use AA again after this.

The flight was uneventful. What was a problem was I was delayed getting home one entire day because the flight from Sacramento was delayed. That made getting to my connecting flight impossible. I had to stay another night at the hotel and incur that expense as a result.

VERY disappointed at the agent checking in my luggage. I know that the weight limit is 23 kg, a little over 50 pounds (50.71 pounds). Yet the agent kept repeating "50 pounds". So I said, the limit is 23 kg, and she had the audacity to say 'no, it is 22 kg!" Imagine my surprise. Was she ignorant or was she poorly trained? Not sure. The boarding process was pretty good. The speakers were loud enough so I still could hear them despite inconsiderate passengers continuing to speak while the announcements were going on. During the flight, the teenage girl sitting behind me kept pressing her feet to the back of my chair. I turned around several times, yet she did not get the hint. I did not make a fuss since I sense I had a bad streak that night with AA, so I just did the best I can to lean forward and not let that bother me.

Seats were very uncomfortable. I paid extra for a seat with more leg room, the seat was no different than a seat at the back of the plane. Flight attendant was rude.

Flights were on time. That's the main consideration since I had to change planes. The entertainment was whatever you bring with you and the food (in Economy) is non-existant. Neither of those was a surprise.

Mobility assistance at DFW is A JOKE!!! Totally disorganized, ineffective and annoying. Ended up having to walk and find our own way for a good part of the very, very long walk between gates. Worst assistance I have ever experienced.

Newer Aircraft have more amenities, but the JAL flight crew and ground staff are top tier and provided the best customer experience I've ever had on a flight!

This is a new route from Philadelphia to Naples. It was sold out. The team on board was excellent. I’ve flown this route twice this year and the flight has been excellent. I hope American keeps the route.
