Eva Airlines attendants were wonderful. I really enjoyed the hot meals. They always greeted me with a warm smile. I'm looking forward to flying back to the USA with them again!

Eva Airlines attendants were wonderful. I really enjoyed the hot meals. They always greeted me with a warm smile. I'm looking forward to flying back to the USA with them again!

Flight was cancelled which destroyed the rest of our journey.

WOuld have liked coffee or pretzels but other than that, crew and pilot and flight were great. Seat was great, too.

The overhead storage was already packed full when I boarded (I fly peasant class), but the attendant played some Tetris and made a spot for my small suitcase. Thanks!

Snacks for our toddler could have been better, front the standpoint of variety but that’s not any different from other airlines.

I fell asleep and missed my flight and they rescheduled me no problem. Staff was professional and the plane was clean. I was very happy with my experience.

I enjoyed the Starlink access but didn't have much time to use it. It also kept dropping me so I gave up. The food was very good though when I asked for a different "dessert" they didn't have anything. Chocolate Brownie Cookies are not suitable for everyone...maybe children. The flight staff were amazing - at least in First Class! My first time ever! The trip from Boise to San Diego was FAR better than going to Boise.

My flight was canceled and rebooked about 3 times. Original flight had a 50 minute layover. Flight was canceled and rebooked with a five plus hour layover. I demanded refund

Bad experience, delayed take off, arrived late, no entertainment, no food ( have to pay) . luggage claim was horrible, waited almost one hour to get the checked luggage , and my luggage was damaged

Flight from Seattle to Houston sucked the landing in Houston 29 passengers didn’t have there luggage the so called agents that were there to help us did not have a clue as to what to do landed at 2348 as of 0245 was given 1 excuse after another had no customer service representative available to help was very poor customer service and frustration levels were very high would not recommend Alaska airlines from Seattle to Houston Seattle to Ketchikan was good

Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Smaller plane for a longer flight than my first one. Doesn’t make sense.

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.

Delta flights recently are always delayed AND at jfk tney get the gates further away (need To walk 20’ to get to them/all the way at the end of the terminal). Not sure whats happening but price doesnt match experience!

Only freetext wifi was available in flight; browsing WiFi required payment. Since the seats had no in flight entertainment, Delta should revisit this policy on this longer flight.

Because I was moved to an exit row, the snacks in economy comfort, the selection of snacks was better.

The entertainment screens were not working and there was no air condition the entire flight. Very uncomfortable.

Lounge in Lagos is terrible, food on board from Lagos to Atlanta was horrible. Only bright spot the cabin crew were awesome.

I specifically picked out right side aisle seats because my left knee sometimes needs to be stretched. But my experience this trip was that the seats were shuffled and I lost those assigned seats, resulting in me having to sit in a much less desirable position for my comfort.

Great!! I haven’t had a bad experience with them.

Wonderful flight! The crew was good, check-in was good and orderly and the flight was uneventful and good.

The international portion was good. Food and beverage options were good. The sustainable wooden eatery was less than desirable. Your Star Alliance partner ANA provided real silverware. I'm 6'3" & 198 lbs and felt cramped in the exit row. How can that be? Flight attendant all had a pleasant disposition which is always good.

Boarded from a very small gate at LAX. Staff at gate had us line up, then waited 25 minutes to board without a word of explanation. Plane arrived on time then waited 20 minutes for a plane to vacate our gate. Majority of bags arrived after 15 minutes but it took an hour for a small number of remaining bags to be off-loaded despite my “priority” bag tag.

The boarding process on the departure from LA was rather slow even though I was in Group 1. For first class, I was not expecting to have to pay for Wi-fi but I did and then the wi-fi was spotty. The entree was surprisingly good and so that was a pleasant surprise. However, once I got to Houston, it was terrible. Unfortunately there was bad weather but the constant gate changes for my connecting flight was difficult to manage due to having to navigate back and forth between different terminals.

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

The flight was delayed, they didn’t even have water for the toilets or for drinks

Even through the flight was delayed due to storms near IAH The flight was great! The crew was so hospitable and professional

The flight had a delay but I made it to my connection. Flight was smooth overall

No screens or meal options. Freezing cold. Dirty seats. Left late.

Overall flight was ok. Flight attendant was receptive to assisting passengers with tight connections.

This flight 1810 on 7/30 from EWR to DFW got 4 hours delay. this round trip experience is bad, my AA flight 618 from DFW to EWR on 7/28 was redirected to PIT and totally delayed about 9 hours due to mixed of weather and AA IT outage and then on the way back delayed for 4 hours. Lucky, i changed my flight to UA on the way back. i don't like AA anymore. i will consider other airline options in the future.

IT issues created a mess had you change my flight and your system never changed it

The flight was ok, i understand Houston-Dallas is a short distance. The plane is really small: no TV, no snacks, but other than that, all was good. We had a bid delay but luckily it did not affect my connection

My flight was delayed by 8 hours I arrived at airport 4hrs earlier but to see if they can reroute me to get my connecting flt to Hong Kong. They auto rebooked my flt. With no chance. Which I missed this entire reservation through kayak. My next flt they got me on was at 6 am. Misses an entire day of my trip abroad all my accommodations seat assignments were missed and missed adding my TSA precheck to my ticket as well as my vegan meal request so I didnt have meals on any of the flight....so not a comfortable experience. Please help me with accommodations upon my return.

The plane was very creaky and lots of ringing. Plane was dirty and dingy. I couldn't hear the captain's announcements from the flight deck. Not sure if it was the captain or the audio equipment, but good thing there wasn't an emergency where we needed clear instructions. The overhead compartments were clearly full, but the flight crew allowed people to stand in the back with their carry on luggage. Then after everyone boarded, they had to go to the front to gate check their luggage because there was no room for their bags and then they returned to their seats...such a waste of time when clearly the overhead compartments were full when they originally boarded.

I booked an aisle seat and was given a middle. At 6'4" 230lbs, it is not ideal to fly in the middle row for myself and passengers.

Awful. We had an 8 hour mechanical delay- no vouchers and no kind/courtesy/professional representatives in the entire airport. Not only was it a terrible experience for both my 7 year old and myself, I still have not heard back from American about how they’re going to correct it- I’ve sent 2 or 3 emails about our experience- which was just awful. Not to mention according to national traveling laws, we should be reimbursed… but of course they’re not responding.

Overall it was good but not great. The aircraft was an old and seats didn’t recline in business class unless you kept playing around with it.

The plane was subbed for another last minute, the gate was changed last minute. Could live with that but we boarded and there was a delay which totaled an hour in the end. There was a technical issue which meant wheels needed to remain out for ten mins after take off. My USB phone charger was broken as was the headphone jack which meant I could t enjoy the IFE and could use my phone after a few hours. Even the map function on the plane failed to work after a few hours.

The flight was delayed and we were told the airplane is on its way to the gate from the hangar. We were told this for 2 hours and the flight was continually delayed in ~30 minute increments. Then we ended up having a new airplane. The issue wasn’t clearly communicated and it left everyone feeling confused about when we would actually be leaving. Whenever they communicated a new boarding time it felt arbitrary and random. The boarding process was a mess and disorganized, which made it last longer than necessary. Landing was rough. Seats were uncomfortable.
