It was a pleasure to fly with EVA airlines from Taipei to San Francisco.

It was a pleasure to fly with EVA airlines from Taipei to San Francisco.

Flight attendants were very helpful and nice. Would be nice to board on time.

I love EVA airline, but the KAYAK website for not in emergency, urgency and personal issues. For instance, on January 5/2026 with already booked the flight, I have a 15 hours of delay between airport when booked before as my choice. But if I want to go back home (U.S) early, then I have to contact the KAYAK office at I was in other country without phone service and nothing that EVA can do for me. Even I offered to pay more to change from another flight to go to the U.S early, not wasting at15 hours of delay, but EVA could not help me until I call KAYAK at an Island of nation. No office of KAYAK from any nation and times of difference in the world. However, everything and everyone is the best. Therefore, please KAYAK making much more easy for both the airline and passenger in some issues at the middle of nowhere in some country when no need to call KAYAK for some emergency, urgency, sick, etc or personal reference. Please, please, please no need to call KAYAK office for any changes of flights from urgency or private.

My seat arrangement was good with Eva Air. The toilet sanitary was good ( hand wash, face moist spraying, fresh air spray, hair moisturizer). But the Asian movie selection was not great at all.

Don’t preorder the diabetic meal if you don’t have to. Whoever creates those meals thinks everyone loves fish, and hates seasoning. In a world where we can find diabetic friendly candy and low card bread, it’s surprising that places are still serving flavorless gelatin and rice cakes. Boarding in Taipei was chaos. They tried to form a line but didn’t manage it. So once the gate was opened, the line didn’t matter and everyone just mobbed to the front.

Eva airlines has very goin service, despite being low cost. Meals and fin, not amazing, restrooms always clean and staff polite and helpful

Seats. there's no way to go to the washroom when you’re seated in the middle without bothering the person beside you.

Its fantastic!!I like the food the serve in EVA air😊

everything was so good! Especially Food. It was the best I've ever had! However,I requested to add mileage point to Star alliance group ANA; it hasn't been added yet.... 😞

The crew very accommodating and food too is good. Keep up the good work

Delayed, toilets did not flush, pilot parked to far away from Gate

Check-in, boarding and the flight from Phoenix to Houston was quick and easy. The flight from Houston to Shreveport was delayed 5 hours. It was frustrating but I think United handled it the best they could.

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

In Liberia airport 5 min before our departure the airport was closed for takeoff for 30 min. Upon arrival to IAH we didn’t have any available gate and waited taxing another 40 min. As a result we arrived for 1+ h later. The walkway to the passport control in IAH is about 1-2 ml long. After the passport control you have to pass the security check again. Only 3 out of 16 checkpoints were open and the line was enormously long. As a result, even though we supposed to have 2.5 hrs gap in between the flights we missed our transfer. United rebooked us for the next available flight early morning and provided free hotel and meal vouchers through.

United is an incompetent airline. They parked the plane on the tarmac for an hour after arriving because they “didn’t have a gate available” it was actually some sort of lie because as we de planed there were approximately 9 open and manned and empty gates that we walked past. Many people on the flight missed connections for the hour long sit on the tarmac. Utterly baffling and incompetent behavior from United flight ops.

I boarded flight UA#1318 at Sacramento International Airport going back to Houston TX. The flight was scheduled at 5:10am. I was able to check in virtually using the United Airlines app. When I entered the airport, there was no one outside assisting with checked bags as it was for Delta Airlines. Immediately upon entering, there was a LONG, EXTREMELY LONG line to the kiosks to get boarding passes. I stand in line to get boarding passes then had to move to ANOTHER EXTREMELY LONG line to get my bags checked in. While standing in this line, we noticed an agent taking customers to 3 at a time to her station to check their bags in. Lucky for me, she called me back, checked my bags for me and I was on my way. I then encountered another long line at the TSA check and to avoid I ending up having to sign up for CLEAR to bypass it. So glad, I did.,...Both of my flights were great with no issues, butthe check in progress at Bush Airport was so much smoother. Check-in at SMF airport needs to be anaylzed and corrected. Do better United, I know you can....thanks

everything was pretty good. Houston airport is awful. Unnecessarily inefficient; people working there are rude. Badly run

Staff on board was excellent. Positive upbeat helpful- like it used to be.

The Sears in the 800s are not too good perfect Airbus why cant the new 737 fix that

Ot was overall fine. Left on time and had basic snacks. Weather was finicky but that’s not the airlines fault.
