The type of the food requested (Asian vegetarian) was not properly met with. They have very limited snack items that may compensate for the main meals.

The type of the food requested (Asian vegetarian) was not properly met with. They have very limited snack items that may compensate for the main meals.

The quality of the food is pretty good. Thank you, EVA Air.

A wonderful new plane. Great menu. Professional service. You and your wife were completely satisfied.

Pleasant crew. Very long flight, a bit uncomfortable at times being seated, but not too bad.

No ice for the drinks. Only gave a half a cup of your beverage. Not enough water. I got very dehydrated.

Eva is one of the top airlines in Asia... but often are over priced. Finally found a reasonable rate.

My original flight was rescheduled & EVA did a good job rescheduling my flight & connecting flight.

Polite hard working crew. No complaints really. Meals were not to my liking.

Everything was fantastic! The crew really went above and beyond to make it a great flight. I felt cared for with EVA.

t and I Flight crew did excellent job taking care of us and feeding us and staying professional. The boarding was delayed by an hour and then extra security measures were taken. No real explanation except for they said it was more of a maintenance dey

Great service but food taste and options have gone down a few notches.

This airlines is always my favorite. Very consistent customer service and food is good. My last flight with them, I had no idea we landed because it was just that smooth of a land.

At least it was not very cold inside the plane. I noticed there was now a bidet in the bathroom and that’s good! I didn’t like the window seat. Flight was smooth except for 1 turbulence. Plane was on time. Thanks. Food was not that great. Miso and green tea were good! As usual movies were old and there were no changes.

Food as always. PA was not clear, especially the English ones. Very limited Hollywood movies. Unlike the first flight I had, this plane has less leg room and less room for my under seat baggage.

Food is lagging. Very poor choice. Like vending machine fast food.

I didn’t like the check in process I had to check in at the counter took too much time . Didn’t give the upgrade my seat .

JAL is a flawless airlines. Perfect customer service. On-time boarding, clean airlines, and incomparable in-flight dining.

It was one of the best experiences. The staff were amazing. JAL is my second favorite Asian Carrier I have flown on. Korean Air was my first. Thank you JAL for bringing me home safely and for such an amazing staff and service.

JAL is quite nice in business class. Comfortable, spacious seats. Their entertainment, especially their film selection, isn’t that great though as their are not many new releases like some airlines offer their first and business class customers. . Food is excellent and the option to order on demand is always quite nice, which JAL offers. Flight attendants were very friendly and kind. Overall very good experience with JAL.

Very comfortable unlike my first trip where they switched my flight from JAL to AA which was a disaster!

My experience with Scoot is very good. Will have no issue flying with Scoot again.

My overall experience with Singapore Airlines is great. Will definitely fly Singapore airline again.

Good flight. Fiod was ready a bit late hence a hurry to finish before landing. Excellent crew and service

Great to have actual hot tastey meal on a flight. Well done

Cabin Crew always friendly and helpful. Seating cramped - foul smelling from toilets, high risk of disease. Guard personal property such as expensive sunglasses Coffee always awful and cold Meal trays toddler sized Not worth the extra cost to fly SQ - use a budget airline, same if not better experience

When boarding, after business class should be premium economy, but economy class already lined-up at the gate blocking premium economy to board. Singapore airline crew should done a better job to organize this chaos :( Thank you.

It seems paying premium economy does not make difference with economy. No priority boarding, not worthy paying extra$$$ for premium economy.

A pc of cake or biscuit at least. The airport was like a maze need to take another bus to the main terminal to immigration.

Flying with Singapore airlines is always excelllent - the crew are lovely and the food too is great. It’s my number 1 airline

They were able to assist my elderly father and myself after not being able to check in to scoot. The counter service was phenomenal. They did what they could to get us on the next plane so we could catch our Connecting flight. Scoot closed early on us so we ended up missing our flight.

Surprisingly easy! I was hesitant to try this, but the cost swayed me. I actually felt like I had less stress than all the taxiing and possible delays that occur with short regional flights where you spend less time in the air than getting to and from the plane..

It was okay, no wifi or entertainment real disappointment. Staff onboard not very friendly.

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

It started with multiple delays, cancellations, re booking, 5 hour lay over and finally on a plane from Chicago to Pittsburgh. Gates, times, etc were changed multiply times. Once on the plane, staff was fine, but built in tv did not work and could not even turn it off. Light at eye level the entire trip, so sleeping was near impossible. No snacks or drinks given.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

Only water and pretzels served on six hour flight. Did not see crew rest of flight. No video screens and so no wired audio. Poor sound on plan so did not understand anything said by crew. This is a safety issue. Electrical socket did not retain charging block so could not charge phone. No video screen so could not watch movies. Phone is not a substitute.

It was fine. Flight was on time and arrived at destination with 15 min to spare.

My bag was lost with my medicine and I am very inconvenienced. I don’t know what happened, however I want you to do a better job on getting people’s bag back

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The food that was offered based on class level of your ticket was absolutely ridiculous and disgusting. They didn't even hot tea to serve, the food was horrible. On our departure flight I was seated in premium plus economy and considering the cost of the flight the food was literally some of the worst I've ever eaten. On the return flight I sat in economy with extra leg room and was given a thin little throw "blanket" and a flimsy little pillow. The air condition was on artic and the seating arrangement wasn't really worth the money. The seat didn't recline good enough and the foot rest was laughable. Total waste.

Use planes with TVs on flights over 4 hours. The free entertainment was a cheap in between solution for a very long flight that you don't even bother providing meals or decent snacks.

Even though we left CMI late, we mostly made up the time.

Delayed almost 4 hours for a 45 minute flight with no explanation.

Again, multiple delays and I eventually just canceled and drove!

Great crew. We were delayed so that late passengers could get on the flight. Love the bedding in business class. Good food. Great experience.

The CX617 from HK to BKK was delayed more than 1.5 hours.

Horrible - they lied to me about baggage & boarding, even though I specifically spoke to their agents the day before my flight about my issue. When I showed up they did not let me board and stranded me at my airport until I bought a new flight with money I did not have to spend.

All four American Airlines flights I took in last seven days were delayed. Caused me loads of problems, missed meetings, loss of time and money.

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.
