Excellent flight. The crew was exceptionally attentive and organized. Attention to details is unmatched.

Read more Austrian Airlines reviews

Excellent flight. The crew was exceptionally attentive and organized. Attention to details is unmatched.

Loved the courtesy and punctuality. Very professional and most importantly on time.

Great! They got my vegetarian meal right, flight was comfortable, they helped store my heavy luggage. Pleasant crew and flight staff.

I did wish they would give us the entire little bottle Bailey's instead of just have 1/2 bottle at a time

They had me unpack a handbag 2 lbs overweight into another handbag 8 lbs underweight for a Bible.

Accessibility serious problems in Viena airport making it seriousely difficult in in-between gates and boarding travel. Pretens of breakfast and service care in the economy pathetic.

One thing I really liked about Austrian Airlines was that the flight attendants were very kind, and the in-flight entertainment offered many choices. One thing that could be improved is the meal service, since only a vegetarian option was offered — it would be better to have at least two choices

Despite the booked seats in front of the land we were moved to the back of the plane even first like 8 lines were totally without pasangers. When I tried to sit on empty seat flight attendant asked me to go to my dedicated seat in the fully crowded back of the plane. She was not able to explain why. Food was very poor on flight LAX - VIE.

Landing was a little hard. Food was not great My prior review was for the flight to nyc too

Five star experience all around except for my seat, which was broken. It would only go down 70%.Of the way. It defeats the purpose of buying a business class ticket if you don’t actually get to lay flat..

United has come a long way, it’s been a fantastic experience traveling with them.

This flight leg was fantastic - super comfortable and a great selection of things to watch on the TV. Staff were excellent, really above and beyond.

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

After boarding the plane in Chicago, the passengers were told that there was a technical problem with the plane. Passengers remained on the plane as they tried to fix the problem. After what was probably an hour passengers were told that there was a need to change planes as the problem was not solved. Passengers disembarked and boarded another plane. After taxing to the runway and waiting for takeoff, passengers were told that owing to the thunderstorm the flight was unable to take off but would try and reroute. After some time passengers were told there wasn't enough fuel for the new route and the plane had to return to the gate for additional fuel. after another log delay the flight got underway. On the plane there was food, drinks, ice or entertainment. We were a glass of water, which appeared rationed. Flight arrived about 5 hours late. The pilot was fantastic and communicated with the passengers throughout the ordeal.

Excellent all round, first time flying United. App is very helpful.

Efficient all round, very good crew. Short flight so the food, of course, was just snacks

Better WiFi. I cannot understand that in 2025, United is so behind on a technology that is now a necessity and still painfully unreliable, slow and keeps disconnecting.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

Excellent experience. Starting with the agent at the Premier bag drop who noticed I was very early for my scheduled flight and offered to rebook me on an earlier flight with my seat preference. She would not let me leave the counter until she knew that all of the changes and new boarding pass showed up on my United app. At the gate, the flight boarded quickly such that we departed early and the flight was smooth. We arrived 20 minutes early at ORD and I was able to be home in time for dinner. One of the best flights I've had.

The seat space seemed small especially when the person ahead reclined but other than that, very good.

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

Food was poor quality and the screens for entertainment didn’t work properly

It was a short flight, everything was good with it.

I darted through the Frankfurt airport to make my connecting flight. I asked if it was a possibility to upgrade and the agent did. This was the kindest gesture and it made up for the previous delayed flight and distress/anxiety of anticipating that Zi was going to miss my Frankfurt-Chicago connection. I cannot express my gratitude for the upgrade.. I am 5feet 10 inches do the leg space was amazing.

I meant this flight was not good, the one from Tirana to Frankfurt was better!

I was very grateful for Lufthansa's role in organizing mobility support. The touchscreen on my seat was faulty: slow, stained (I couldn't get it clean), and glitchy. This made selecting movies extremely time consuming, and twice I had to start all over from the beginning.

The crew was the best I’ve ever encountered. Business class was spacious, immaculate, and very modern.

I wish seats were not reclinable. It's so claustrophobic when the person in front of you spends most of a nine hour flight leaned all the way back. The crew was really nice though and the dinner (red Thai curry) was pretty compelling.

Our flights were severely delayed, then canceled and we had to fly out next day with no sleep accommodation help. This led to our baggage being lost and the service reps after baggage couldn’t be bothered to help. They kept sending us to different counters when we were at the right counter to begin with. The only saving grace was the angel woman supervisor with blond hair who helped us put in a missing baggage claim.

main meals are horrible but then you dont fly for the food

It was good. Couldn’t Check in online and select seats

It was great. Enough space and room for legs . Great service to.

⭐ British Airways Review — A Journey of Highs, Lows, and Lessons ⭐ I recently flew Business Class round-trip from Boston to Mumbai with British Airways, and my experience was a tale of two extremes — from disappointment to exceptional service, and then back to inconsistency. Boston → London: A Surprisingly Poor Start My journey began on a disappointing note. On a 6-hour Business Class flight, I was surprised to discover that there wasn’t a single proper vegetarian meal option available. I was offered a few bakery items only after repeatedly requesting something to eat. The flight attendant shrugged, offered no solution, and eventually — quite literally — threw some bread at me after much delay. This was not only disheartening, it was extremely surprising given my wonderful Business Class experience with BA last year. I stepped off that flight genuinely hungry and had to make a mad dash to the lounge just to get a proper meal. London → Mumbai: A Complete Turnaround The next sector restored my faith in British Airways. The entire crew was warm, welcoming, attentive, and genuinely caring. A special shoutout to Phiroze and the entire team serving the Business Class cabin — their professionalism, hospitality, and thoughtful service were extraordinary. They truly embodied what makes British Airways a global leader, and I am deeply grateful for the experience they provided. This is the BA I know and love. Mumbai → London: A Strange Meal Schedule This sector was generally fine, but the meal timing was puzzling. Lunch at 10:30 AM — for a Business cabin — felt unusual, and most passengers, including myself, barely touched it. The rest of the service was smooth, but the scheduling definitely needs a rethink. London → Boston: Mixed Experience Again The flight itself was decent, but the Business Lounge at Heathrow for this leg was a letdown. Arrived during lunch hours: no hot vegetarian options available Lounge area: dirty dishes everywhere Even after politely alerting the staff, the dishes were ignored and left uncleared For a premium cabin passenger — and at one of the world’s busiest international hubs — this was disappointing. Overall Impression My journey with British Airways felt inconsistent — two great sectors sandwiched between two that fell short of the BA standard. When BA is good, it is world-class. When it misses, the gap is noticeable. I genuinely hope the airline takes this feedback as constructive insight. I continue to believe in British Airways, and I commend the outstanding crew on the London → Mumbai sector — they were the highlight of my entire trip. With a little more focus on vegetarian meal availability, lounge service, and consistency across crews, BA can ensure every Business Class passenger experiences the premium journey they promise.

We were in business class and I had seat # 1. This was a night flight and after dinner was served, lights were dimmed and I went to sleep. The crew were loud and noisy so I didn’t get much sleep. I expect the crew to enjoy themselves but would Appreciate some decency in staying quiet while the passengers sleep

Have travelled business class with other airlines who profess to be the best in the world. They can however not beat the service and comfort that BA provide.

Well unfortunately our connecting was cancelled and next flight delayed. Was in airport 9 hours. Flight itself was good. I’m sure it was a FAA problem.

Great on board entertainment Tasty food Cattle class obviously crammed but not as bad as shorter hall flights

I was attacked in the Miami airport and the staff did nothing. On my flight from London to Miami one of the flight attendants screamed at me and demanded I keep my seat in the upright position at all times during the fight so the man behind me was comfortable for the flight. I will never in my life use British airways again

Logan gate staff was unhelpful. Arrived early, come to find out the airbus scheduled was reassigned and I did not have a seat. The desk agent spoke to his supervisor who instructed him to give me a boarding pass to get up to gate area, he was polite. At the gate the fellow was sitting to the side with two other BA staff . I asked him if he could help me, his answer was” we are on a break, we are closed” then turned his back. I am almost 70, drove 4 1/2 hours to Boston and had been looking forward to this trip for 5 months. I have worked in service many times in my life and this is not how it is done. I eventually (1/2 hr) before boarding was able to get a seat. The rest of the flight experience was unremarkable.
