Food has been disappointing in both legs of flight to india

Great staff great experience, made a 2 hour delay very bearable

Great staff, great experience, made a 2 hour delay very bearable

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Great crew - old style upper class seats on the older fleet now feels dated

Premium economy more comfortable than economy, but not by much. Did was awful, do not try the omelette. Flight crew were helpful. Flight was delayed by over an hour. Overall but bad, arrived safely and thank God.

Both flights delayed. 2nd flight over 3 hours late mechanical issues

Flight was delayed 45 minutes because originating flight was coming from Newark. No complimentary snacks were offered on this 5+ hour flight. No screens for the flight, but movies offered if you had already downloaded the United app (which I hadn't on my ipad). No USB ports, only a flimsy plug-in port near the bottom of the seat that was hard to see and kept coming unplugged.

It was good but only meal served is very less. Meantime good to add rice and chicken in one of meal

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

On the way my flight entertainment wouldn’t work the screen went black and no matter how many times I tried to turn it on it wouldn’t. Food was surprisingly good but the tray tables were tiny so you couldn’t get anything else on the table. The seats hardly go back and are not overly comfortable. Wouldn’t fly United again.

Unbelievably poor service from flight attendants. They didn’t even do water service on a four hour flight. Just disrespectful.

Flight was late - I was downgraded from first class to coach

Movie selection is good. Crew did not understand mileage program and were no help. Sick later. Food?

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

The flight attendants were very rude, beyond comprehension. I took a business class from London to SFO for the first time on United. When I asked for a second piece of bread during dinner, the serving attendant threw a 3rd bread on my plate and said, “here. You can have this one too”! I couldn’t believe the rudeness of the attendant. Most all attendants were very rude, unhelpful, sing the food was absolutely disgusting. Never fly United internationally in business class. My flight back to SFO was a nightmare!!

Boarding, crew, food and baggage handling excellent (no bags lost, yay!). However for an 8 hour flight, there were limited entertainment options. And really would have liked to have a pillow!

The crew was super friendly and helpful. The food was quite good. An overall positive experience.

Plane delayed due to weather. Plane boarded, then told to unboard due to a maintenance issue.

A more organized boarding experience and better food would have made the experience better.

Was all good.l including a sofdrink. AA improved significantly. There was no entertainment.

why can't planes be boarded from back to front?? everything was great otherwise

We flew into Barcelona and the plane was so cramped and very uncomfortable and dirty. But we flew out of Madrid and that plane was much better. Would fly Iberia again.

For what we are willing to pay for international air travel, our experience was very good. We had no problem checking in, we had very little wait time at the AA counter in Madrid, and the staff in Madrid were very helpful. The flight crew was helpful and courteous, the plane was on the newer side, and our assigned seats were together without us needing to purchase them. The flight took off on time and arrived early. Overall, it was a pleasant experience or as much as could be expected in economy for almost 10 hours.

Boarding was easy, the flight left on time and even landed 20 minutes early. The food was plentiful and really good! The crew was kind & helpful. Overall it was an exceptional experience!

We were delayed 2 hours because the crew was late. They need better planning by the crew, we had to sit in uncomfortable seats waiting for them.

Some of the crew was sassy and not super helpful. The food was okay, but it seems like they were all unprepared compared to my flight I did from JFK to Frankfurt

We missed our flight. There was not enough time built into the layover to get through immigration, customs, bagclaim, bag rechecking, and the long trip to another terminal and gate. Kayak really screwed up. We took the bus up to Wisconsin and then were picked up in Brookfield by private car. It was lucky we didnt miss the last bus out.

We were in premium economy seats that appeared to be locked in plae, No reclining. My aching back.

I don’t understand how they charge as much as they do for such a poor experience

Lufthansa flight LH04414 from Munich to Washington DC, was fine. Efficient and safe!

I wish the plane had pod seating for business class. I had a window seat (8K) and I had to climb over the person sitting on the aisle when I needed to get up. Also there is no partition between the seats for privacy when sleeping. The Asian airlines have much nicer business class seating. Their seats are wider for better comfort when sleeping.

Bumpy ride, not Lufthansa‘s fault. Crew managed a situation over a back rest to far down well. It was two iles behind me. The person putting the seat down, against the other person’s knees, was quite rude and belligerent and needed to be told in a no nonsense matter to stopp. Male flight attendant did good job.

Patrick and the whole crew were amazing! Hope to have this team for all my European trips.

This review is based on 2 things: 1. The lack of hygiene on the plane. 2. William - the head flight attendant. The lack of cleanliness on the plane upon arrival was appalling. Being given a sanitizing wipe upon boarding of the plane is shocking when you consider the cost of a business class flight. UA expects me to do their job and clean all the bread, food and debris left from previous guests. Does this sound normal to you. The seat, the food table and the sides were full of crumbs, chocolate and dirt. When I told the flight attendant they just gave me more wipes so I could clean it myself. Secondly, William the business cabin head flight attendant was so busy flirting with a couple in the front that his attention to the other guests was minimal. He continuously asked them if they were ok or if they needed anything and it didn’t matter if the rest of us needed anything. And if you are the lead attendant shouldn’t you be checking if the bathrooms in business class are clean and needing toilet paper. There were 2 bathrooms in business. Halfway through the flight the first bathroom was closed and the second bathroom was dirty and had no toilet paper one hour and a half before the flight landed. He needs additional training on prioritizing things. He should care less about flirting and more about his work

Booked seats (paid extra) online and found they didn’t exist on the flight. We were then separated from the rest of our party. Given seats in the very back of the plane. We will not fly Discover or Lufthansa again. We will not book flights or travel through Kayak again!

Check-in experience, for business call please provide a premium experience

Lost my luggage, ran out of food choices in business class, ground crew was completely unapologetic.

Excellent. The crew and flight were great. Checking in was easy and everyone was very helpful.

Entertainment devices on A380 need to be fixed, the seats might do with updates.

Everything. Employees offered to help me because I had to use a cane.

Check-in and boarding were great. On flight staff were rude and disrespectful. Paid for extra room and found it incredibly cramped. Bathrooms kept in poor condition. Overall negative experience.

Great seat in premium economy, great food and drinks throughout lots of in flight entertainment. 1 hour 40 min delayed flying out , 2 1/2 hour wait at passport control in tampa

My seat cushion was poor. The cushion was compressed and was uncomfortable for such a long flight.

I was in a bulkhead seat and my tray table wasn't level. Eating was difficult.

Audi visual not working for a whole group of seats in first class. How does a plane leave the main hub in such poor condition? How much that we can’t see so immediately is also compromised?
