Seating and zone. The minor I went with didn’t even seat close to me

Seating and zone. The minor I went with didn’t even seat close to me

My seat 3G did not go down fully and the buttons were not working properly

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

Our flight was canceled same day and we were never informed. Had to pay more and worse seating on another airline.

Did not like that we couldn't complete check in on-line without providing pictures of our passports. Worry about identity theft. We had no delays and boarding was handled In an efficient manner.

Excellent! I got to Munich and was transferred to my Lufthansa flight quickly, in 15 to 20 minutes, so I did not miss my flight. However, I had checked my overhead bag at the boarding gate in Tampa. That got to Tunis the next day. That is to be expected.

WiFi didn’t exist , seats were super cramped, lights stayed on near my seat for a long time while others were dimmed, the food/trash/drink cart hit my shoulder at least a couple of times while moving, food options were down to just one option by the time it got to my row, the utensils were garbage (knife bent at a couple of places by the time I was done eating) the spoon was very flimsy plastic

Cree was organized and pleasant. Plane had good seating but as it’s a shuttle toilets hadn’t been thoroughly cleaned (eg. bins too full)

Vegetarian selection could be better. Bread was too hard to chew.

Crew was friendly and competent. Food, wine, and entertainment were excellent except the raw tuna on the flight to Split. Recommend against serving that - at least as the only option. Many medical conditions do not allow people to eat raw fish.

United didn’t even try to hold the flight for me. They knew I had a tight connection and when I arrived at the gate less than 10 mins after final boarding the flight had already gone. The gate agent wasn’t even notified that I was on my way. She was told I wasn’t at the airport

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

The flight was delayed so we were dead tired, and after that the turbulence was horrible. I was very scared.

It's a long flight and that is always difficult. I was comfortable and well. The movies available were great and the crew was good.

Premium Economy Good crew, good service, excellent food. Seat back screen just not bright enough.

Flight was delayed an no one cares, or try to help passengers to get the conexión.

Our flight was cancelled while we are on our way to the airport. So, no notice. We were rescheduled to another airline with a 2 hour later takeoff and so arrived at our destination on time. We pre-paid American Airlines $190 to upgrade our seats. No refund. So no use for AA or Kayak.

Terrible, horrible, disappointing- without telling us they changed planes and moved and separated our seats to opposite sides - said they changed seats putting us together - got to airport to find no, they did not - we sat opposing sides of plane - food overly salty to inedible, never saw stewardess but once - it was terrible

I had pre-selected a meal. I was told that it cannot be served because of some issue with the vendor. When travelling business class, I expect better service

The business class layout of chairs was weired. You are sitting directly across stranger.,

We did not have enough time to make our connecting flight. As a result, we were put onto a different airline for our second leg. The different airline was NOT comparable to British Airlines, and our arrival was significantly delayed. The actual flight on BA was amazing.

Human interaction. Thought there would be more service-even a smile would have been nice.

Tv screens and movie selection v good. Friendly staff. They were really worried about max capacity and room for carryons. That is never fun but i had no problem finding space when I boarded.

Awful. The Iceland airport was a complete mess. Boarding was a chaotic, the seats were awful, there was a group of rowdy 20 something men in our row hooting and hollering, ordering alcoholic drink after drink. Yelling and laughing at the top of their lungs and the crew just went along with it. Passengers complained to the men, asking if they could keep it down (it was a night time flight so people wanted to sleep). They never listened crew continued to laugh with them, flirt with them and serve them more drinks. No free food or snacks, seats were horribly uncomfortable. Worst flight I've had in a long time

On-time arrivals and departures. Crew helpful and friendly. Yet everything costs extra: seat selection, food, even airphones!

Pleasant, attentive flight attendants, but they’ve got to upgrade their seats to be a true “business class” carrier.

Friendly flight crew. Airplane (757) configured as a domestic flight (no lie-flat seats) & no advanced meal selection.

Was a bit surprised that Icelandair flies a domestically configured 757s on long-haul flights to Iceland (no lie-flat seats in business class).

The Icelandair crew was so kind!!! Thank you for making my first trip to Paris a great one!

I am not going to fillo this out for each leg of my trip. My first review holds for the experience

The movie choices were poor. The worst problem is the treatment of passengers durinng pre-boarding. In one case the primes were checked in and sent down the boarding tunnek only to stand waiting there while the plane is cleaned. In the second case the bus was loaded, the doors closed and just stood there unmoving like sardeines in a tin for over TEN minutes. In both cases it was rough on us old guys who find standing for long periods trying.. In other words, Donnt just stack us up and forget us.

I had no idea that my ticket only paid for my right to get on the plane. They charged me $130 for my carry-on bag because it was 1 inch too big she claimed but it wasn’t! Then they wanted another fee for everything. I had no idea that Icelandair had changed to such a bargain basement airline. I was very disappointed.

Screen didn't work, and neither did the button to tilt the seat even though the seat was comfortable

I liked the air hostesses, but no wifi was available for flight. my original flight was canceled and rebooking was difficult and no reason was given for cancellation. Business class cabin was nice and spacious.

I like American Airlines and their safety record. They provide quality service and a feel safe enough to prefer American Airlines over other carriers even if I have to pay a little more.

Overall ok. Best part has always been the sundae dessert.

Flight was delayed by over two hours and that meant my connecting flight was in jeopardy but there was no acknowledgement or help from the BA staff

Business class on British Air with the Airbus 320 means the same seating as main cabin ( 3 - 3), but with the middle seat of each three-seat row blocked off to become a platform/table. This is decidedly NOT a business class experience. Other aspects of the flight were fine.

Wish the food and overall service was better. They treat Business class passengers same as economy

British Airways offers amenities subpar with all other airlines flying internationally. Sharing tis based on my experience with flying at least five other airline between IAD-DEL in the last six months.

Worth every penny to upgrade to BC. Treated and felt more like First Class

I missed my flight because I was sick and the medicine the chemist provided made me sleepy. I had to pay $3500 to get home because you classified me as a no-show and would not listen to me otherwise. In addition you wanted to route me through Dubai, which was under siege by the time I arrived home and would’ve been in trouble. Had I taken that route

The internet was working on both sectors of the flight so hard to take the flight if you are on business.
