We booked with ANA but got put on a United flight on the way back. ANA was so much nicer. We were really let down flying United, having booked an ANA flight. When they swapped our flight, they didn't seat us all together either. United crew should take lessons from ANA!

Issue happened with my landing. Didn't make it in time to next gate. Delta did everything they could to blame me, insulted me on The phone and definitely provided the worst customer service

They were very dishonest about everything. We need to be there in Australia on Monday morning for very important event but reached Australia Monday night 8PM. Virgin Australia contatcted out their flight from SJC to LAX through Delta and Delta cancelled flights becaue no-show of Pilot to operate the plan. What a Joke???? We asked them to put us through another carrier to LAX for connecting flight they refused.Very very BAD. It was a big miss for us.. never again Delta/Virgin Australia..............

Terrific Gate Team in Houston, who were extremely helpful with my current disability (my foot is in a walking boot). Gate agent immediately approached me once I got to the gate (via wheelchair) to see if I needed anything else. Then she took it upon herself to move my seat so that I had an empty row on the flight to prop my leg up on the flight, which was excellent customer service. She anticipated my needs & exceeded them. She signaled for me to board early, so I had enough time & space to get down the ramp. Gate agents like her are hard to find these days. I wish there were more agents like her. Flight to Indy- Plane were more spacious between the seats. My knees had 6”-8” between them & the seat in front of them. It was a new plane, so if this is the direction that United is going with their aircrafts, they will have lots of happy flyers.

It was recommended to download the United app for free inflight Enterainment once I purchased the inflight WiFi. After purchased, none of the movies or tv shows would play. It seemed like slow WiFi was making it impossible to utilize the Entertainment promoted by United.

My seat was comfortable, with good head and neck support.

BA doesn't allow guitars as carry ins, unlike most every other overseas carrier. That's a major negative for me, and I've spread the word to other musicians who will avoid the company. Terrible policy.

Leg room. Direct flight from Europe. Drink services were a lot better than our outbound flight.

Plane was incredibly old for a long haul flight, with no power socket and extremely outdated TV's. Seats were dirty and small. We were in row 34 (middle of the plane over the wing) and when they got to us with the food options, they had already run out of the second choice on both occasions. On the first service, we asked the attendant if the food had any fish/seafood ingredients (due to allergies) and she said no. We then read on the lid of the food tray that there was a possibility of fish traces so my husband could not eat it. When we told the attendant about it she told us they didn't have anything else. Hard to believe there was nothing they could do, we've never experienced this issue before. We then asked another flight attendant if there was any food available for purchase but she said no. Luckily, she was able to find a vegetarian dish that my husband could eat. We're grateful that she found this as the next food service was not until 6 hours later. Sad that we had to ask again, we were expecting that they cared a little more. Overall, BA didn't meet our expectations unfortunately. This was a trip to Europe in which we took 4 BA flights and overall, the experience was of that no better than a low cost. Would have a hard time thinking of choosing this airline again.

Uneventful, other than having missed the original connecting flight on account of delays.

There was no food or entertainment, so I can't rate them.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
