Everything was great. The only issue is unfixable. Seats are too small. 😁🤪

Everything was great. The only issue is unfixable. Seats are too small. 😁🤪

This wasn't my experience with Delta. It was just the Pegasus flight. Seats were very hard. Staff was kinda rough. Not very nice. Charged me for snacks. For a 4 hour flight I would've expected more.

Crew was nice, meal was good. Entertainment had to be rebooted 3 times and still did not work. Turns out there was residue on screen, it needed to be cleaned to prevent the touchscreen buttons from continuously activating. I had entertainment for the last 45 minutes of a 5 hour 45 minute flight. Really unacceptable for first class. Flight attendent indicated your cleaning solution creates this problem. Seems as if this is widely known, you should be using a different product or cleaning better. Really really disappointing which simply added to the wi fi on your planes with reliably never ever works.

The baggage belt was not updated on the Delta App and was displayed on the wrong belt board. Was not expecting this to happen.

The plan was delayed and left DC 90 minutes late. However, it showed a 20 minute delay on the delta app, then a 12 min delay. It turned out to be an hour delay. I found out where the plane was with flightaware. Stop keeping customers in the dark about what is going on.

Everything went smoothly, although the usual gripes about airline travel were still present: the boarding process is inefficient, the snack selection is limited, and so on. Since there was extra space on the flight, the gate agent rearranged many people's seats to put people on the aisles and windows, leaving the middle seats empty, as much as possible, which was pretty great.

Landed without a gate ready. Plane is extremely old and dirty.

All the amenities was wonderful, if they could keep their prices that low. I'd fly with them all the time.

Very old plane with no inflight entertainment. I purchased the internet pass and it was nearly unusable.

My tray was broken so i had no place to work or eat except my lap. Flight attendant said I would get an email with some credit or miles, it was a complete waste of time as I could only function at about 20% of normal. I have not received anything yet.

Comfort. Not good very little space after the person in front of you lay back.

On a more than 8 hours flight was only one meal included, which I have never experienced before. Always two meals on the overseas flight. It was very weird.

Great if not for the boarding by bus at Heathrow terminal 3. Medieval disappointing time-consuming and very hard on handicapped flyers. It was awful

Business seating is soooo uncomfortable. You can sit straight up or lay down. You need pillows behind you because the back doesn’t lay down. Those are need to “prop” you up. The chair has no padding whatsoever. Food was gross. I’ve eaten on Finnair before and the food was exceptional. This time it gave 2 people in our party diarrhea. It was the chicken dish. I took 2 bites and didn’t eat anything more. The flight attendants were nice. You needed an additional lounge in Terminal D at DFW Airport. After waiting 40 minutes to enter, we finally gave up and went to a bar across from the club doors. I’m unsure if I’ll ever book a Finnair flight again.

Very good seat, very comfortable, good food, and good service.

It was a good flight, very comfortable seats for sleeping in business class. Probably the most comfortable business class seat I've ever had (20+ times in business class on various airlines). Service was good, but the only downside is my screen didn't work and it had to be reset multiple times to get it to shut off. I had to block my eyes because the screen was white almost the entire flight and I wore an eye mask when I slept. But when eating and reading in my seat, my eyes hurt because the only way to turn the screen off was reset it and the screen would only be off for a few minutes at a time.

Everything was wonderful! AirBus seats are more comfortable to sleep in as compared to the Boeing planes.

All reviews good because...flight from BWI to London ,economy seats was miserable. I usually book 1,step up from economy but this would have added 1500 bucks 1 way. Bit the bullet and upgraded for retun flight, otherwise all ratings would have been rock bottom.

Great. It was awesome to have boarding from the front and back of the plane as it made the process go very quickly

Wish that everyone would board the back of the plane first. Also let kids on first. The gate wasn’t open at arrival and we waited 45 minutes to takeoff. They made up for time in the air.

The crew was great. Very friendly and responsive. The plane was old, small and tight. We ran out of overhead space and I had to check. Middle seat was particularly tight.

Flight itself excellent, but delayed so missed connection & got to destination 2 hrs later

The flight crew on this leg of my trip was very friendly and pleasant. Every one of them was humorous, as well as helpful and accommodating. This group was BY FAR the best crew I’ve flown with. They deserve kudos.

boarded early to only find out that flight would sit at gate for 45 min to an hour. Landed in chicago and sat on runway for over an hour before got to gate. Total delay was extensive for a 45 min flight door to door.

The flight was delayed from take off because only one runway was operational in San Francisco.

Several missed and almost missed connections. It felt like everything was being patched together last minute without enough resources and it ended up being an extremely stressful experience that basically ruined our weekend on the west coast. What a waste.

Really hard landing... as in slammed into the runway then hit the brakes really hard ...

The flight was significantly delayed. The inbound flight from EWR was delayed departing because of mechanical problems. My original departure from CLT was 5:28 pm but due to the delay of the inbound flight, after arrival, deplaning, cleaning, boarding, we did not push back from the gate until 9:00 pm. Once in the air, the flight was smooth and what was originally supposed to be an arrival in ORD at 7:30 pm local time turned out to be 9:35 pm.

Putting people that close to the bathroom, where you have to look into the bathroom as people are exiting and entering was not great and the smell was also not great. I know the airlines are desperate for more chairs, but that seat is a crime.

My bags were misplaced!!! Im in a foreign country with no bags

The staff was nice. I appreciated that I was able to take an earlier flight, even though it was last minute. The boarding process felt rather chaotic.

Overall a good experience, however Wifi was not working on the flight.

For a 4 1/2 hour international flight all we got was 1 small pack of cookies and a drink. You had to watch movies on your own devise.

Airlines should be prohibited from using the seats they get away with.

My flight got delayed a total of five times. And the boarding gate changed four times. most of the time the platform was not up-to-date with the changes taking place. The most discouraging part of the entire trip by far.

Flight left early and arrived 30 MINUTES early at the destination. Smooth trip.

American delayed the flight for a crew rest period. The delay occurred late in the evening - the earliest i can find is 10:20 pm. With a 6 am flight anyone on the flight would have already have been asleep (unless you are insane, a vampire or on drugs) and at least for me i was already on the way to the airport at 445 am the next morning when i discovered they delayed the flight until 9 am. Given the incoming flight was in the air at 6 pm the evening before this should have been figured out a lot more timely that was there only crew to use. Just frustrating given there is no consideration for customer experience anymore in flying.

Returned home with a blood clot from flight homes and the uncomfortable aircraft I was on.

Original flight was on time, then late, then changed gates...4 times. Once our newest plane came in, it was fine.

The crew was very kind, but no in-flight entertainment monitors and a 2 hour and 30 minute delay was extremely frustrating.

Was never allowed on and not refunded the full amount of the ticket plus charged a $300 processing fee.

Terrible. Lost our luggage for 4 days. Did not advise passengers there was a strike in Barcelona Airport and had zero personnel on hand at airport to advise passengers on where to go to file claims. We had to fend for ourselves. No assistance at all other than an online claims submission process that we had to find out about on our own.

Lufthansa cancelled our flight from Los Angeles to Naples Italy on March 10 for scheduled flight on March 12 Very stressful experience trying to arrange alternatives. Will never fly again with Lufthansa

Everything could have been better. What needed to be wrong with United went wrong

The staff was bit rude when I asked for an extra drink after one beer, asked for one wine glass.

Boarding was by group and we had to take the bus. There were no elevators so had to walk down the stairs. It would help to have escalators or elevators. Note I had a special needs child and the gate crew was rushing us in. The bus was full but we were packed with no seats to sit.

The food from Delhi to Frankfurt went bad or something cause I got sick after I ate the meal and felt ill the rest of my travel back to NY

Everything was on time, even though the layover in Frankfurt was 22hrs

Very friendly, service oriented and responsive crew. Very pleased with th service!

The entertainment is pretty boring. There are no new movies or TV shows from February. The food is just ok on the Atlanta to Frankfurt leg, but better on the Fra to Bengaluru leg.
