We flew business class and it was impressive. So comfortable with delicious food and very attentive and polite staff. Will definitely fly Turkish airlines again.

To get to jet blue at JFK from any connecting flight you have to go through security again.

Amazing! One of the best kept secrets in air travel!

It was crowded… the bathrooms dirty and smelly. The seats have been made even smaller.

Good overall. Seat spacing a bit tight between IST and ISB.

Excellent staff despite some trying passenger situations. Very impressed with their good attitudes and kindness.

Service was slow and checked bag was off last evening when flying business

Ordered Vegan meal - it was ok, but not exceptional. Seat ok row 39 middle section aisle. Nearly full flight - crew was busy but they did the best they could. There was a USB A port at the seat. I listened to my own music and only looked at flight information. One nice thing was the connection information was made available in the screen.

One of the worst check in process at the DIA as well as the boarding counter Changed seat at the last minute and assigned middle seat while I paid for window seat. Requested many times but to no avail . horrible customer service and very poor process Requesting refund for seat that was changed last minute

Pretty standard for long haul international flying. Food was fine, tv/movie selection was great, wifi did not work at all, crew was pleasant enough.

Flight was delayed “due to earlier delays of that plane”, so we were nearly three hours late.

I needed internet for critical matters and it never worked.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

The entertainment they offer could use some games, and maybe they could add some cookies to the snack menu. And the automated messages are a bit repetitive. But it was comfortable temperature wise and the seats were comfortable. The crew is very polite and helpful

This planes staff was top tier. Everything went great and had a great flight home.

Destroyed my suitcase. Tired of talking about it. Cancelling my unite mileage plus account.

New plane was lovely. Crew customer service is always lax but expected. Kraft on time and arrived safely.

It was a short flight so I was expecting too much

Had a one hour delay due to mechanical issue. I didn’t think I’d be able to make my connecting flight, but they waited for me and greeted me when I arrived to help things run smooth.

O’hsre taxi and deboarding took 40 minutes. Needed 20 minutes extra time between connecting flights to avoid running through terminal.

Damage May baggage and I report the airport agant and they see it

Crew was very friendly. Need lay flat beds! More snacks

Good. Rxception is the Entertainment - movies and TV shows all out of date…

I liked the crew but not the uncomfortable seats and lack of movie and tv selection.

They cancelled our connecting flight resulting in another layover reaching our final destination 8 hours later than scheduled.

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

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.

Second time with Saga Premium, everything was fab, but the entertainment centre on both my flights didn't work, plus the seat on the NY to Rek flight (Airbus) was so solid and so uncomfortable. The 737Max flight's seat was much, much better.

The staff was kind and helpful. There was no food, and you needed to bring your own earphones to use the entertainment, which I didn’t know.

Problems checking in both on the laptop and on the app. No free seating available at check-in as advertised - must pay for EVERY seat between $23 and $75. No way to cancel seat choice. App menus and site menus are not responsive, and some items are impossible to find. Crew and mobile assistance are friendly and helpful.

Very, very tight legroom. They must’ve jammed in an additional few rows of seat seating. Denver to Munich was the least legroom I’ve ever had on any flight, let alone a multi hour international journey. I will not take that flight again.

Very good, i got two seats for myself, and was comfortable with the blanket i got

Food is too little (in volume) and too spicy.. There are no snacks in the back of the plane in between meals.

We had a 1 1/2 hour delay before we left Denver. When we arrive to Frankfort, they didn’t announce that people with connecting flights to exit the plane first. My next flight was already boarding when we we taxiing in to the gate. I waited another 10 minutes to get off the plane. I had to run to catch my next flight. I mean run! I made it with one minute to spare, but my luggage did not. My luggage came two hours later on a different flight.

Both flights were delayed and we missed our connection. Our second flight was delayed 3 times. I have always had great service and never any problems with my flights on Lufthansa. My last two flights were, unfortunately, awful. I fly quite often to Germany and have had better luck with United than Lufthansa.

Excellent staff and flight experience. Would rather that I had upgraded to Premium Economy for extra space, but I will know to do it next time.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

Sorry, I’m not a fan of United. The seats are just too cramped and uncomfortable if you are traveling very far.

Zero legroom or space in economy. Flight was delayed into Munich causing a missed connecting flight and other missed bookings. :(

A major problem at the Frankfurt terminal. You see your connecting flight is on concourse A and you see signs for A, but when you start to walk out to A, only then do you find A is in another terminal which requires a bus ride, passport control and customs. If you sit around in the first terminal too long, you can miss your flight. We made ours.

Work being done at DIA made it difficult to find BA desk.

I’ve never been on a trans-Atlantic (or Pacific) flight where the seats don’t recline—not even a little. I asked my seat mate when BA starting doing this and he said “Oh, a few years ago.” I couldn’t sleep, with my head falling forward waking me continuously, and came off the plane incredibly stiff. I booked a Premium Economy seat to get a more comfortable seat, which was worse than most basic Economy seats I’ve ever booked.

The gate agent made me check my carry-on in Denver, even though I've traveled all over taking this case on the plane. Beware folks. Food in Premium Economy was quite good - excellent blanket! Flight attendants on the Heathrow-to-Budapest flight on 3-27-2026 were quite snappy. I got a frown when asked to unscrew the water bottle cap for me (I had a cast on my right arm). Also woke up right when they were handing out biscuits. She had given my rowmates one and was in the process of giving water when I asked for a biscuit. She scolded me and said, "You snooze, you lose". She did give me one, but I thought that comment was uncalled for.

Seating and food was the worst we have experienced in 35 years of traveling for both personal and busines .

Everything was very good! I personally struggled with the heat in the cabin for the first 2 hours

Flight was delayed. Though I checked in with BA live chat three times, our special meals were not provided.

Was 3 hrs delayed and my poor friend I met in Barcelona was waiting at airport for 3 hrs. Dallas airport was awful

Late in leaving the US. Late in arriving in UK. 2 plua hous on ground in UK before leaving. Late in arriving in Spain. Didn't get our bags until the next night.

Comfortable, pleasant staff, quiet, good entertainment, food, drinks. Better than American (flight back) when we were crammed in and staff sometimes indifferent.

The perfect jet stream back saved over 1 hour in the air.
