"If you're flying from Istanbul to Chicago, here are some tips to keep in mind: 1. *Choose a comfortable airline*: I recommend flying with Turkish Airlines or United Airlines, as they offer a relatively smooth and efficient boarding process. 2. *Be prepared for long flight*: The flight from Istanbul to Chicago can take around 10-11 hours, so make sure to bring entertainment, snacks, and comfortable clothing. 3. *Take advantage of in-flight amenities*: Both Turkish Airlines and United Airlines offer a range of in-flight amenities, including meals, drinks, and entertainment. 4. *Plan for jet lag*: Chicago is 8 hours behind Istanbul, so plan accordingly and try to adjust your sleep schedule before arrival. As for the boarding process, I found Turkish Airlines to be particularly comfortable and efficient. They offer: - *Priority boarding*: For passengers with special needs or priority status. - *Efficient queue management*: Turkish Airlines uses a well-organized queue system to minimize waiting times. - *Friendly staff*: The flight attendants and ground staff are always helpful and welcoming. Overall, with some planning and preparation, you can have a comfortable and enjoyable flight from Istanbul to Chicago!"

My ONLY complaint with LOT was the lack of WiFi and the food in business class… still, I use them because they have great connections to Chicago and they fly the 787 - which I think is a great wide body jet. Well… now LOT has WiFi (good satellite speeds) and AMAZING food. LOT now is giving Turkish Airlines a big big run for the money. And they consistently have less expensive business class. I am a very happy customer!

Issue with boarding, group of passengers on a religious trip coming back to NYC kept trying to change seats, even standing when the plane was pushing back. Crew/Pilot kept very good composure, some passengers got aggravated and started venting out loud but this group created a serious security risk. Crew/Pilot should've been more stringent and called in security or remove them from the flight.

The seat was paid for but given for some different person .

Krakow airport is very disorganized. nice seats. friendly crew. long legs had screens. short leg did not

Flight was delayed for a hour from Warsaw, not sure why. When we landed in Chicago, plane was still on the runway for about half a hour. Took a while to get off.

No WiFi and ok comfort in business class. Home safe I guess that’s all that really matters.

LOT was very disorganized at Istanbul airport with no communication with travelers. Our flight was delayed over and hour and a half and there were no announcements, displays or anything about it. It almost left me missing my second flight!

I would like to be able to choose the seat before the flight without paying extra money. Family members should not to be separated from each other.

Flight was delayed by a hour could have been better addressed. Flight was fine with great service by the flight attendants

All good. Didn’t get the seats I booked online. Luckily, copassanger cooperated! Mistake- I failed to verify connecting flight seats details at Mumbai. Staff at Mumbai airport to be blamed equally!

Horrible service at the baggage claim. Stuck on plane for an hour due to taxing and no gate.

I really would like it if they provided at least some limited free wi-fi.

Food is very turkish. No regard for other natinalities taste and preference. The entertainment can be improved- it was the same menu on 10/8/25 and 10/25/25. The boarding is the worst in the airline industry- I suggest you ask your staff to and watch how other airlines do it.

We couldn’t fly to Chicago on our booked flight. The flight was overbooked.

Took forever to board. They made announcements without the loudspeaker and since the waiting room was full of screaming kids, no one could hear what they were saying. The business class sleeper seats were designed for tall skinny people. When partially reclined there was nowhere to rest my feet because they did not reach the footrest. and when fully reclined there wasn't room at my sides for my arms. Definitely one of the worst sleeper seats I have ever had.

About an hour delay but we made it to Chicago. I feel that the smaller connecting flights are the ones that cause the delays on the bigger planes that fly international.

One of the best flights I have been on in a while.

Here's a sample answer: "Honestly, I was really impressed with Turkish Airlines, but if I had to suggest one area for improvement, it would be: - *More efficient boarding process*: I noticed that boarding took a bit longer than expected, which might be frustrating for passengers with tight connections.

Not worth pay business class and get service economy class

Great airline with excellent service! Only drawback was the meat served was overcooked on both flights.

The flight crew were very helpful. The seats were very close together. There was barely room to sit without touching the person next to you.

I’m an EP on AA every year for more than a decade but this was a very pleasant and surprising experience. Clean and sizable plane for HOU to CHI. 5 row first class. And excellent food in first class the steak option was really good. Your flight attendants even better. Seat 5A

Gluten free snack options and meals that offer both gluten free and dairy free.

Not a bad flight but a long delay boarding and taking off due to the pilot not arriving on time.

I would have preferred a flight voucher and to hop on a different flight. Delayed over 6 hours.

I almost missed my connection in Chicago due to having to wait on a gate to be open I am assuming. Having to run from E terminal to C terminal and I barely made it there before they closed the door. This may not be the actual airline's fault it's crazy how there is so little time between flight especially when they are placed so far apart in the airport.

The Wi-Fi did not work, so you weren't able to watch entertainment on your own device. They did not have wired headphones so you couldn't watch it on the in-seat entertainment screen either. There was plenty of time to do a drink and snag service but the flight attendants chose not to.

Great experience, boarding was fast and efficient, so much so that we arrived to Chicago very early

They cancelled my flight and rebooked for Monday from Saturday without my consent. Putting me in a stressful spot. I have important medical appointments that I can’t miss and work. I tried to contact them to either rebook or request a refund, but I was always 200 or more in line and could never get ahold of customer service the call would always hang up after waiting 2 hours on hold. I’m not sure if I will ever get a refund even though I paid for seats as well, but my only option was to spend more money to rebook with another airline.

Crew was wonderful and attentive. Chris (I think that was his name as I was seated in the back in 52F) was amazing and funny. The captain was informative and did everything to get us to Denver as close to on time as possible. Bags came quickly at baggage claim. Online check in would not allow me to change my seat 24 hours ahead of time with dozens of seats showing open and I really do not enjoy being in the back of the plane for long international flights.

Very comfortable plane. The food was very good (for airplane food). The crew was great

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

Perfect airline, super friendly, great service, tasty food. Would fly again.

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

It was good. The seats in economy weren’t bad

Food is delicious I’ve tried Thai green chicken curry and it was perfect!

Flight was very late, meaning a missed connection in Frankfurt, and staff completely unhelpful or just absent. Handicap accommodations, reserved in advance, somehow never made it through the system for the second trip in a row!

During the boarding process women with small children were not invited to board first and were clumped into general crowd boarding, also during the 3 hr flight there was no food or water offered and I was traveling with a small child who needed water. I would appreciated that next time Luftansa informs that on 3 hr flight there would be no food or water offered so that I can prepare for the flight. In addition, traveling to the plane with the bus and then climbing up the stairs into the aircraft with small child and overhead luggage was probably the worst experience that I had in years traveling. Overall, will try to avoid traveling with Luftansa by all means. Thank you

Someones phone kept ringing and the flight assistant did nothing about it. Not even an announcement.

I had such a wonderful flight with Lufthansa. The crew was great and I was able to catch some much needed sleep. I look forward to using Lufthansa in the future!

Was very bad the cancel the flight after when we arrived to London

They lost my baggage and still waiting an update when I can receive it

American Airlines is the worst airline to fly. you can’t get on an earlier flight if you don’t have ‘status’, they cancel their flights with no warning, and they lie about why their flights are delayed so they don’t have to pay for meals or hotels. They lost me as a customer after this trip. I’ll be flying Delta or Untied from now on.

The checkin process is always horrendous with this airline. They never have enough people working the desk or people assisting in the lines. Rude and unbothered. I never pick British Airways- I always get swapped in via American Airlines and may need to stop using American Airlines as well. No entertainment in flight. And they seem more concerned about selling food and drinks then they are about customer comfort

Terrible service. Stewardess behavior horrible. No sense of customer service. Seats were small, in general very bad experience which is not the case for me on other international flights via BA

TIRED OLD plane. Seat cushion is completely old and NOT cushion at all; after an hour of flying butt hurts. Boarding is a complete disaster. No one respects the boarding groups, and the BA boarding crew care less about boarding groups or Tier status. What is the point of spending all this money on Business Class tickets when no one respects the boarding system? It took 90 minutes since we landed to get our luggage. 20 minutes to show on the screen which belt we are supposed to go to and another 1 hour to get our luggage - not the kind of service you will expect from BA at LHR

My ticket was cancelled unannounced and I was left stranded in the air port

We were told they needed to take some luggage off the plane and it would take 15 min. It took over an hour and no communication from the captain or crew. We were delayed about 2 hours in full.

Apart from missing my flight because of another British Airway plane parking issues and had to wait 7 hours, i'd say all was just ok

I booked 2 tickets together and they separated our seats. A few months before the flight I got a call asking if I want to pay $100 each flight to choose my seat since I won’t get the option but that wasn’t true and i’ve never done seat selection over the phone, very weird. They do offer free seat changes when you check in but there was nothing available. I assume this is because people who book directly with the airline get to choose their seats when they buy the ticket. Will not be booking through kayak next time and will book directly with the airline so we can sit together.
