"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!"

Good in general, but i think the chair is not comfortable for traveling more than 2 hours ..

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

Horrible communication, flight boarded then we sat on plane for almost 5 hours as the runway was barely covered in snow with no plows in sight and the as we tried to taxi there was a major equipment failure due to poor push off technique causing all passengers to be taken off the flight to ultimately have the flight cancelled. There was barely any communication to passengers as to what was happening or what to do next to get placed on another flight. Arriving to my final destination a whole day later having to take a connecting flight through Lisbon to ultimately end up in New York instead of a direct flight as none available for the next day. Never flying LOT airlines again!

The seats are very narrow. Communication regarding bids for better seating could be better

Although I was flying in business class, the feeling, comfort and in general the whole experience was like flying in a low cost airline. Boarding by. Us, no priority to business class passengers. The plane was very old and looked poor and rely old. Seats do not recline. Space between rows very small. No separation between business class and economy. No separate toilet for business class passengers. Of course no entertainment, no WiFi and no charging. Very bad experience

Smooth flight, excellent crew and good food. Not enough space; sitting are too small.

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.

The flight itself was pleasant and on time. Crew was very good. However, breakfast food was barely acceptable. Unfortunately this satisfies the recent industry standards. I asked for a sandwich with ham (another choice was cheese), but received a sandwich with roast beef.

During the flight, the fleas biting me in the plane.

Very hot cabin made long flight uncomfortable, even in business class! Food was great. Istanbul business lounge had great food but too few bathrooms and seating . They also need more electric outlets for charging devices. Appreciate the ability to go through fast track lines w business class

The crew on this flight provided exceptional business class service to me.

The staff at the boarding or the rudest uninformative and no English whatsoever they’re very rude as if they are envious of you travelling I don’t understand how could someone would be this rude and this out of touch and cold

You charged me for luggage although the airline does not- you charged me for seat when customers can pick their own seat at checkout in I travel to Europe slot and I will not use kayak again

Requested food options were always finished. Supplied food items were good but of course not the desired choices.

The airport staff never announced that boarding has started. Both at iad or Islamabad or Istanbul.

Very bad experience with turkish airline tk 0001. Very uncomfortable seats and food ran out and crew was not helpful

The airline could improve its business class seats and privacy in line with its competitors.

To be prepared for being treated with disrespect by the ground crew.

Seats too much and for the price we paid eve thought economy we still had to pay $169 to check a ba that’s ridiculous and also my daughter needed water so she can take her medicine we push the boton for the attendant to get us water they never came we push it 3 times no one came and ask what we needed . Am not happy with the service at all I will not fly with TK anymore

We were in premium economy seats that appeared to be locked in plae, No reclining. My aching back.

I don’t understand how they charge as much as they do for such a poor experience

I wish the plane had pod seating for business class. I had a window seat (8K) and I had to climb over the person sitting on the aisle when I needed to get up. Also there is no partition between the seats for privacy when sleeping. The Asian airlines have much nicer business class seating. Their seats are wider for better comfort when sleeping.

The seat space seemed small especially when the person ahead reclined but other than that, very good.

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

Food was poor quality and the screens for entertainment didn’t work properly

It was a short flight, everything was good with it.

I darted through the Frankfurt airport to make my connecting flight. I asked if it was a possibility to upgrade and the agent did. This was the kindest gesture and it made up for the previous delayed flight and distress/anxiety of anticipating that Zi was going to miss my Frankfurt-Chicago connection. I cannot express my gratitude for the upgrade.. I am 5feet 10 inches do the leg space was amazing.

I meant this flight was not good, the one from Tirana to Frankfurt was better!

I was very grateful for Lufthansa's role in organizing mobility support. The touchscreen on my seat was faulty: slow, stained (I couldn't get it clean), and glitchy. This made selecting movies extremely time consuming, and twice I had to start all over from the beginning.

My touch screen at my seat wasn't working, the films BA advertised on the website for this flight were not available, and the plane was a little dated, food was good and the staff were good, just let down by the aircraft facilities.

Did not like the seating configuration at all with 2+3+2 in business class. Lacking total privacy and comfort

The flight crew was kind, flexible, and accommodating. The seats on the plane were extremely uncomfortable.

Check-in experience, for business call please provide a premium experience

Lost my luggage, ran out of food choices in business class, ground crew was completely unapologetic.

Excellent. The crew and flight were great. Checking in was easy and everyone was very helpful.

Entertainment devices on A380 need to be fixed, the seats might do with updates.

Everything. Employees offered to help me because I had to use a cane.

Check-in and boarding were great. On flight staff were rude and disrespectful. Paid for extra room and found it incredibly cramped. Bathrooms kept in poor condition. Overall negative experience.

Great seat in premium economy, great food and drinks throughout lots of in flight entertainment. 1 hour 40 min delayed flying out , 2 1/2 hour wait at passport control in tampa
