Insights shared by verified travelers who flew the route from O'Hare Intl to Europe 
JKFlew with American Airlines-Sep 2026
Ask ahead of time, if the aircraft can provide AC and/or oxygen to passengers after boarding.
MarkFlew with United Airlines-Jul 2026
Order your choice of food in advance on the website. Take snacks as supplement as onboard food is inadequate
Verified travelerFlew with United Airlines-Apr 2026
Make sure your flight has more than three hours as layover if you’re connecting to another flight.
Verified travelerFlew with British Airways-Mar 2026
Take early morning flights to adjust to weather-related delays.
ZacharyFlew with Scandinavian Airlines-Nov 2025
Buy out a row so you have room to sleep.
Verified travelerFlew with British Airways-Jun 2025
Get a wheel chair if you have difficulty walking
JoeFlew with Iberia-Apr 2025
Get there early. Nice airport options while you wait.
Verified travelerFlew with Iberia-May 2025
Get to the airport early so you’re relaxed. Con yourself into believing it’s bedtime and try to sleep so that you can keep going all day when you get there. If you can afford more comfy seats it might be worth it - though I always have the cheap ones so I can’t say for sure. Try very hard not to. sit in the middle. I’m small and the guy next to me played games all night and didn’t care that he continually ( with every move) jabbed me with his arm. This was my first flight with Cheap Flights and it was far less convenient than other times I’ve flown overseas.
TFlew with Scandinavian Airlines-Jan 2025
Don’t forget you can pinch and slide the headrest up and down for maximum sleeping comfort.
DinaFlew with United Airlines-Jan 2025
Anticipate delays, prepare for long walks through Heathrow to baggage claim or for connections.
Verified travelerFlew with SWISS-Sep 2024
Bring a neck pillow and a heavy sweater bc it does get cold. I used the blanket for my legs. Also: get a seat in the aisle.
Verified travelerFlew with United Airlines-Sep 2024
Be prepared to wait in long line for boarder control. Allow enough time for your layover
Verified travelerFlew with Austrian Airlines-Oct 2024
This Austrian 787-9 plane has very uncomfortable seats. Extremely tight space in economy class. If you can, upgrade to premium economy. Do not select seats close to the restrooms. The plane only has two restrooms center cabin and there’s always a line of people waiting to use the restrooms.
RuthFlew with United Airlines-Oct 2024
Facial recognition seemed to slow boarding down, not speed it up. Why don’t airlines board from the back to the front? That would certainly speed things up!
MikeFlew with British Airways-Jun 2024
Make sure you check the plane type and economy seating space.
FreddieFlew with Icelandair-May 2024
If you’re in business class board first to avoid queuing
EFlew with SWISS-May 2024
Difficult finding the international terminal in Chicago and have to take a long bus ride to get there, so you need lots of time. Immigration in Zurich was really slow. I had to skip to the front and still barely made my connection.
KariFlew with British Airways-May 2024
Always check to confirm your assistance is in system. No wheelchair waiting for me in London. Had no clue about airport or how to get around. Got lost easy
AaronFlew with American Airlines-Dec 2023
Find a flight where you are allowed to choose your seats before the day of boarding for anything international.

Food seats were good Flight was delayed for over an hour, missed connecting flight, lot automatically rescheduled us to a new flight which was good but lost approximately 4 hours. Not a good way to start a vacation.

Stuck on a plane for 6 hours due to a technical or mechanical issue.

Boarding was a madhouse. Airport staff was completely disinterested in communicating about the delays. Never again.

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

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

The crew and flight were amazing . However , my bag’s locker got broken and no refund provided . Everything else was amazing except this bad incident that ruined my experience

The seats are small and the movie selection was disappointing. However, the food was excellent and the cabin crew was attentive and kind.

Plane is super outdated, seats not that comfortable for business class. Lounge also out dated. They need to catch up to 2024. Don’t think I’d ever fly again.

Boeng Dreamliner has so tiny seats, so even medium and smaller size people have not enough room to fill comfortable..

All good! But sandwiches for breakfast need to be warm!!!!! Not cold!!! You do not want anything cold in your stomach in the morning!… think about it!

I always travel on Turkish Airlines but seriously I am I am considering to change because this is not the first time that the flight attendant are rude and they dont help. I asked for cold water with ice 5 times and I got water with no ice and this is not the first time to ask for something and you dont get it. Also I noticed this behavior only towards people who are not turkish.

Istanbul to Lahore flight was less than standard for international business class cabins. Seat did not were not flat and it did not operate easily. I had to push buttons hard repeatedly to operate the seat. I was in 5A seat

My, Syed Zawar Hussein Shirazi frequently flyer membership number was not included on my boarding pass from O’Hare to Istanbul despite my reminder to the attendant at check in. Further she forgot to give me my boarding pass form Istanbul to Lahore and she needs to improve her customer service, please 🙏

Chicago to Istanbul was a much better experience than I expected since I’m more accustomed to Qatar Airways business class. The business lounge in the Istanbul airport was amazing - loved the lockers and phone charging stations, and the bathroom was a spa experience in itself. The onward leg from Istanbul to Karachi was utterly disappointing. Terrible plane, and I felt like I was in economy - the seats don’t come near to lying flat and the food was mediocre. What a sad downgrade - it isn’t as though the ticket on that leg was cheaper. So, on that front, there’s no contest with Qatar airways.

Second leg of Turkish Airline with Indigo is disaster for following reason. 1) You have to carry your cabin bags through ladder to boeing 777 because it was parked somewhere in parking lot and was not given a gate to board passengers and this seems to be people traveling to and fro from those flights and is not issue with flight itself. 2) I choose non vegetarian food on Turkish portal way ahead of checkin to entire trip, However the Indigo flight gave me random veg food saying they code veg food code from Turkish. 3) Indigo did not served any alcoholic beverages stating some weird reason which is non nonsensical. 4)Indigo have TV screens in front of you but it displays nothing except "Welcome Onboard" with annoying white black ground in dark flight. This is the most stupidest and annoying part because you are held hostage for 7 hours and only thing you could do is stare back at white screen which does not have entertainment package or even flight tracker. Such a shame.

During mid flight, try to get a flight attendant to help I couldn’t find one Otherwise, everything was perfect

The 2 agents on the check in counter were super nice , helpful and very polite. Boarding was like a 1 2 3, I would recommend Turkish airlines for your next trip.

7 stars hospitality and an excellent service by the Turkish Airline entire team. Somehow, our membership numbers for mileage points were not indicated on our boarding passes issued at O’Hare Airport by the Turkish Airlines check in desk. During transit in Istanbul, I brought to attention of customer service Turkish Airlines. Please have our mileage points posted to our membership account from O’Hare Chicago to Lahore for both my wife Kaukab Shirazi Thank you

Terrible boarding process, no proper line maintained even for business class, crews are not very attentive, business class food quality / variety / quantity have gone down, everything has become cheap.

Food quality and the overall service of the staff and significantly decreased. The flight was delayed at the Istanbul airport and the passengers were kept onboard for more than 3 hours. The staff didn’t kept the passengers informed and everyone was upset.

The layovers / connections were too short and too long. I SPRINTED to make the connection from OSL-JFK and then SAT for over 6 hours from JFK-BUF. I don’t mind a longer layover more than I want to RUN to make my next connection

Flight crew was very kind and polite. They had to deal with an unnamed issue right beside me, and did so with respect.

The layover was very long. Other than that, great trip so far

Elderly traveler with disability was bumped from extra legroom to economy with little legroom. He couldn’t bend his knee to fit in the seat. Very uncomfortable for a 7 hour flight and will be reported to DOT. Then the food was disgusting. Boiled chicken with boiled rice and steamed veggies. 3 slices of carrot and one broccoli. We couldn’t eat it. No salt or pepper provided. Disgusting.

No crying babies the whole flight would be nice. Impossible to sleep. No free snacks , only the main meal

They lost my luggage and can’t find it. My trip is ruined. Online tracking of lost luggage doesn’t work

Seat was lumpier than I’ve ever remembered it to be although comfortable when tilted back. I don’t recall being that hungry after being served food from SAS before. Flight attendant on the second flight to Aalborg seemed to be having a bad day.

On this shorter leg and with an older plane, just mediocre. On the connecting long haul (Chicago to Copenhagen) everything was great.

My outbound flight was incredible... Milan to Chicago. The crew worked so well together. Each passenger felt spoiled and incredibly valued. The crew on this flight was fine. Nothing to complain specifically about but could not give top rating only because of the superior crew, hospitality, warmth we felt on the first flight. Unfortunately. You managed to lose my luggage ..my only piece checked in. Lost in Copenhagen so I had the added stress, time wasted to file the report. To make things worse, Italian rail decided to strike that Sunday so I could not take the train as planned back to Switzerland. Horrible waiting time and poor communication for boarding substitution bus. The substition bus to the town of Stabio did not run on time and was late about 40 minutes.

The flight was cancelled early on and messed up the whole vacation and hard to get a refund from Kayak as they owned the ticket and of course they did not believe that SAS cancelled the ticket. Definite bad side to third party. SAS had rescheduled but overlapped the connecting flights. That did not work. Flight was cancelled long ago but Kayak still has it. Like it was taken? Bad IT ? Or all assumptions and no follow up which is the whole IT world. It needs to wake up and be more efficient. Especially as the world is going, there will be no freedom to do anything. And we will be living like the Middle Ages. Yeah, go read up on that while you still can.

On time, easy boarding. Anytime you sit in an economy seat, it’s uncomfortable. New plane and the bathrooms were in the galley at the back of the plane which seemed odd.

Terrible service - they don’t want to be there and bad food. Entertainment system in economy from the 2000s

No drink service but there was no N/A as an option to choose. Seats were extremely tight. I am under 5.5 and I bumped my knees have no idea how taller people could manage.

Flight delayed, last seat on the plane, no arrival Gate available due to the plane departing late

Kayak booked this flight with only 1h 20min layover in Chicago. This made it impossible for me and several other passengers to reach this flight. Moreover, the gate closed boarding in spite of several passengers still on their way without waiting even one more minute. However, the plane departed with 20min (!) delay, i.e., there would have been at least 15 min time to let the delayed passengers board without causing any delays. I complained and as a "thank you" the attendent booked us on the last (!) flight to Indianapolis ~7h later! Thankfully, I caught the spitefulness and the United customer line rebooked the flight to an earlier flight. Although I can't grade this particular flight since I never had a chance to take it, Kayak made the mistake of a too short layover and the crew at the gate was awful.

Flight did not have wifi service. It was experiencing technical difficulties. Definitely and old plane that needs updating.

This flight has a history of leaving late, however, I was pleasantly surprised that it was not delayed this day. The flight went smooth, except I was in a window seat and the wall and my feet were freezing. I found it difficult to sleep due to being so cold, I also was using 2 provided UAL blankets and could not get my feet warm. This was annoying, but I still made it there on time and safe.

Old 757 with poor entertainment system. United no longer partners with United for free text and email. O'Hara an absolute disaster! Limited gates clauses two hour delay. Unfortunately this appears to be the norm.

It was a good experience, unfortunately my checked baggages were come late and not arrived on time.

Very stressful to locate United Airline boarding area, delayed flight, changing boarding area again to another location with all tiredness 😩. But flying was fine.

I was booked to travel from Dallas to Nairobi via Chicago and Brussels and had been issued boarding passes for all three segments of my journey. At the boarding gate in Dallas, I was required to check my carry-on luggage due to limited cabin space. Despite my attempts to explain that I was traveling internationally and would not have access to the bag during transit, my concerns were not considered. I also informed the staff that I did not have a padlock to secure the luggage, but this was disregarded. Consequently, I had to hastily transfer essential items from my carry-on into my handbag. Unfortunately, the onboard experience on the Chicago to Brussels flight further reinforced my dissatisfaction. The cabin crew appeared disengaged, indifferent, and lacking in attentiveness, resulting in a service experience that fell well below my expectations.

Flight was on time and got us to destination quicker than scheduled.

I have very bad experience with United because Vince two weeks that I did not receive my luggage yet

It was okay. Mothers with rowdy children should be invited to sit in front of them.

Good food, overall very comfy. The flight was full so obviously not optimal, but it is what it is.

Flight was delayed by several hours and then cancelled due to weather. But Staff was very helpful getting me on a different flight. United should offer food coupons and tooth brush and paste for stranded passengers

I had a good comfortable seat. There was nearly an hour delay. There was an accident with the champagne, but I was well compensated. These things happen sometimes.

We missed our flight. There was not enough time built into the layover to get through immigration, customs, bagclaim, bag rechecking, and the long trip to another terminal and gate. Kayak really screwed up. We took the bus up to Wisconsin and then were picked up in Brookfield by private car. It was lucky we didnt miss the last bus out.

I tried both on line and by calling the Customer Service line to arrange for a special meal as i have food intolerances. I was under the impression from your service representative that I was successful. I was not. I cannot eat spicy foods and get very ill if i eat bell peppers. I could not eat either menu choice and no special meal was actually ordered. ( your representative tried to order it for a flight that did not have meal service!!! - found this out later). Your wonderful cabin crew managed to put together a fruit, salad, roll and cheese tray for me so I had something to eat. WHY WOULD YOU SERVE SPICY FOOD, WITH NO MILDER OPTION,ON AN INTERNATIONAL FLIGHT???

I liked Quiet people around me. Crew could have helped people with overhead luggage so they aren't moving other peoples bags around and causing problems for people that had there bags there first
