Flights from Europe to O'Hare Intl: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Europe to O'Hare Intl 
Verified travelerFlew with Austrian Airlines-Sep 2026
Never plan any close connections in O'Hare. I give myself at least 3 hours if I have a connection. Nothing is convenient and if you need to change terminals, and you usually do, it takes forever. In addition, customs takes a long time. I entered the UK more easily than I got back into the country of my birth. Heathrow is not bad unless you need to go from any other terminal to Terminals 4 & 5. That is difficult bc there is no clear signage. Don't be afraid to ask for help. I have found people ready to help, especially if you are a senior.

Bring a foam pad, your butt will thank you
GinaFlew with ITA Airways-Jul 2026
We had to take a bus to the plane and get on from the tarmack. Just leave enough time to get through that process too.
MichelleFlew with TAP AIR PORTUGAL-Jun 2026
Very strict on weights for hand luggage and sizes. Would fly again and just plan to check a bag
Verified travelerFlew with Lufthansa-Aug 2026
please don’t recline all the way back without notifying and getting approval from person behind you
AndrewFlew with LOT-Jul 2026
The lounge before the passport control is bigger and has more options generally.
mary kayFlew with United Airlines-Jul 2026
Make sure you get to the airport three hours early in Athens the security lines are a nightmare. They are pulling other airlines out of the line ahead of you. They are pulling other passport types out of the lines ahead of you. You will stand there forever, no matter what clearances you have. Avoid Chicago airport at all cost. The place is falling down. They are elevators are out of order a few elevators that they have have lines so long that you will never get through before your flight takes off. People with carts of luggage are trying to get on the elevators with the handicap. It is a total zoo and if the temperature is 95°, the Air Conditioner can only cool to 89°. No you’re going to sweat to death.
Verified travelerFlew with SWISS-Aug 2026
Plan enough time at Zurich. The procedure at the airport, especially boarding is very chaotic. No signs telling passengers to get in line to get your documents checked a second time before you get in line for boarding. Lines were all over the place with approximately 200 people,, others trying to cut through. Airport staff not controlling the situation.
TFlew with Scandinavian Airlines-May 2026
Go through passport control as early as you can. The wait was very long and people nearly missed the flight.
Verified travelerFlew with United Airlines-Feb 2026
Purchase a face mask device that fastens to the headrest that keeps your head supported. You will sleep better and avoid shoulder, neck, and back psin if flying basic economy.
JohannaFlew with Aer Lingus-Feb 2026
Are Ling’s was great, and boards from the back of the plane, which made boarding way less chaotic and much quicker.
KEVINFlew with Lufthansa-Dec 2025
Don't buy business class. It"s a relatively short day time flight. and not worth the extra expense. Stick with premium economy.
Verified travelerFlew with British Airways-Jun 2025
I wish I'd known that there were food and shopping opportunities at the B gate area. This was a lovely, NOT busy place to spend time. I'd have gone directly there if I'd known. Definitely a nice place to wait.
Verified travelerFlew with Turkish Airlines-Mar 2025
"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!"
ElizabethFlew with Iberia-May 2025
Get to Rome airport a bit early. The lines for passport control can be long if you have a US passport. The signage can be confusing, but once you figure it out it is easy. Staff at Rome airport are very good and the lines were not bad there. Just security and passport control.
Verified travelerFlew with British Airways-Apr 2025
Make sure to allow ample time between connecting flights. I have to hoof it when I realized that TSA required bags to be picked up and rechecked.
Verified travelerFlew with Lufthansa-Mar 2025
Beware the long distances at O’Hare terminal 5. Moving walkway help, but it was 1/2 mile or more from gate to passport control
MichaelFlew with British Airways-Apr 2025
Have a light luggage as much as you can. Boarding gate walk is not a joke.
MaryFlew with United Airlines-Jan 2025
Bring your own food. Chicago airport is extremely large....we walked nearly 4000 steps from landing to customs....very difficult for people over 70 years old.

Gate 10 is a train wreck because there are multiple gates distinguished by a letter following A10. If possible get there as quickly as possible to find the appropriate gate.

Give yourself enough time to go through US Customs in Dublin.
HeatherFlew with Lufthansa-Aug 2024
They are super strict on carry-on size and weight. I have never seen an airline weigh a carry-on before. If you are flying through Germany, make sure to alott yourself extra time to stand in a giant line for a passport check, even though it was already checked when boarding to Germany (not sure what could have changed with it during the flight!). They had given some of our seats away on our connecting flight because we barely made it to the gate in time for departure.
Verified travelerFlew with United Airlines-Apr 2024
We opted for Premium Economy and while more expensive, it’s definitely worth it on a long flight. Quieter, more room, and included a checked bag per passenger. The seats are much more comfortable. The only downside is the restrooms. PE is supposed to use the restrooms at the back of the plane even though there are bathrooms right in front of PE for first class. Stupid, the stewards kept locking those bathrooms and there was always a long line for the restrooms at the back. This was on United. We didn’t have this issue on Lufthansa PE.
EmilyFlew with British Airways-Mar 2024
Bring as few liquids as possible or put them in checked bag. They are very strict at Heathrow about all of them fitting into one small ziplock bag
JdubFlew with Scandinavian Airlines-Apr 2024
Remember to make time for passport control when going back and forth. It's after security. I was a little confused as a first time traveler.
Verified travelerFlew with Lufthansa-Mar 2024
Avoid Frankfurt and O'Hare if you can. Use Amsterdam as your European hub and Minneapolis or Dallas as your hub in middle America.

I have flown with LOT several times and regret it every time; however, they are the only airline that offers the direct flights I need. Boarding was awful. I was alone with 3 children, including an infant, and we were forced to stand in buses packed like sardines. Then, for such a large flight, there was not even a gangway. I was expected to carry a baby, a carseat, and luggage by myself up the dangerous steps into the plane while the crew RUSHED me. The crew was very curt, cold, and inattentive. No one offered any assistance or sympathy to me alone with kids. There was no ventilation or AC in the plane.

No one offered any assistance or sympathy to me alone with kids. There was no ventilation or AC in the plane.

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.

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!

I was in the premier economy and enjoyed the room and the comfort. Although I will say that it would take a real expert to make the location of the place to plug in headsets and chargers more difficult. With all of the room available it makes no sense to bury those connections and to make it so difficult to use them. The couple in front of me needed to use the cell phone light in order to see where to plug in a charger. The seats are comfortable and the food was good.

No way to add a bag without getting in line at the counter, which took at least half an hour. No WiFi.

The preboarding and the gate organizing management was poor, unorganized and mismanaged. While standing in the business line I kept getting ignored and the personnel kept checking in others, right in front of me until I finally spoke up and pointed out their clear signs of ignoring me while patiently waiting to be checked in. Once checked in the gate the personnel kept chit-chatting and not managing which group is to board, being totally nonchalant, unorganized and behaving amateur-like . Very unprofessional and unlike the quality the Austrian Airlines brand otherwise provides. The crew on the plane are always fantastic and the best. What a shame the crew on the ground was so mediocre.

Flight delayed with no explanation. Boarding was confused (proceed to plane, go back to waiting area).

Last few years I didn't not have great experience with United Airlines.

Short flight. Bare bones and kinda seeming like an older plane. But got me there on time and that's what counts. Perfectly fine flight all the way from start to finish.

My Austrian Air flight from Montenegro to Vienna was delayed by three hours because their plane de-icer was broken and they had to wait for the sun to come up before the ice could melt. This meant we missed our United flight altogether. So I can't speak about United, but I was not impressed by Austrian Air. They made us check in two carry on bags for a 60% full flight, and the bags didn't find us in the US for ten days. The re-routing they arranged included an extra leg, a midnight taxi ride across New Jersey and New York, and a five hour sleep in a hotel. Not impressed.

I been flying with Austrian for few years, they never failed me.

Vienna airport is a zoo Agents directed me to the wrong gate and then the wrong line Lounge is so crowded no place to sit Not enough bathrooms anywhere On the flight they asked for medical attention While I attended to the problem they forgot my food when I got back They forgot to give me water at night Waited 1 hour for bags Agents didn’t know which Shute the bags were coming to so it was between 2 places

Food: my selection was pasta with vegetables, though it was potatoes not pasta. Breakfast was 2 rolls and some sort of spreads— not sure what they were. Worst thing was that we had to wait for over 90 minutes for our bags to show up at O’Hare

Bussing in a major flight is idiotic. Cabin was too warm. Food was bland and felt old

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.

Excellent food and service on my international flight. Most notable is the food provided by Turkish even for coach passengers is very good.

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.

Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.

The counter person at the gate was rude and demeaning, to the point that I wouldn't fly this airline again.

Crew was great. Seats are cramped and uncomfortable and I’m a small person.

Awful. Delay after delay. And then again on the tarmac.

Kept changing the takeoff time and the moved it up so arrived when boarding had already started. Then sat waiting to taxi in for a long time

Food was not Good Nuts came very wet & not tasting Good Main course I asked for Steak they got me Chicken because they don’t have more !!!!

It cancelled and we were unable to catch our connecting international flights.

Leaving at 7 when scheduled to leave at 4:20 - you tell me. Understood there was a ground stop. Then having to "reboot" the plane because of a lighting strike, also understood. But basically the flight was a "clusterf#$%".

On boarding crew at the airport called in the boarding numbers too early meaning before the previous line was completed resulting in later numbers getting to board ahead. Also she asked those who boarded from number 3 to have the tags in their carry-on bags and leave it in the jet bridge. Most of the overhead bins were empty though. This is more work for the ground staff in addition to more inconvenience for passengers waiting to get their carry-ons from the jet bridge.

ok, butt flght was delyed for 2,5h from Frankfurt, and next Flight to Columbuse same

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. To my surprise, upon arriving at Chicago Airport, I observed numerous international travelers boarding with cabin bags that were significantly larger than mine. This experience left me extremely disappointed and led me to decide against using United Airlines for future international travel, a sentiment I have also shared with friends and family. 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.

I want to highlight the crew members and their excellent work and professionalism. They work hard to make a long trip the most comfortable as possible, the food and drinks they offer are pretty good. And they are always asking if you need something else. I have had experiences with other airlines where you have to basically beg for a bottle of water. This is not the case. Highly recommended!!!

the blanket was great and pillow helped. really need a toothpick packed with meals

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

Very good. Comfortable and I felt well taken care of from start to finish

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