Insights shared by verified travelers who flew the route from O'Hare Intl to the United States 
MatthewFlew with United Airlines-Jul 2026
When in Seattle, take public trans at least to downtown as Uber/Lyft is expensive
Verified travelerFlew with Air Canada-Aug 2026
Pray. Use Apple air tags. That way at least you know where your luggage is
MarkFlew with American Airlines-Jun 2026
Get there early, only one TSA line open and thew queue was very long.
NFlew with United Airlines-Jul 2026
Only do carry on the checked bag was stressful and time consuming.
AlejandroFlew with United Airlines-Apr 2026
expect some delays and be prepared, but once arrived to Lincoln, airport is very easy to navigate since it is very small. Prices are higher than other airports, but that is ok when looking for convenience.
IanFlew with American Airlines-Apr 2026
Lately ORD airport struggles in general often having ground stops. Construction extends travel back to airport so allow 2 hrs. Over past few months, experienced far few delays on United than AA.
SteveFlew with Spirit Airlines-Mar 2026
Bring a seat cushion if you're flying Spirit.
Verified travelerFlew with United Airlines-Apr 2026
Chicago airport is super chaotic. We had come in from an overseas flight and were required to get our checked bags at Baggage Claim and recheck them for our next flight, which took a while. Then after going through a LONG customs line (again) and rechecking my bag, I was told to take a shuttle to a different terminal for my final flight. Even though I never left the building and had no access to the outside world, I had to go through security AGAIN (boots off, dump out my water, wait in long lines…) My advice is to be sure you have at least a couple of hours between flights to deal with the insanity.

travel to ohare is horror - work in extra time
Verified travelerFlew with ANA-Dec 2025
Give adequate time of more than 2 hours for your connection in Chicago O’Hare .. The terminals are not that far apart but still if it’s checked out and check in again process that involves TSA security screening again , 2 hours may not be enough ..
MarcoFlew with United Airlines-Dec 2025
United delayed my luggage twice on flight to Europe (first flight was for an important event) I carry 2 days of clothes in my backpack no matter who I'm flying with United especially so. No less than 2 hour layover to decrease possibility of loss/delay of luggage. Second EU trip my luggage was left in Germany even though my layover was just over 1 hour. Select layovers of 2+ hours although Unite will sell flights with 40 minutes layover (nonsense). 1 hour layover was not enough to transfer luggage in FRA. The last scan was 30 minutes after the flight left (SMH).
RogerFlew with Japan Airlines-Jun 2025
Make sure when you go from one airline to another that your bag is marked properly so they can get it on the right damn airplane. I did that and it still didn’t make it.

Ask for stewards to assist and provide amenities or you won’t get them.

I recommend having movies and songs downloaded on your device.
Dr. JosephFlew with American Airlines-Jan 2025
Be very vigilant about the weather both in Chicago and in Dallas. Adverse weather in either area can affect the trip.
JanieFlew with SWISS-Feb 2025
I think you should prebook food or bring your own food.
Verified travelerFlew with Spirit Airlines-Sep 2024
Make sure you get your seats booked at time of booking or at the least when you check in and make sure you check in at the earliest to have preferred seating.
MikeFlew with American Airlines-Sep 2024
Arrive early, grab a bottle of soda before getting on the plane and open it in the terminal. If you wait until flying the pressure will decarbonize the drink.
Verified travelerFlew with Alaska Airlines-Sep 2024
Not many amenities at the terminal. I would suggest grabbing anything that catches your eye before you get all the way down. There weren't a lot of Alaska flights out of Chicago, and we were at the extreme end of the terminal.
Verified travelerFlew with British Airways-Sep 2024
Easy hop but we sure went to the most remote o’hare gate I think, prepare to walk a mile!
mauriceFlew with Iberia-Sep 2024
You should arrive early, take a lighht snack and be prepared for delays.
HeatherFlew with Lufthansa-Aug 2024
Make sure there's enough time between connections to go through customs and recheck your luggage. They will not let you proceed so you can't even try to run and catch the flight if you want to.
DianaFlew with American Airlines-Jul 2024
Be sure to have name spelled correctly. Two hours early works well.
AlexanderFlew with Spirit Airlines-May 2024
Know your connection options — specially when LaGuardia Airport (LGA) only has buses going to/from the airport to the rest of the city. Luckily, the one to the subway station (Q70) is free-of-charge to ride on!
Verified travelerFlew with United Airlines-Apr 2024
Use the find my gate feature on the flights phone app if available as the airport is a bit confusing
AyannaFlew with Spirit Airlines-May 2024
Fly out of Midway airport instead of O'Hare because its smaller and easier to manage.
PaulFlew with Alaska Airlines-Apr 2024
The flight is long, at over four hours. I would try to get a window or aisle seat to be more comfortable. I would check with other airlines that allow you to choose your seat even if you are in the economy section. I would bring your own food on the plane as the service was sometimes sketchy.
EllenFlew with United Airlines-May 2024
The flight is short enough that full beverage and snack service is limited or not offered at all. On this flight, we were offered orange juice or water. It makes sense that they can't do the full service, and doesn't bother me, but it's something to be aware of.
Verified travelerFlew with Alaska Airlines-Apr 2024
If you miss your flight ask any alaska agent to how and where to rebook the flight.
UzomaFlew with American Airlines-Jan 2024
ORD and DCA are nice airports with plenty of space. ORD is always busy so allow ample time to drive there, drop your bag, and go through security if you don't have TSA pre check.
LaurenFlew with Spirit Airlines-Feb 2024
If you can get by with a personal item, spirit has the best prices often at the best times to fly chicago to orlando for a weekend
Dr. JosephFlew with American Airlines-Jan 2024
Be prepared to walk long distances in Charlotte. Make sure your layover time is sufficient to transition between arrival and departure gates.

Airline reviews

They overbooked the flight! Or they said it was over weight, very unnerving as flying is a gamble anyway. They were waiting for six passengers to give up their seats, before they would board the flight, they were offering $1100. I’m guessing towards the purchase of the next ticket which I would never purposely fly with American Airlines. It was just the only flight available with what I needed. American Airlines is the top two worst airlines to fly with. And then after waiting an hour and four minute delay departing they ended up seating the people that they had asked to give up their seats anyway turns out they were not overweight after all. So all of that in a delayed flight and a delayed landing in Des Moines for nothing American Airlines is in competition with United Airlines for the worst airline to fly with.

The seat was comfortable, but I paid for upgraded seats and they did not state that there was no outlets for devices.

Extremely professional crew there are very friendly and first class. Everything worked well on the plane. Food was to be expected. Drinks were very good. Shout out to Charlie in first class who was an excellent flight attendant.

Thanks for all you do to keep us safe and on time!

I like flying Alaska Airlines. I think the staff are happy, the plane is comfortable, the entertainment reasonable, the food acceptable.

No WiFi. Terrible food. Very long walk to the gate and from the gate after landing. Gate changed without notice.

I really hate the seat assignment at the gate. I understand it is so families can sit together but it caused me and others a lot of unnecessary stress and confusion, enough for me to not fly Alaska again. The app is so awful that it did not even update my seat assignment on the boarding pass but sent me a notification of my seat... it showed in Apple Wallet but not in the Alaska app itself. That only made the stress worse. I think most people like myself prefer to know where they are seated at check in 24 hours before so they don't have to anxiously hang out at the gate the entire time. This is not a good use of your agents time either to be dealing with all of us asking where we are sitting. You should automatically assign the multiple seat purchases to be together before they check in and fill us solo travelers in those gaps as we check in.

Great. Went right to the desk and the people were helpful and kind. I was able to get my boarding pass in under 5minutes. They made sure I received the text.

The flight was delayed so we didn’t get into San Diego until almost 1 AM. Otherwise, it was lovely.

My flight got canceled never left san diego and miss out my fam event

The plane was a rather tired 737-800, with old style small luggage bins. Poor air flow. USB charger in the infotainment system was not functioning. The flight was 2 hours late due to crew rest requirements (not their fault). On arrival in Seattle, waited on the tarmac for 30 minutes with very few updates from the crew.

Very easy to use and convenient, you can perform any action within the same portal

Okay considering we had weather delays which the Pilot notified us of immediately!

Everything could have benn better. Short fly, no food, no entertainment and no wifi.

Stop changing gates. Stop cancelling flights Stop moving my seat.

The staff was frielndly. The plane was terrible, it was too small and should be decommissioned. There were no back seat screens at all. The only beverages we had a choice from was coffee, tea or water. The only bathroom in the back was behind the flight attendant's jump seat and wasn't working. And I literally felt like I was sitting on top of the guy next to me. It was terribly hot in the plane and we had to sit on the tarmac in Chicago for 1/2 hour due to congestion in Mpls. Wouldn't they have know that before they even boarded us so that we could have sat in comfort in the terminal?

This was one of the worst flights I’ve been on in years. I upgraded to comfort and had such an uncomfortable experience. The person next to me was oversized - which I understand - however, they took up their space and mine. I could only use about 50% of my seat space to not be physically touching this person the entire flight and there was no spatial awareness. I also could not use the seat outlet because their body was obstructing it. It was very inconvenient. Their body kept touching me repeatedly during the flight and I felt very uncomfortable. To pay more for an upgraded space and then not even being able to use it was highly disappointing.

It was very cold because the air conditioner was on high power, and my son got sick.

The boarding process was terrible especially with an indirect flight Chicago to Seattle to San Diego was terrible talking about we overbooked a flight idk if I’d take this airline ever again we got off our flight from Chicago to Seattle and we traveled for business and they told us our connecting flight was over booked and their was no seats asking people to take a delayed next flight and they don’t tell anyone coughing to wear masks seats 30A-B were terrible during the flight no one wants to sit next to people coughing all around I don’t want to be sick traveling for work or get sick anytime it’s very upsetting the staff doesn’t take this stuff serious to tell them to wear masks when they see people coughing and sneezing

Delta airlines charge $ 30,oo US DOLLARS for the check in for a suitcase in the baggage hold

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

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.

It was hot and not as comfortable as the flight to Chicago. Must have been a different plane that needs to be worked on or replaced.

The SFO lounge closes at 12 midnight. My flight took off at 2AM

It was extremely hot in the cabin the entire flight, vent air was worn

Have not had a flight out or returning to Norfolk that has not required maintenance, and a gate delay. Properly staff the crew so maintenance can be performed without last minute emergencies on each flight and there is enough staff to have gates prepared for inbound flights. Staff to ensure the safety and on time service vs. profit.

My original flight was cancelled and that affected my trip and my plans and I got no compensation and customer service was hard to reach as well

The flight was delayed by a hour and I wish they had communicated it sooner. No issues on the plane, it did take a while for food to come.

Good flight, regional jet so old and seats could use an upgrade

Couldn't make the flight because connecting flight was canceled.

gate crew was courteous and helpful, flight attendant was nice and friendly once we got going. But we pushed off from the gate relatively on time, then sat there like 10 ft away, for an hour, with no announcement or explanation. Taxiing then took forever, and I get that there was runway congestion, but would be helpful to keep us posted on whats going on

The power outlets were not working for my row. Also felt like the seats have gotten smaller. I was in the window seat and felt like suffocated, as the two passengers next to me were tall and wide.

Terrible. The flight I booked had a convenient departure time. Quick layover. And an arrival timed that worked for the people who had to pick me up. Thanks to delays and rebooking I got none of those things

I had my flight of Cedar Rapids. THen Chicago to Boston. Flight out of Cedar rapids was delayed by 12 hrs. Had to drive to Chicago to catch my flight

Long delays to board due to mechanical issues with plane.

Flight was delayed, boarded, sat at the gate for more than 30 minutes, left the gate then waited on the pad for another 30 to 60 minutes then returned to the gate, deboarded and was cancelled... alternative flight was not booked automatically. Waited in line for 30 minutes but fortunately an alternate flight to a different destination was found ... no thanks to the travel agent used by kayak

The flight from Milwaukee to Dallas was great the staff absolutely amazing. After that EVERYTHING WENT DOWN HILL!!! ABSOLUTELY HORRIBLE!!! WILL NOT FLY THIS AIRLINE AGAIN

I was very unhappy with the lack of communication from the cockpit. It took close to a half an hour before we took off after the doors were closed, and we got no announcements as to progress. It would be nice to get some acknowledgement of the situation and updates as to when we are taking off.

During the flight I suddenly felt very sick, and no one from the crew even tried to help me or check on my condition. They seemed completely indifferent and showed no concern for my well-being. I was very disappointed by the lack of care and compassion. I hope the airline improves its customer service and trains its crew to respond better when passengers need assistance.

Flight was canceled. Most upsetting was message from Kayak, stating that the flight was canceled and click with Kayak for details regarding rebook, refund details. THERE'S NO INFORMATION PROVIDED BY KAYAK EXCEPT THAT FLIGHT IS CANCELED. AND NOW THIS SURVEY TO FIND OUT HOW WAS THE FLIGHT !!!!!!!

Better than expected. Staff were friendly and nice on both flights.

Just know that everything, and I mean everything is “ala cart”. 60$ just to put something in the overhead bin. I will never fly Frontier again nor do I recommend them to anyone else.

Great for the price. No wifi or entertainment, but gate agents and crew were fantastic and we boarded quickly and left on time.

Our flight was canceled for no known reason. We weren’t told until we were checking in at 5:00 am. This was after our last flight with Frontier where we sat on the plane for three hours (not an exaggeration) before we took off because of a mechanical issue. We won’t be flying Frontier again.

I didn’t have enough time to catch my connecting flight and had to use a different Airline. I will be requesting a refund.

I brought a ticket and car rental through Travelocity. There was no where to add a KTN. So I thought i’d add it by looking up ticket on frontier website. I tried 3 times with the frontier chat bot to add my KTN it never updated my boarding pass. So then I tried showing up early to do it in person at the airport. The first employee update my ktn in the system and gave me a new boarding pass. I was sent back by tsa to join regular line. Then I was told to add my Ktn. It would cost me $25 extra. Given the length of the cue I did pay. Congratulations! BUT I will NEVER fly frontier again. Plus the plane was very old. It had actual ashtrays and old looking tray backs. Worst travel experience ever. Im warning my friends and family not to use frontier ever.

It was delayed 9 hours for operational reasons, despite the plane arriving to the airport on time.

Was just ok with over selling I guess. A lot of people in a short space and when we finally arrive i20 minutes, waiting to get out from the plain because we were waiting authorization for out boarding? Something like that.
