NFlew with United Airlines-Jul 2026
You need to check your own bags in, meaning you wait I line to print the ticket, put the tab on yourself and then go to another line to make sure the suitcase gets placed on the plane and under the 50lb weight limit. A lot of back and forth.
JoanneFlew with United Airlines-Jun 2026
The runway to gate took a bit of time. So if you have a short layover pay for a seat up front .
kelechiFlew with United Airlines-Jul 2026
Leave enough time for connecting in Chicago. It’s a very busy airport
DeepaFlew with American Airlines-Apr 2026
The TSA precheck feature is useful, and the security checkpoint to gate walk is around 20 mins, not too bad.
CupcakeFlew with Alaska Airlines-Apr 2026
Please bring a water bottle for hydration during the flight.
Verified travelerFlew with American Airlines-May 2026
Don’t plan on using overhead bin space if you board after group 4 on any American flights using 737’s. They are frequently full by the time the 4th group boards. And, if your carry on bag has to be checked at the gate, be sure it has nothing breakable inside, as it may not survive that process.
Verified travelerFlew with American Airlines-Apr 2026
Chicago has a enormous airport so be ready to walk and transfer to international flights by train via terminal
Dr. JosephFlew with United Airlines-Apr 2026
Always keep track of the weather at both locations and where the inbound flight is coming from.
EricFlew with American Airlines-Apr 2026
The connections in Chicago can be tricky. Make sure you have enough time to make your connection.
Verified travelerFlew with American Airlines-May 2026
Arrive airport early, esp if checking bags - std procedure but vital here
Verified travelerFlew with United Airlines-Apr 2026
Make sure the flight you select has more than 3 hours as time allotted for transiting to another flight. Most of United Airlines flights get delayed and if you don’t have enough time, you’ll be missing the next flight for sure. Have extra budget for shelter expenses because most of the economy tickets does not qualify for shelter accommodation/ voucher when your flight is delayed.
YesicaFlew with United Airlines-Feb 2026
Utilize the mobile app of your airline it will give you all the updates and information you need
BillFlew with Frontier-Dec 2025
Wear comfortable clothing and make sure you layer. We went from 80o to 30o,

Pay extra for Boarding Zone 2 to make sure your carry on, gets on the plane.
Thrinadh KumarFlew with United Airlines-Dec 2025
Flight is conjusted. Difficult to sleep. Carry pillows and sleep well beforeyou travel
StephenFlew with United Airlines-Jan 2026
If you're trying to make a connecting flight make sure you allow PLENTY of time between flights or be prepared to miss the next flight. Make sure to use the restroom at the last possible moment before landing because you could be sitting on the taxiway for 5 more minutes... 5 more minutes... 5 more minutes... until it's been nearly 2 hours. Don't trust the airline provided ETA provided by apps they don't update it until long after you're delayed. If someone is showing up to give you a ride, make sure they have hours to wait for you.
JeremyFlew with United Airlines-Nov 2025
Beware short connection times on flights connecting in Chicago.
DouglasFlew with American Airlines-Jun 2025
Check your app for delay notices. This notice did come out early in the morning - I failed to check it. Checking it could have saved 4 hours at the airport
Verified travelerFlew with British Airways-Jun 2025
Make sure your luggage receipts have the ID numbers on them
Verified travelerFlew with Air Canada-Apr 2025
Chicago is a huge airport, wear comfortable shoes if you're looking to make a connection. It might be a 15 minute speed walk. Jacksonville is a little more compact and easier to navigate. Lots of food and beverage options in each.
StaceyFlew with American Airlines-Feb 2025
Don’t be that person who holds up the plane because of your carry on. Whether putting in over bin (able to lift it on your own) or refusing to not listen when space is full and need to check it.
Verified travelerFlew with United Airlines-Dec 2024
Get to know the airport plan in advance because it is a confusing one.
LisaFlew with United Airlines-Dec 2024
Turn on your data or the wifi in case gates change.
valerieFlew with Air Canada-Jan 2025
Usually it is unreliable - always leave lots of time for connection.
StephenFlew with United Airlines-Jan 2025
Don't bring a carry on roller bag. It won't fit. They will gate check it. It will take forever.
RodFlew with United Airlines-Sep 2024
Yes! Don’t reserve a flight with less than 1 1/2 hour connection time or you have a good possibility of missing your connection.
FrancisFlew with United Airlines-Sep 2024
Check the weather, or bring a. Raincoat! Being from sunny California, I forget it isn’t always sunshine in other states!
GeraldFlew with Alaska Airlines-Oct 2024
Book a flight as early in the day as possible to avoid incoming flight delays.
BrianFlew with Air Canada-Oct 2024
Be prepared for a labyrinthine experience traversing the various levels and passages of the Toronto airport. Bring quality walking shoes, as it is likely well over a km in total walking time.
AdamFlew with Southwest-Oct 2024
Arriving T5 at ORD on Southwest is often a LONG walk, with no moving walkways going out, to baggage claim / pickup.
DinaFlew with United Airlines-Nov 2024
Be prepared for delays and plan to check your luggage. Overhead bins are ⅓ the size of a typical bin.
KimFlew with American Airlines-Nov 2024
Bring extra foods and buy extra drinks bring your meds
LeoFlew with United Airlines-Jun 2024
Get precheck TSA if you’re flying in early morning. Get a seat on the right side of the plane if you want to see sunrise.
Verified travelerFlew with American Airlines-Jul 2024
Fly out the night before you have anything to do in Chicago so you don’t get delayed and miss out on plans
JenniferFlew with American Airlines-Jul 2024
Both the Charlotte and O'Hare airports are large and well organized. Wear you comfy walking shoes and enjoy the journey!
CameonFlew with Frontier-Jul 2024
Fly Delta! Book directly through the airline, not a second booking party.
GailFlew with JetBlue-Jul 2024
Prepare for a long wait after you actually touch down. Ohare Airport is HUGE and you can taxi for a long time.

Budget if you’re planning on shopping for meals or souvenirs at Sea-Tac, it’s not cheap.
Steven AnthonyFlew with United Airlines-Aug 2024
Don't take the 6am flight. Airport security and customs only open at 430am. So if you show up the recommended 3 hours before, you're waiting in line for nothing

Check-in using the United AirLines app to access your boarding pass. Arrive at least two hours early at LAX airport.

MichelleFlew with United Airlines-Apr 2024
Bring water on board and charge your devices in advance.
EllenFlew with United Airlines-May 2024
Greenville airport is small, getting through security won't take too long (particularly if you have Precheck). Be prepared to walk for 10-15 minutes from your arrival gate in O'Hare to your next departure gate, if you have one. Sometimes those gates are really close together, but my experience is that they are typically farther apart and require a solid walk.
Verified travelerFlew with Southwest-May 2024
Leave plenty of time to get your bag in Chicago if you check one. Took 45 minutes to get my bag this time.
Verified travelerFlew with Alaska Airlines-Apr 2024
If flight gets delayed. Be sure to ask the airlines you traveled with, to rebook the next available flight immediately.

Ask for assistance. Chicago is huge airport 🛫 and can get lost easy.
Verified travelerFlew with United Airlines-Mar 2024
Carry-on baggage sizing for United US bound flights appears to be much smaller than for Canadian flights, which forced me to check my bag at the last minute. So check online ahead of time
