ScottFlew with Air Canada-Jun 2026
Make sure you have enough time between connecting flights so ½ of your baggage doesn't miss the flight and take another 24hrs to show up
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
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.
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.
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.
MamiFlew with Japan Airlines-May 2026
I did not find particularly good stuff in Entertainment (movies and TV), so you may want to bring what you like.
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.
Verified travelerFlew with American Airlines-Apr 2026
travel to ohare is horror - work in extra time
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).
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
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.
Verified travelerFlew with United Airlines-Mar 2025
If you can select your seats in advance please do
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.
AndreaFlew with United Airlines-May 2025
Ask for stewards to assist and provide amenities or you won’t get them.
Verified travelerFlew with Royal Jordanian-Apr 2025
I think you should choose another airline unless you obligated. Prepare yourself for no wifi The crew are polite but somewhat non co-operative Charge your phone before flight because charging station are non-working
Verified travelerFlew with EVA Air-Feb 2025
Coming from Chicago which is also a busy airport, I recommend checking in online prior to thetrip. Make sure luggages follow the required weight and go directly bag drop. You may also want for the attendants to print your boarding pass with the recent details on boarding gate number and zoning.
Verified travelerFlew with ANA-Jan 2025
Consider light carry-ons to give yourself stretch room for economy and quick onboarding and off boarding especially with connecting flights.
TFlew with Scandinavian Airlines-Jan 2025
Don’t forget you can pinch and slide the headrest up and down for maximum sleeping comfort.
Verified travelerFlew with American Airlines-Dec 2024
I recommend having movies and songs downloaded on your device.
DarylFlew with Cathay Pacific-Jan 2025
They are strict with carry on and they weigh it upon check in.
JanieFlew with SWISS-Feb 2025
I think you should prebook food or bring your own food.
valerieFlew with Air Canada-Jan 2025
“Meal” usually means more than a light snack. I thought what they served was an appetizer not the total meal. So I’d eat before or bring 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 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 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 Cathay Pacific-Nov 2024
First flight to hkg but been to asia many times. Most airlines have frequent beverage service to combat the dehydration that comes with a long flight.
DevikaFlew with Etihad Airways-Sep 2024
I wish I had known how much walking I had to do to the transfer terminal from landing to transfer gate.
Verified travelerFlew with Porter Airlines-Sep 2024
Please start bags check-in at least 2.5 hour before flight and finish at 30 min before flight.
Verified travelerFlew with United Airlines-Sep 2024
Be prepared to wait in long line for boarder control. Allow enough time for your layover
mauriceFlew with Iberia-Sep 2024
You should arrive early, take a lighht snack and be prepared for delays.
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!
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.
WilliamFlew with EVA Air-Jul 2024
Wear compression socks or prepare for massive swelling of your feet and ankles.
DianaFlew with American Airlines-Jul 2024
Be sure to have name spelled correctly. Two hours early works well.
MikeFlew with British Airways-Jun 2024
Make sure you check the plane type and economy seating space.
EstherFlew with Ethiopian Air-Aug 2024
Eat before boarding the food is smelly. Do not sit near a toilet
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.
Verified travelerFlew with Alaska Airlines-Apr 2024
If you miss your flight ask any alaska agent to how and where to rebook the flight.
FreddieFlew with Icelandair-May 2024
If you’re in business class board first to avoid queuing
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.
RogerFlew with ANA-Feb 2024
The extra leg room and been able to recline better is worth the extra money. I bidding on the premium and offered the least they would accept and got it.
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.
RyanFlew with EVA Air-Jan 2024
Bring things to make the seats more comfortable
Verified travelerFlew with United Airlines-Jan 2024
I always expect issues with United but there doesn't seem to be another airline to use. Advice: Give yourself and extra day to get anywhere - don't be in a hurry to get home either.
