Flights from the United States: the best tips from KAYAK users' own experiences

Insights shared by verified travelers who flew from the United States to anywhere 
Verified travelerFlew with China SouthernLAX-CANJun 2025
Passports are everything when traveling in China beginning with your flight! Keep it handy for every transition! Also the flight boards in the airports don’t always show every flight. If you don’t know Mandarin, practice a few phrases or questions such as to ask about your flight gate, or have a translator app ready. There aren’t many English speaking employees at airports or airlines. Also, unless they are under 30 years old, most Chinese folks know traditional Mandarin not the new simplified. Also many general workers are likely of a regional dialect so if you need help look for someone that appears younger and in a customer facing role like a gate agent. The translator apps are pretty good but limited. Give yourself a lot more time to get around than you think you need. Most importantly, everyone was super nice and helpful.
Verified travelerFlew with DeltaANC-MSPJul 2025
Check the exit row seats! On my plane one seat on each side had a seat with no seat in front of it for easier emergency exiting, giving that person a huge amount of leg room. The downside is that the seat sides are solid with tray tables in the armrest, so there’s no “overflowing” into the adjacent seat. For the tall, fit gentleman next to me it was a score.
Verified travelerFlew with Alaska AirlinesOAK-SEAJun 2025
Oakland is a nice small airport. Getting through security was a breeze with TSA precheck. We did have to stand in line for about 20minutes to drop bags as there were no agents at the counter. I had the most delicious crispy Al pastore taco near face 14
Verified travelerFlew with Hawaiian AirlinesMSP-PDXJun 2025
Minneapolis is just a great airport. Signs to the rental area were a little unclear but that was not a huge deal as the tram only goes to one stop so you can’t get too misplaced.
FraxysFlew with American AirlinesONT-DFWJun 2025
Bring an empty refillable water bottle/container through TSA and fill it up as soon as you pass the security check. The water station is available to the left and to the right of it.
DanielleFlew with Alaska AirlinesJFK-ANCJul 2025
Have personal headphones for in-flight entertainment as personal device is utilized. Also bring own supplies for sleeping during flight (blanket, pillow, ear plugs).
MikeFlew with Alaska AirlinesKOA-SJCJul 2025
Be prepared for your flight by purchasing a meal before departure, and by all means spend the eight bucks for inflight WiFi.
AndrewFlew with United AirlinesIAH-LHRJul 2025
United really looked after me, just make sure you arrive good and early to ensure an unpressurised check in
LinFlew with LATAM AirlinesJFK-LIMJun 2025
Board as early as you can so you won’t be forced to check in your carry on bag.

Give yourself extra time. Love the self check in options.
Verified travelerFlew with LufthansaJFK-MUCJun 2025
Wearing comfortable clothing is really important. ( it’s a long flight)
RobertFlew with Philippine AirlinesHNL-MNLJun 2025
Ensure your seat assignments are correct before accepting boarding passes!
CarlosFlew with Alaska AirlinesSAN-AUSJun 2025
Get to the San Diego airport early. The security line will be long. Also, if you're flying Alaska Airlines and don't check in online, go to the Alaska Airlines "Agent Assit" counter first. Don't be like me and go to the Alaska Airlines "Bag Drop" line. That was a bit confusing. If you're flying Alaska Airlines.
KeithFlew with IcelandairSEA-KEFJun 2025
The boarding was good but the line for check-in is pushed off to the side because of the recent construction. It’s fine but cramped as people jostle to get checked in. Also, we weren’t able to use our online check in and printed boarding pass so we had to basically check in twice.
TorieFlew with Spirit AirlinesBUR-LASJun 2025
Be aware that you pay extra for even a carry-on suitcase, but you can bring a personal item at no extra charge (purse, computer bag, etc). There is typically turbulence going into and out of Las Vegas during the warm season.
KeithFlew with Hawaiian AirlinesOGG-LAXJul 2025
Check your seating assignment thoroughly when you check in to ensure it's the seat you paid for. Flights number, planes, seat assignment, departure times can change at moment's notice, so make sure your confirmed flight assignment in 100% correct!!!
Verified travelerFlew with FrontierPDX-DENJun 2025
Make sure your carry on bag meets the size limit as bin space on plane is limited. Check any bags online in advance to avoid extra charges for using agent at the airport.
KimberlyFlew with DeltaSEA-FLLJul 2025
Ask for headphones to watch screen movies as all of mine are bluetooth and that will not work. Bring own food and wait until plane moves before hooking up to Deltawifi.
DouglasFlew with American AirlinesHSV-ORDJun 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 Alaska AirlinesRDM-PDXJun 2025
It is a cute little airport with one coffee stand that gets a very long line, so be prepared if that’s something you need at o dark thirty.
Verified travelerFlew with Hawaiian AirlinesSEA-ONTJun 2025
Make sure to be there on time because the bag drop off can be a little complicated and it takes quite some time to get to the gate.
EdmondFlew with LufthansaEWR-BCNJul 2025
The Airtrain service is now under construction, so one rail is closed. So it would be better to get to the airport by not using the train...
Verified travelerFlew with Hawaiian AirlinesIDA-SEAJun 2025
Idaho Falls is not a large airport, so it was easy to find my way around. Take a meal if you want more than a snack.
Mary MargaretFlew with Aer LingusIAD-DUBJun 2025
Some people may be required to check their carryon bags, depending on flight, plane size, check-in crew, etc. Also, taller people should purchase aisle seats.
Verified travelerFlew with Aer LingusBOS-DUBJul 2025
Whatever airline you choose, spring for a class with more leg and overall body room than economy (or whatever the cheapest class is called).
MaryFlew with DeltaSAN-ATLJun 2025
San Diego is great airport at terminal 2. Not so great for Uber pick up past terminal 1 diversion When busy.
himanshuFlew with Aer LingusEWR-DUBJun 2025
Eat and drink before boarding. Snacks. Hand gel and surface wipes . Don't expect a window if in a window row.

Large number of passengers on the flight so arrive early to the airport and to the boarding gate

Try and bring your own water on board
Verified travelerFlew with FrontierSEA-PHXJun 2025
Wish I had known the seats were so uncomfortable. Wish I had known checked bags and carry on bags were 75 each. Wish I didn't have to wait so long in line with only one clerk working. Wish I had known we were going to have to take a bus from the gate to our airplane. Wish I had known the seat space is smaller than any other airline I have flown. I do not recommend Frontier.
Verified travelerFlew with Alaska AirlinesBZN-PDXJun 2025
The Bozeman Airport has NO seating for spreading out. All the seats are simple chairs with armrests. If you have a delay or are trying to sleep while waiting, you will have to sit upright the whole time. There are also very few outlets. Again, if you’re delayed or spending extra time at BOZ and your phone battery is running low, good luck.
Verified travelerFlew with FrontierGRR-DENJun 2025
Don't purchase vouchers with connections on the cheaper flights (such as frontier or Spirit), you're bound to have a delay. middle or more expensive airlines are more reliable, comfortable, and have consistent pleasant staff working.
RogerFlew with Japan AirlinesORD-PITJun 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.
LeoFlew with American AirlinesLAX-CLTJul 2025
Avoid LAX. Personal experience. I have had less chaotic process in Ontario, CA airport. If transferring through another AA flight, consider Phoenix airport.
Verified travelerFlew with British AirwaysEWR-LHRJun 2025
Pay for your bags at time of arrival and not through a third party site, they will rip you off!
MarkFlew with United AirlinesDEN-NRTApr 2025
For that long of a flight, spend the extra money for more leg room if you can afford it and don't waste you money or miles on United's wifi. Shout out to United's new check in/baggage procedure in Denver... It took a minute to navigate it but once I did... I wish all airlines would do similar.. it was fast and easy!!!
Verified travelerFlew with Alaska AirlinesSEA-DENMar 2025
Alaska Air is very efficient & on-time so allow enough time to get luggage, go thru Customs & Immigration, & long security lines. Terminals in SEA are readily accessible by trains but more signage is needed. Fortunately, Information booths are everywhere & are manned by very helpful staff.
KimFlew with American AirlinesBOS-PHXMay 2025
Bring something to eat especially if you are connecting flights. Biscuits do not cut it, if you get restless make sure you have something to help such as an essential oils that help calm muscles or restless legs.
Verified travelerFlew with Spirit AirlinesMCO-EWRMar 2025
For budget travelers, this is a good airline. Stick to the luggage dimensions, bring a snack and a book or entertainment that does not require WiFi and you will get to you destination for a great price.
LeoFlew with Spirit AirlinesFLL-MSYApr 2025
Get to the airport a bit earlier to have a snack or meal prior to boarding. It’s a short flight, about 1.5 hours, so each airport has plenty of choices.
Verified travelerFlew with Spirit AirlinesLGA-DFWApr 2025
LaGuardia has gotten so much better since the renovation. And its convenience to Manhattan is second to none. Terminal A had a super short security line too, which was nice
Verified travelerFlew with Hawaiian AirlinesSMF-HNLMar 2025
Bring a blanket for the flight and your own snacks. WiFi on the plane was great and the leg room in our seats was good also
Verified travelerFlew with American AirlinesPDX-DFWMay 2025
Check out the barbecue shacks in the airport. I didn’t; regret that. They also have an in-terminal food delivery service. Maybe run by Uber Eats
MelodiiFlew with FrontierLAS-ATLMar 2025
It is a good idea to find out if your flight will have Wi-Fi, so you can plan out your communication options for the flight.

Super easy airport, TSA is organized and efficient. Lots of food choices once at the gates. There is a piano player on a grand piano!
MaryannFlew with United AirlinesSFO-EWRMar 2025
Bring your own food with you. Airport and airline food is expensive and you WILL need something to eat on such a long flight.

JoeFlew with IberiaORD-LHRApr 2025
Get there early. Nice airport options while you wait.
Verified travelerFlew with IberiaORD-LHRMay 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.
Verified travelerFlew with Alaska AirlinesPDX-MFRApr 2025
Arrive 2 hours early, figure out the location of baggage/pass kiosks and gates, minimize all that excess carry-on stuff people seem to lug onto the plane. Also, the airline should do like some did in the old days, board in this order: 1)first class and special attention, 2) then board from the BACK OF THE PLANE TO THE FRONT OF BUSINESS/COACH. Why is this not a thing? Used to be soooo much more efficient, no one in anyone else's way.
Verified travelerFlew with Copa AirlinesRDU-PTYMay 2025
Get to the airport 3 hours early, even with the help of the kiosk, you may still need verification from an agent at check in and by a certain time they leave the check in desk, and you may have to rebook. even if you get there early and the flight delays for 2 hours and altogether you have been waiting for 5+ hours. If you want to make your flight, you have to get there early and wait
GeraldFlew with American AirlinesSJC-PHXMay 2025
SJC is physically a smaller airport. The gates are closer and TSA has shorter lines, They are not subject to weather delays as much as SFO. On the other hand SFO offers more flight options, both in the number of flights each airlines flies and the number of airlines serving the airport.
Verified travelerFlew with FrontierRDU-SJUMay 2025
If you are in the first group to board, stay standing early next to the gate entrance so you really enter first. Otherwise you end up entering all groups at the same time and will loose your carry on space over your seat.
HFlew with American AirlinesLAX-TUSMar 2025
It’s really easy. The only complaint might be the tram back to the last terminal to Tucson. It runs about once an hour and there is only one food option when you get there. Just give yourself plenty of time..
Verified travelerFlew with Hawaiian AirlinesHNL-OAKMay 2025
Make sure you give yourself time, our gate was a long walk down but noticed there was a shuttle option? Because of timing I decided to walk it, I wouldve liked to take a shuttle.
Verified travelerFlew with Alaska AirlinesSEA-CLEMar 2025
If you have a rental car, give yourself time to catch the shuttle to the airport. Also be aware traffic is awful and will often be standstill on the way to the airport.
John William MichaelFlew with American AirlinesLAX-SATMar 2025
Watch the departure gate. Some are distant requiring shuttle service and there is minimal to non existent food, beverage, and usual shopping at these gates. Take food with you before boarding the shuttle.
Verified travelerFlew with EVA AirSEA-TPEMar 2025
Arrive early at the airport. Bring personal items like toothbrush and toothpaste if needed because it’s a long flight. If you’re flying with Eva, I don’t think you’ll need more than that.
RobinFlew with Alaska AirlinesLIH-SEAMay 2025
Get to the Lihue airport 3 hours before the flight because there are multiple security steps and extremely slow security processing. Even if you have TSA precheck/global entry.

Again snacks unless you want to eat prior or order ahead of time for flight. Wear layers as usually warm or as my case a little cool.

My mom told me prior to boarding an airplane I should empty my bladder. As I age, that advice becomes more sage.

As long as you show up before boarding begins, you should still be fine to check in a bag for the flight.

Fly out of Houston Hobby right now. All the construction going on at Houston Bush makes arrival and checkin a nightmare. Almost every flight must checkin at Terminal C regardless of what gate/terminal you actually depart out of. I missed this note on the United app and took 2 elderly people traveling with me to terminal A to checkin and had to lug them around the subway underground to get back to C and that took forever.
LawrenceFlew with United AirlinesSFO-HNLMay 2025
Get to your gate early!!! Very little seating at/near gates 19, 20, 21 and 22. The last couple of flights, American boarding (very different gates) has been very straightforward. The last time on United, boarding at gate 19 was bedlam. Really going to look hard before scheduling on United next time!!!
RichardFlew with Hawaiian AirlinesLAX-ZIHMay 2025
Bring a pen. The airline insists that you fill out customs forms but do not have pens. How much could a pen that also advertises for Alaskan Airlines possibly cost in relation to the cost of the fare?
MargaretFlew with Hawaiian AirlinesBUR-SEAMay 2025
The delays we experienced on both flights to and from were cancelled or delayed which made for a very stressful trip. I would suggest monitoring the flight status continuously before arriving at the airport.

Staff were friendly and happy. Delta could make sure passengers that don't have the app know of changes. Without Kayak I would not have known about the change of gate or the delay. Kayak was faster to notify me.

They ended up paying for the bag twice, but the counter wouldn't take my baggage receipt. Left it to me to resolve. Not sure how to resolve the issue.

The customer service before board was very rude and when I expressed my concerns about making the connecting flight she laughed and told me I bought the wrong ticket. I explained once it showed the flight was delayed it no longer let me change seats or anything. I was trying to upgrade to make sure I would get to the next gate on time.

Non stop on long haul is the way to go. Great experience

The aircraft interior is old and tired on this aircraft. The entertainment system never worked despite the crews attempt to reset the system.

The flight used a B767 with a very old interior from before 2014. The entertainment system did not work at all during the flight despite attempts to reset the system. It was like they flew this route just to be competitive.

Old plane and old configuration/seats but still comfortable for a morning flight

They changed planes and the new plane couldn’t carry enough fuel to fly across the country so we had to stop in Kansas City to refuel. Flight was delayed .

Flight was too crowded and seats are too small, especially since passengrs are getting larger. Having a middle seat is ALWAYS tough! Woman on my left was large & kept creeping in to my space. Flight personnel were great! Have more savory rather than sweet snacks please.

Flight was crowded and the woman sitting on my left was large & kept crouching in to my space. You need bigger seats or smaller passengers to fit into the seats you DO have! Snack were OK. Would appreciate if airlines had more savory rather than sweet snacks, thank you!

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

The person I bought the ticket for didn’t make the flight.

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

After boarding the plane in Chicago, the passengers were told that there was a technical problem with the plane. Passengers remained on the plane as they tried to fix the problem. After what was probably an hour passengers were told that there was a need to change planes as the problem was not solved. Passengers disembarked and boarded another plane. After taxing to the runway and waiting for takeoff, passengers were told that owing to the thunderstorm the flight was unable to take off but would try and reroute. After some time passengers were told there wasn't enough fuel for the new route and the plane had to return to the gate for additional fuel. after another log delay the flight got underway. On the plane there was food, drinks, ice or entertainment. We were a glass of water, which appeared rationed. Flight arrived about 5 hours late. The pilot was fantastic and communicated with the passengers throughout the ordeal.

Same as last comment. Food sucks. Quality. Not surprising most people have no clue about nourishment Clearly

Not the fault of United—weather, reroute around weather, time sitting on tarmac, arrived couple hours late, too late for train into city necessitating a much pricier cab but weather…can’t be helped.

Friendly and professional flight crew. Aside from departure delay after boarding, easy flight and smooth landing.

Great smooth flight. Had a seating change, but that was an improvement. Thanks United Airways Crew.

Wish some foods provided rather than just biscuit/cookie for flight more than 2 hours

Wish a flight with more than 2 hours with some snack rather than just cookie/biscuit.

The flight attendant, a black woman with curly hair who sat near Row 21, was wonderful and kind.

It was good..clean, comfy seat. Friendly warm welcoming crew. Was able to check my cabin luggage at the gate which I was able to pickup in a decent time from baggage claim. The app gave all updates from delays to baggage claim info. Overall smooth flight.

Flight was delayed leaving Dallas. Arrived about 2 hours later than scheduled.

Flight delayed and missed connection. Rescheduled flight cancelled after 6 hrs wait. Rerouted thru ORD, flight cancelled, overnight stay in ORD. Still in the air on new flight!

We are too tired and frustrated to comment politely at this point

Terrible. Our luggage was delayed and couldn’t be delivered for several days. We got bad information from the airline agents at baggage claim. We had to pick up our car so we wouldn’t be charged for an extra day. We got lost in the maze of airport parking. The baggage claim agents didn’t offer us any compensation for our extra time and expense. We are tired, hungry and very frustrated.

The flight was flawless and we even arrived between 20 and 25 minutes early!

The only thing to like was that we eventually got to our destination

the plane was not full so the flight attendant had me move to an empty row which made for a good flight. The software for logging on and booking and confirming the flight is much too cumbersome.

Always comes in handy when I want a quick weekend getaway.

For the price I could have taken a “name brand” airline. No drink no snack and constant emails trying to get addition money for EVERYTHING other airlines include in the price. It looks cheaper but it’s Judy bait and switch and emails non stop!

The gate agents for spirit at EWR wouldn’t give me my ticket to board when I arrived 50 min from the flight, saying that I wouldn’t make my flight. They tried to reschedule me to arrive at my destination 14 hours after the original flight, which included a 10 hr layover in another city. I rebooked with another airline and it took me a total of 5 min to go through security. Then I see a charge on my card for a $100 change fee that I did not approve. Beware of this horrible place and these horrible people

Excessive fees for flight delays. What a Scam. I was not able to attend the wedding I needed to go.

Waited at the airport for over 4 hours to board this flight. Terrible airline

Was supposed to take off 8:00 last night. Got delayed till 8:00 this morning

It was terrible, we had to board and unboard the flight with a hour delay that caused me to miss an appointment and a surprise for my wife

When the flight ticket is expensive and you have to purchase check in luggage and there is no snacks, no entertainment, tight seats stuffed in the back of the plane not such good experience. I would like some to reach out to me . I paid for check luggage when I bought the ticket they made me pay again on the return flight extra $70. Very frustrating.

Excellent experience when I am looking for a budget airline where the main expectation is getting me from point A to point B with no frills.

Terrible. Flight cancelled with no reasoning and no flights to rebook. Employees were useless and did nothing to help. Did not even know where to retrieve luggage from the cancelled flight. Flyers beware.

No fault of Frontier staff: plane was very late, reached Orlando at 1 am, took a while to get luggage. Weather, gov financial shutdown impact on TSA, air controllers seemed to have multiple flights backed up. Frontier staff seemed to cope as gracefully as possible. It did reassure me that I and my new hip could adapt to travel challenges. Food/entertainment were irrelevant to my trip.

Terrible. The canceled my entire flight when I requested a refund for a trip frontier canceled trip one way.

Boarding was on time and plane departed as scheduled. There are obviously no amenities (food, drink, entertainment) on Frontier, but there also didn't seem to be any issues with luggage space either.

Inbound plane was on time and flight departed on time with no issues while boarding.

I knew going into this that Frontier, being a low cost carrier, would be pretty bare bones and charge for most extras but this was made up for by the fact that the airplane was a reasonably new Airbus, every employee was great and best of all, Everett Washington is an amazing airport - thanks Frontier for flying there!!!

i was unable to check in the flight. refund requested

It was well done. It was my first time flying with them and I was nervous b/c I have heard of many cancelled and/or delray flights. Everything went smoothly.

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.

The single worst check in experience I could imagine. I’ll never do any business with Frontier or any affiliated company
