Insights shared by verified travelers who flew from the United States to anywhere 
JacobFlew with Breeze Airways-Oct 2026
Whether you're flying out of Arcata California, Las Vegas, or Provo Utah, I recommend flying with Breeze Airways. If your trip allows, go with one carry on and pay for that carry on 12-24 hours before your flight while you're checking in on their website, not when you book the flight weeks before. It's super easy and you get the best discount this way ($45 instead of $50-$75 when you're at the airport or if you try adding the baggage while booking your flight through a third-party).
CarolFlew with Japan Airlines-Nov 2026
JAL has a 2 bags free policy per person which is nice. Minimum economy + ticket or higher is best for a long flight, 12 hours. You have a designated line for check in, lounge benefits and better seats. Make sure you do immigration and declaration on-line before your trip to make it easier to go through customs.
EricFlew with United Airlines-Oct 2026
Air Canada will courtesy check cabin bags thru the final destination for free. They generally offer but if not just ask with a smile. It saves them the hassle and delay due to too many cabin bags and not enough overhead storage. Pack accordingly - no lithium batteries, etc. Use you personal item carryon for that.
CliffordFlew with American Airlines-Sep 2026
Download any media content prior to your trip, take a tablet for a bigger screen, and take some ibuprofen or Tylenol prior to boarding so your butt and back will not be sore from the very stiff slimline seats.

This flight usually departs from gate B28. Enjoy a quick meal at Legal’s or Stephanie’s, refill your water bottle at the water station nearby, and enjoy the very quick boarding process implemented!

Try to fly as early in the day as possible. Delays compound as the day progresses. I always try for a flight where the plane arrives the previous night.
JuneFlew with Alaska Airlines-Nov 2026
If there is a significant delay, talk to the counter asap and ask if it's possible to switch flights to a one that is less delayed
PAULFlew with Southwest-Oct 2026

JerryFlew with United Airlines-Sep 2026
Always watch the flight connection window. If it is less than an hour and changing concourses (like Dulles), you're asking for trouble (have your travel insurance contact number ready). Of course, that doesn't apply to American or United Airlines as they are typically late. If you get an Embraer 175 or larger aircraft, you will have a great flight. If longer than two hour flight, hope you don't get a Boeing 757 aircraft - the most ungodly uncomfortable sardine can with wings, ever made. Have a chiropractor or massage specialist waiting at your destination. If you have a 757 for Trans-Atlantic or Trans-Pacific flights, choose business class seats.
Verified travelerFlew with American Airlines-Sep 2026
They boarded us as usual, but then we had to wait on the plane for a long time until for some reason they had to switch flying crew. The plane was newer, so the seats were semi comfortable in economy class and everything was working. One good thing the crew on the plane asked people to stay in their seats and let people with connecting flight to go first as they were getting late for connecting flights to go further on their destination.
Verified travelerFlew with United Airlines-Oct 2026
Check your watch carefully! I was afraid I was going to be late for my flight because I thought my watch said it was an hour later than it actually was. Also, if you need special services, like a wheelchair ride between flights, be sure you make it at the same time you make your reservation and get a confirmation for it.
AnneFlew with Alaska Airlines-Oct 2026
Can upgrade from Basic(no change, no refund) to changeable ticket for $100 more -BUT then you must pay another $75 to reserve that new seat PLUS any difference in airfare. Not as great for changing flights as for cancel & rebook using credit received for original booking.
ChipFlew with Cape Air-Sep 2026
Since we live on an island, we try to arrange for a Plan B when making travel plans. There are two ways to ‘escape’: ferry or flight. The available flights on Cape Air, Jet Blue and United are scant, so plan accordingly.

TSA had passengers at SEA-TAC shuffling a long distance between screening locations when one got backed up, but otherwise it was a smooth dropoff, check-in, shuttle to terminal experience.

Be sure to dress warm & have plenty of cushion on your bottom. The seat of the economy class is not that comfortable. If you can afford to upgrade, get better class.

Be prepared for full flights, check in as process has changed on seats, check in early as boarding has changed to groups now. if you can reserve your seat early
NicholFlew with United Airlines-Oct 2026
Ensure you leave yourself enough time at the airport. It is a busy airport so can take a little bit to get through security if you don't have TSA precheck.

Seattle is a large, confusing, multi gate airport. Various modes of access to gates is not always clear. Prepare for delayed flights as flight turnovers are high.

RonaldFlew with Delta-Oct 2026
ITimely information could have changed our plans. We learned only after waiting about 40 minutes that an earlier ground stop had delayed flights. Had we been told sooner, we might have changed our flight, delayed our trip to the airport, used another airport, or— in my case—left a day earlier. Sharing the information only after those options were no longer practical left us feeling stuck with a bad situation. Recommendation: Notify passengers as soon as a ground stop or other significant disruption is known, and provide clear updates about expected delays and available rebooking options. Before traveling, passengers should also check for airport and airline alerts and consider early flights, which may offer more flexibility when disruptions occur.
KimberlyFlew with Delta-Oct 2026
Make sure you have over an hour at least to make flight. I had terrible problems trying to get my precheck TSA on my tickets and ended up waiting over thirty minutes going thru regular TSA line, while my husband walked right through. Two different Delta employees tried to help, and they still couldn’t fix it. I was very disappointed.
BenFlew with Austrian Airlines-Sep 2026
Be prepared for a prolonged journey from the new car rental center to the terminal. Shuttle buses are a mess, it takes a long time to get on one and they don’t take you directly to the part of the terminal you need. Also LAX still has old on-board luggage scanners which means no liquids in carry-ons.
PaulFlew with American Airlines-Oct 2026
That you don't get much help making connections to a domestic flight after an international flight in Philadelphia. At least that was our experience. Get assurance your bags have been loaded. Or bring a carry on bag rather than book your luggage. Maybe Philadelphia is just a confusing airport, I don't know, but most trouble we've ever had.
Verified travelerFlew with Alaska Airlines-Oct 2026
Make sure you bring a fillable water bottle as often turbulence makes in flight drinks or snacks unlikely. Plan on delays and don’t expect any kind of exemplary service. I would love to say it’s a fluke but my last 4 flights have been the same. Mediocre to worse is about all you can expect.

Even though Tulsa is usually not busy, it is better to pre-check in online to get your travel and award numbers into the system. You can always go to the counter agent.

Check a map and take the train between gates. Signage is terrible. Detroit has allowed restaurants and boarding to spill out into the concourse, so can be a recurring narrow struggle through crowds walking between gates. If you see food you want, get it.

Delta, Delta, Delta. JFK has first priority to NYC's airspace, so if weather is dicey, go out of there versus LGA. Due to limited airspace, LGA is more likely to cancel flights which is outside of Delta or other airlines' control.

Terrible, decided to delay our flight since another flight require a flight captain

staff and crew were great but the flight delays for the last few flights are insane. After a long day of work and you will get a notification of flights delay is not the message we want to see. And for some reason it keeps happening often this year.

I love southwest. I can not wait until all the planes convert to the upgraded planes. I love the charging option and the newer seats. Thank you from a very loyal Southwest customer.

My return flight was much better than the flight there! I paid for seat to Veagas but not the return. Thankgoodness they assigned me a seat with additional leg room as I have back and leg problems. I really appreciate it. With the flight already being super expensive due to gas prices and having to pay for bags (now) I needed to save some money.

My first flight from LGA to STL was not good. They didn't do service until over halfway through the flight, the internet didn't really work, and the crew all seemed like they didn't want to be there.

We were stressed about landing as our connecting flight was about to start boarding, being unfamiliar with the airport or where the gates were. We exited the plane to discover we were at the gate we needed. We would be getting back on the same plane but nobody told us we could have just stayed onboard. My wife and I were seated on aisle seats across from each other. We asked if there was a way we could sit together. Once we were at cruising altitude they let us move to an unoccupied row so that was nice.

It’s Southwest. The seats are small, the snacks are meh, it’s $50 to check a bag. It’s exactly fine. Could have been better. Could have been worse. It’s not Spirit

They delayed my flight all day but didn't try to reschedule me until all other options were gone. Ended up on a red eye. Not happy. Lesson learned, don't book the last flight from SJC to RDU.

Every single flight I take with southwest is delayed by at least one hour. Unbelievable

When I made my reservation it would have been nice if kayak would have included my luggage. Unaware that I had to pay $45 each way. Should have asked at reservation time if luggage was being checked

My experience with Delta is always pleasant. My return flight #1426 from ATL to RIC was very delayed with departure and landing. It also took a substantial amount of time for baggage claim. It was already late at night, so the delays made for a very long day. I did not get home until after 12 midnight.

I had a great flight with delta. Plane was clean and the staff was nice, I would fly again with delta.

After flying with Qatar Airways and Kenya Airlines. Delta leaves a lot to be desired

A 6hr delay is going to put a damper on all reviews. It was almost impossible to get into the Delta club also. Zero conveyance. I could not use my status for anything. Makes me wonder why am I loyal to delta?

I fly coach so there is always the feeling everyone up front has more space than me. Everything was fine - on time which is the most important thing!

Great overall experience and use of the Delta One lounge was amazing!

I used by Skymiles to upgrade to First so that I could comfortably work using my laptop. But WiFi was intermittent and unavailable for long periods. I feel like I wasted 70,000 miles :(

Great as one can be for a one connection 6 hour flight

Packed flight and not sure why dinner service would start at midnight while passengers we’re trying to sleep

The gate attendant was not clear w message on flight delays.

Very uncomfortable and cramped seats. Everything else was okay, the crew members were nice but nothing was exceptional.

Check in went smoothly. Flight attendant who was assigned my area barely paid any attention to me! She acted as though she was extremely busy and flustered. Maybe she was new?! I told her to change the language on my screen, she said she’d come back to help me but never did so I was able to solve the problem on my own. She came back and said she’d made adjustments on her end. Highly doubt it because I found the setting to change the language! Also, I noticed everyone was eating before we landed so I pushed my help button and she never came so I got up to find her to ask her if I can have breakfast. She said they are not serving breakfast but I can have a sandwich. Yes, that was her response as I saw everyone eating breakfast!!!

United staff were very communicative, the new starlink Wifi is amazing as I was able to work easily.

Starlink internet made the flight time shrink and I was able to work.

Tiny seat made for midgets. You can’t put a normal size human in such a tiny seat for 8 god damn hours! Hot plane, no air. Lost bags at Rome airport for 8 hours, lucky to have found them. Horrible flying experience, United Airlines should be embarrassed!

The issue is the flight is delayed, which causes me Missing the connecting flight by 3 mins. Remember the connecting flight is a US codeshare flight so UA should be able to inform the operating airline about the delay.

Seats are made for children. An 8 hour flight with tiny seats is more like a cattle car. Lost bags at Rome airport caused a 7 hour delay.

We sat on the tarmac in Denver for over 30 minutes because a plane was in our gate. The pilot kept saying it will just be 5 minutes or less. However, we sat for over 30 minutes. Experiences like this make customers not trust what the pilot is saying.

Waited on tarmac for approximately 15-25 minutes before taking off. When landing, the time it took to taxi to our gate was the also 15-25 minutes.

Waited on tarmac to take off for approximately 15-25 minutes. When landing, the taxi to our gate took a similar amount of time. This happened on both of my United flights.

I have generally had positive experiences with American Airlines (outside a handful of delayed flights), which is why I wanted to share this feedback constructively. On my recent flight, my travel experience was extremely uncomfortable because my seat mate significantly encroached into my assigned seat space for the duration of the flight. As a result, I was forced to sit partially sideways, with much of my shoulder and upper body extending into the aisle. Unfortunately, my back still hurts from maintaining that awkward position.I recognize that this is a sensitive and challenging issue for airlines and cabin crews to address. Everyone deserves to travel with dignity and respect, and I understand that individual circumstances can vary. However, fairness also requires that all passengers have reasonable access to the seat space they have paid for. When one passenger's use of space substantially impacts another passenger's ability to sit safely and comfortably, there should be a practical solution available.I appreciate the complexities involved, but I hope American Airlines will continue exploring ways to ensure that all passengers can travel comfortably and equitably. This experience detracted significantly from what should have been a routine flight.

The crew was great! The issue for me is the aircraft. The Airbus A32x is just not comfortable enough and the entertainment delivery via personal devices is problematic.

The crew was dis respectful even in business class. I will not recommend AA to anyone and will also fly only when there is no choice

Three aircraft in succession experienced maintenance issues, resulting in a six-hour delay. The original aircraft required replacement, and the substitute aircraft arrived more than two hours late. Passengers boarded that aircraft, only to be told later to deplane due to maintenance concerns. We then boarded a different aircraft that had arrived at the gate, only to be instructed to deplane once again because it, too, experienced maintenance issues. After hours of delays and two separate boarding and deplaning events, passengers were directed to a third aircraft departing from a different terminal and had to rush across the airport to make that flight. That was the only aircraft that ultimately departed without incident. Of course, passenger safety must come first, and I am grateful these issues were identified before takeoff. However, when three aircraft in succession require maintenance attention and passengers are repeatedly boarded before those issues are discovered, it raises legitimate concerns about American Airlines' preventive maintenance procedures and aircraft readiness checks. One aircraft with an unexpected issue can happen. Three aircraft in a row, combined with multiple boarding and deplaning events, suggests a pattern that warrants review. American Airlines needs to take a hard look at both its maintenance practices and its decision-making process for boarding passengers before determining that an aircraft is ready for service.

Overall, it was a good experience, although the boarding process was somewhat disorganized, with no clear signage or designated areas indicating where passengers in different boarding groups should line up. Additionally, the seats felt quite outdated and could benefit from modernization. While the cabin crew provided good service, the experience lacked the personalized attention I would have expected.

New internet speed is awesome! Great flight and staff. Also most efficient and fast baggage handling ever in Philly!

The wifi was broken. The temperature on the plane was quite warm, and my air vent didn't seem to blow anything but warm air. The flight attendants were nice.

This flight left LAX on time and arrived early in HNL. The flight crew was excellent, no issues with service or attentiveness. My issue is with the A321neo ... First class should be renamed business class as the seats are not that comfortable. And, having to use my phone as the entertainment device is just not acceptable ... I'm not going to carry a tablet so I can watch a movie. The music choices are limited, at least IMO.

Seats are getting smaller and smaller. In flight movies are poor compared to other airlines. Food is mediocre.

There was a 4 hour delay, some of which was attributed to ATC weather but started with maintenance and then later also log books. Though the flight went far beyond the scheduled time, there were no accommodations such as additional meal options or anything else.

Airport staff was terrible, they made up excusses on how I can get to my terminal, I missed my flight then had to pay for A whole other flight! Worst experience ever, even A employee also loughed and said yea sorry for our poor training.

THE BARE METAL SEATS AT THE FRONTIER GATE IN CLEVELAND HOPKINS AIRPORT ARE DISGUSTING...BUT JUST A LITTLE BETTER THAN THE SEAT MATERIALS ON THE PLANE! THE "COMMERCIAL" ANNOUNCMENT PUSHING THE CREDIT CARD DEAL IS OBNOXIOUS AND UNWELCOME! THE VOLUME OF THE OFFER ANNOUNCMENET BLARES LOUDLY AND IS FILLED WITH A HYPED UP, CANNED SCRIPT. BOTTOM LINE IS THE FLIGHT AND THE CREW WERE VERY GOOD EXCEPT FOR THE ABOVE.

Maximizing profits is one way to a healthy bottom line, the other is repeat business and referrals from satisfied customers. Frontier has clearly chosen the former. One of many examples: Family emergency required me to cut trip short. Headed to the airport to fly standby for the return trip I had already paid for (yes I understand prices vary with demand etc). Was told there is no standby and that I would need to pay for, despite what it's called by the company, what amounts to a new ticket. And surprise surprise, there turned out to be dozens of empty seats on that flight. To say nothing of the sleazy third and fourth party resellers, the flight/ticket insurance I elected and thought I had paid for that mysteriously wasn't there when I needed it before I left, and on and on with third world sleazy management decisions. The inflight coffee (that I had to pay for) was very good though.

You have to be super careful when purchasing as *everything*, a carryon or a sip of soda, has a fee. They relentlessly chip away at you with surcharges and extra costs … and it’s not always clear what you are getting when you buy your ticket. Will not fly them again. And … crew were not friendly until off boarding .. like they don’t like working for Frontier.

Air was off while waiting on the runway and the temperatures became very uncomfortably hot. Flight attendants were very loud and rude the entire flight.

I booked tickets from San Diego to Cincinnati months in advance to attend my sister’s wedding, a wedding where I was serving as the officiant. At 10:00 PM the night before my 6:00 AM flight (just 8 hours before departure), I received an alert that my first leg to Denver was delayed, causing me to miss my connecting flight to Cincinnati. When I called Frontier customer service, they informed me that they couldn't get me on any other flight that would get me there in time for the Saturday wedding, let alone the rehearsal dinner. Because I had a critical role in the wedding, I was forced to buy a last-minute ticket on another airline for three times the original price, costing me well over $1,000 extra. Even with the emergency flight, I still missed the rehearsal dinner entirely. When I spoke with Frontier, they agreed to refund my original ticket, but showed zero care or accountability for the massive financial burden and distress they caused. Their "compensation" for causing me to spend an extra $1,000+ and miss an irreplaceable family event? A $75 Frontier voucher. Frontier completely dropped the ball. Their customer service showed zero empathy, and their reliability is non-existent. I will never fly Frontier again, and no one else should either if they actually need to get where they want to go. Tip for anyone flying from Denver to Cincinnati: Avoid Frontier connecting flights or layovers at all costs, especially for time-sensitive events. Book direct flights with an airline that actually offers reliable customer support and rebooking options when delays occur.

Their customer service showed zero empathy letting me know that it was Frontier who was the real victim by refunding my ticket price, and their reliability is non-existent. I will never fly Frontier again, and I strongly advise anyone who actually needs to arrive at their destination on time for an important event to book with literally any other airline.

Flight delayed and missed connection. Next available flight was a 10 hour delay.

It got me to my destination? However we were an hour delayed departing, and we never received any updates or notifications from staff. Poor communication and customer service.

Frontier didn’t give us enough notice that our flight had been delayed. I was just entering the airport when I received the notice, less than 2hrs before my scheduled flight. They delayed it 1hr 22min because another jet left late out of Vegas. Frontier needs better communication with customers because I could have eaten at home and had someone drive me instead of paying for an Uber.
