Insights shared by verified travelers who flew from the United States to anywhere 
ChristineFlew with Alaska Airlines-Jul 2026
I am able to drop my bags off up to 4 hours prior to flight. This is a nice feature when I have an appointment that could run over a bit and timing could become an issue. I like to drop my bags off, then go to my appointments and not worry about getting to the airport within that perfect hour mark. The airport security line isn’t a time consuming process, so this alleviates worrying about getting to the airport to drop off rental and drop bags off prior to the hour mark. It gives a bit of flexibility and makes for a stress free travel day.
Verified travelerFlew with American Airlines-Aug 2026
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. I like to print the ticket because when going out of country or when luggage is delayed, you can hand the information over to the customs or baggage service agent.
KathrynFlew with American Airlines-Aug 2026
If you have a larger group that needs to stay together the concord coach line is more reliable, clean and cheap down to Portland or Boston for a busier airport. I’ll be avoiding small regional airports until my kids are old enough we can split the family for rebookings
Verified travelerFlew with Delta-Jul 2026
If you qualify for wheelchair assistance from gate to gate, don’t hesitate to take advantage of it. That was a lifesaver since they know their way around and have the latest gate info. They are in contact with gate agents who are expecting you.
AndrewFlew with Southwest-Aug 2026
Rochester airport is a gem. Excellent for a place to work and plug in away from crowds. So if you need to get some work done before flying, you will be able to do it at Rochester's airport.
ShashankFlew with Delta-Jun 2026
Fairbanks airport is rather small with one terminal so it is very easy to navigate the gates and tsa. We were able to get from ticketing to tsa to gate in less than 30 minutes

JFK was a convenient airport to fly out of if you arrive for an early flight. Download all your media ahead of time. don't buy the internet in-flight if you don't have to.

Be prepared to wait if there's any weather going on at either airport. Bring a book and snacks! You'll need them! Also, airport charges like $10-13 for a pb&j!!! Bring your food.

American Airlines was pretty convenient and efficient. My recommendation would be to get a good amount of time to get situated at your terminal in case of any last-minute issues.
NicoleFlew with Delta-Jun 2026
Terminal has great options for food. Lots of seating and charging stations. If checking luggage and already paid online just drop them at the curbside and continue to the check point.

Pack healthy snacks. When a 2 hour flight turns into over 7 hours, mini servings of pretzels or cookies doesn’t cut it.

LaneFlew with Delta-Jul 2026
When you are booking with Delta make sure you look at the features of each aircraft. Most Delta mainline planes have seatback screens and free WiFi, but they do have a couple aircraft you want to avoid if you would like these things. The smaller regional aircraft EMB-170/175 the CRJ 200, CRJ700, and CRJ900 do not have screens and sometimes they are not internet equipped. The only Delta mainline aircraft that doesn’t have seatback screens is the Boeing 717-200, but they usually have internet unless it’s not working. They also don’t have consistency in their first/business class product. It varies greatly, even among some of the same aircraft types so make sure you do your research before committing.’ To specific flights.
Verified travelerFlew with Delta-Jul 2026
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. Not as many food options, and not many healthy food options, as it would appear along concourse A.
ChristinaFlew with Allegiant Air-Jun 2026
The “Allegiant air only” airports are bare bones. They are packed. There’s no lounge. You want all that stuff you better fly a major carrier and accept at least one connection and pick a different Florida airport. But you don’t have to arrive a million hours before your flight so it’s almost like your house is the lounge.
Verified travelerFlew with Lufthansa-Jul 2026
Our gate at terminal J was very crowded and seating is extremely limited. Security check was quick and smooth. They only ask to remove laptops and tablets. Liquids can remain in your carry-on if you don't check them. As usual, allow plenty of time to get through bag check and security - 3 hours like they recommend.
Verified travelerFlew with Delta-Jul 2026
Find the speakeasy in Denver International concourse A and put your name on their waitlist. If you are going to any of the lounges, reserve ahead or immediately get on their waitlist. I was 50th on the wait list by the time I went from rebooking to trying to go into the Capital One Lounge.
LisaFlew with Allegiant Air-Jul 2026
Pack plenty of snacks, fill your water bottles pre-flight, bring in flight entertainment (book or download a game you can play on your phone) and order the aisle seat for additional leg room for comfort. There is no complimentary snack or beverage options, no in flight entertainment options, and the seats do not recline.
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.
Verified travelerFlew with Delta-Jun 2026
Take photos of luggage (if you care about it) prior to boarding. Also, report issues at destination airport and not after leaving. Unfortunately i let my fiance handle gathering our luggage and didnt take note of the damage until we were back at home the morning following our return.
SarahFlew with Delta-Jun 2026
Delta had a very organized boarding process which I appreciated. The construction on the way to JFK meant my Uber had to detour through some residential areas which was annoying. I would have used the subway and AirTrain if I hadn't been traveling with my cat.
MariaFlew with Alaska Airlines-Jul 2026
I dont think any of local airlines now offering food for flying under 4 hours, so if you fly with kids or during your lunch/dinner time. Pack your own food or you will only get tiny bag of pretzels or peas during your trip.
CourtneyFlew with Delta-Jul 2026
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.
Verified travelerFlew with Alaska Airlines-Jun 2026
Check your flight the night before! My flight was canceled and rebooked but it is a common thing to have flights cancelled. The airport is small so going through TSA is fairly quick.
JulianFlew with Delta-Jun 2026
Be prepared for new screening processes including dog sniffing. You're asked to walk in group of 2 for about a 15 foot stretch while a sniffing dog follows just behind.
WaymonFlew with United Airlines-Jul 2026
Always select seats in 'A' aisle and remember overhead storage is extremely small which required gate checking bags if your carry on is med to large. (Ref to United Airlines.)

Pay a little more and go with American or United. Also, fly earlier in the day. It seems that night flights have the crankiest crews on Southwest.

Seattle is a huge complicated airport. Allow time to change gates if your passing through. And to get thru TSA and to your gate can take time

Turkish airlines was very generous in baggage allowances. You do have to pay attention to the weight limits, but we were allowed a personal item, a carry-on, and two checked bags per person.

My main tip is to allow a bit of extra time at SFO, since the airport is currently undergoing renovations. It is nothing unmanageable, but giving yourself a little buffer can help avoid delays.

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.

OlgaFlew with JetBlue-May 2026
Here’s the part that confused me the most. JetBlue flies only from terminal 5. Delta (at least) arrives in terminal 4. Be aware that there is a lot of walking to get out of terminal 4, then you board the sky train, then you walk more, and finally get to terminal 5. There, surprise! You have to go through security again. At JFK, some security lines are ridiculously long and slow. It’s very annoying that transit passengers must go through that again when moving between terminals. One more thing related to terminal 5 where JetBlue flies - there is absolutely nowhere to sit and almost nothing to eat before going through security. The security lines were better organized though and it didn’t take that long.
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 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.

Flight left on time and was early landing. Seats not comfortable and not enough space…

Flight left on time and was early landing. Seats not comfortable and not enough space…

Flight left on time. Seat spacing is way too small…

It would have been better if the flight was on time

Fairly good - the seats seemed more comfortable on this flight. The staff out of Detroit were quite friendly. But they directed us to the wrong carousel for luggage. :(

Just crazy with times being pushed and pushed and pushed and gate crew at Philly super rude and unprofessional with many under stress with delays.

I liked the new boarding process. I thought the buyup options (legroom, early boarding) to be easy to request and reasonably priced. All the Southwest team from gate to in-flight were so nice.

Flight time kept changing and so did the gate. It was very frustrating

Exceptional. The gate crew responded quickly and got me onto this earlier flight as the final passenger, saving me more than four hours of wait time for my reserved flight.

The flight was delayed due to earlier issues at other airports. The crew was excellent & made it a good trip.

Boarding process of asking for volunteers to check bags goes against the system you had before with 2 bags checked free. This process is more of a guilt trip than a caring attitude toward the customer. In addition bag-size scrutiny has increased which also slows down the process of boarding. My wife said she will not fly on your airline again unless there is no other option.

One of the restrooms didn’t work. The ones that did never got replenished. Flight attendant just sitting there on their phone. No notification that the bathroom was broken so long lines. Apathetic crew.

Pushing back flight and ultimately cancelling it after multiple changes and hours of delays. Comm were terrible as to what was going on and what options were available.

Even though we arrived early and checked in, for some unexplained reason, our bags were removed from the plane and put on the next flight. It took over 12 hours after arriving to get our bags.

Stewardess was not accommodating when I requested a second drink.

The morning calzone was less than impressive and we ended up with heartburn

Some of the passengers are coming on board with luggage so overstuffed and/or too large that have no business going into the overhead bins.

I am in a wheelchair The gate agent knew exactly how to boarding A wheelchair first also the flight attendant knew exactly what she was doing

There is consistently no communication/updated time slots in the app on when a flight will board when its delayed, which is the most frustrating as a consumer trying to understand if they need to get food now, or if there is actually a chance for them to eat during their layover. This keeps being my experience with delta and a potential reason to change airlines.

Long delays at both DCA and MSP; Crew did not keep us informed (or very little). Airplane was showing signs of heavy use (not up to Delta standards). Food options for Business Class have dropped in quality. After landing we sat on tarmac for maybe 25 minutes with no provided chance to use the bathroom and crew did not tell us what was going on or give an estimated time to expect to be at a gate.

Both of my flights to and from JFK experienced significant delays. Most notably, my first flight was delayed by six hours due to crew members being affected by delays on a previous flight. While I understand that disruptions can occur, Delta’s staffing and operational planning should include sufficient contingency measures to handle situations like this rather than placing the full burden of those delays on customers. Additionally, the $12 meal voucher offered as compensation was inadequate, particularly given the high cost of food and beverages at the airport. Considering the length of the delay and the substantial inconvenience caused, I believe more meaningful compensation would have been appropriate.

This flight has a history of leaving late, however, I was pleasantly surprised that it was not delayed this day. The flight went smooth, except I was in a window seat and the wall and my feet were freezing. I found it difficult to sleep due to being so cold, I also was using 2 provided UAL blankets and could not get my feet warm. This was annoying, but I still made it there on time and safe.

Staff didn't seem confident about the ingredients in my lactose intolerance meal

the seat has a problem. the back had a hole.

The back to back mechanical delays from Denver to San Diego and then on my return flight from Denver to Great Falls it added extra time both ways

Really old place. Not as clean as it should be, tray tables needed better cleaning. The items, trays and some other items need to b6 engineered. Anything task you or crew may do is incredibly load, seriously engineer for quiet smooth, easy. Just opening and closing the tray table is actually dangerous and can easily injure a finger. I'm sure it happens as it happened to me! First time I used United and likely will be the last!

Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

Flight was 2.5 late. Maybe not United’s fault but late none the less. We were late as well on the first leg. WiFi quit working with an hour left.

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.

The flight to America was freezing. The overnight flight back to the UK was boiling hot and the cabin stank of toilet or occasionally perfume, even though I was several rows back from either bathroom. Food was tiny portions. Two small pieces of tough and dry beef in random gravy with pretend mashed potato raking up most of it. Very little veg. Salad was ok. Wooden cutlery broke within minutes of using. Lots of old films for entertainment. Some new ones. Generally a bit rubbish.

It was a good experience, unfortunately my checked baggages were come late and not arrived on time.

Flying on this airline is nothing short of a full blown circus clown show. On a recent return from my mother’s funeral, my only available choice from IND to PWM was American, which I hesitantly booked as I rarely fly them for many of the following reasons and never will again. I was booked IND-PHL-PWM totaling about six hours. The flight was cancelled due to NE weather. They rebooked me on a two stop flight IND-DFW (Yes DALLAS)-PHL-PWM, still all on the same day. After arriving in DFW, they continually delayed the DFW-PHL flight due to maintenance issues on the arriving flight. Finally it was delayed to the point that my PHL-PWM connection was no longer possible. They then rebooked me thru LGA with the short flight the NEXT DAY to PWM and offered to put me up for the night in NYC (or so I assumed). The flight DFW-LGA was then delayed so much that I asked to be put in an earlier flight with a lessor delay. Throughout this day chats with their AI assistant were useless as were subsequent chats supposedly with a real person(?). Only one customer service agent in DFW was actually helpful and appeared to care. Upon arrival at LGA post midnight, they issued me car and hotel vouchers in Trenton NEW JERSEY at a very old Howard Johnsons ONE HALF HOUR from LGA. The hotel was an $85, 1.5 rated hotel in a very sketchy area of NJ that I would have never voluntarily booked. As I prepared to catch the car back to LGA the next morning I received a text that my flight was cancelled. TWICE IN TWO DAYS. I went to LGA hoping to have AA book me on an earlier Delta flight. The full service line was at least 200 people deep, so I tried to reach a real person agent by phone. After 1/2 hours on hold I gave up and waited for my later LGA-PWM flight. It actually started boarding on-time, but only shortly after announced a maintenance hold. We were told it was nothing serious, just an adjustment to the Captains seat. Only one update was given while we waited 1.5+ hours for a “SEAT ADJUSTMENT”. Can’t forget to mention that on all of these planes the WiFi only worked on two. During that time at least three others flights in my area announced that they were overbooked and were taking volunteers before bumping people. Another flight to ORD announced a gate change and less than five minutes after announced that they were really not changing and announced for everyone to return to that gate. Can’t forget to mention that on all of these planes the WiFi only worked on two.🤡🤡

Paid for wifi but it didn't work once. Seats were incredibly cramped and passengers sitting in front was reclined the entire time and staff did nothing

Delays and cancellations. Mechanics weren’t on site. Replacement plane took hours to arrive although it should have arrived within 90 minutes. Flight back was cancelled. Ended up driving over 12 hours and wasting 3 days between everything.

Flight was delayed multiple times and rerouted to different concourses in the airport because of all of American's delays. App/boarding pass would not update with changed gate information.

Absolutely infuriating. I was flying standby to get home earlier after flying 4 times with American in 6 days. I was #2 on the list with seats near the front and middle, in addition to the 4 first class upgrade seats that came back into the pool. I am a Platinum member, have their card, and they put me in the 2nd to last row in the middle. No loyalty whatsoever and they lost a fan for life. There is reason people have negative comments about American and I am done supporting them.

Horrible - their gate agents do not care and loyalty means nothing to them. Planes are often late and you are left on your own. Oh, and WiFi - good luck!

Awful! We boarded and then sat on the plane for 50 mins before having to deplane due to a maintenance issue which should have been addressed before boarding. Then we had to change terminals as there was no other plane for us at the current terminal. Then we waited another 2 and a half hours to board again only to wait for 50 mins on the plane again for the snacks to be brought from the broken plane. And once we were on the flight we still only got the complimentary cookie and soda or water. No food vouchers provided even though we had waited over 3 hours for our flight.

There was a 6 hours delay in our departure. And yet, no compensation was offered. A company should be responsible for such a delay.

Little bit of trouble getting my KTN and pre-check status onto the ticket, but otherwise the counter staff were friendly and truly concerned to get it right.

Plane was delayed for 3 hours, due to situation within aa control. Information was shared poorly. We sat on tarmac for over 40 minutes after the 3 hour delay.

I know Frontier is a “no-frills” airline. I understand the concept. However, I jumped on some tickets for our family vacation, expecting to play a bit of a game to figure out the family bags and not over spend. In the end, I got the short end of this deal by far. 1. I did not expect them to charge the baggage fee for each direction. It makes the fee look high-ish at a glance, but reasonable. Then when you get to checkout and realize you have to pay it twice to come home with your luggage, it becomes ridiculous. 2. The low checked bag weight limit. I am used to packing a 50lb bag with my preferred airline. Frontier’s artificially low 40lb limit more quickly triggers the extra weight fee, which almost DOUBLES the price of the bag if you go over ($79 for the bag/$75 for the next 10 lbs) 3. The fee for a carry-on bag is the same as a checked bag but with a lower size and weight limit. Make it make sense! 4. The seats are terrible. My 2.5 hour flight almost had me losing my mind. I’m 6’3” and my femurs barely fit in the space provided. My knees had to wiggle just right to jam into the crack next to the armrest of the seat in front of me. The cushioning was thin and inadequate. I am tall but I’m not a freak. These seats are unacceptable. 5. I overheard the woman next to me speaking with the gate agent about being charged a $25 fee for not checking in online - she checked in at the airport counter when she arrived. That’s ridiculous. She was old and in a wheelchair. She had a paper boarding pass, and was obviously not tech savvy. She should not be punished for that. 6. They do not have good placement in the terminals. It was always out on the end or down on a subfloor, and we had to walk out on the tarmac almost every time. In Denver. Their home airport! 7. Every time I loaded a new page on the website while buying my tickets or my bags, it was constantly trying to upsell me on some esoteric bundle. Like, a pop-up every time. Very annoying. 8. No screens in the boarding area (at least where we were) to confirm you’re in the right place. Just static gate number signs. I am sure these are standard practices for Frontier, and I should have read more about them before I purchased tickets, but as a result of this single round trip, I do not plan to ever use this cut-rate airline again. I would rather pay the normal amount for a ticket and be treated like a customer instead of a mark.

Our flight was delayed 2 hours and when they changed the the time to 1 hour I wasn't alerted and when I checked the gate the plane was still there but they already shut the doors so I had to buy another flight.

Great except upon arrival it took them a long time to open the doors

Frontier feels like a family I Worked for Eastern Airlines back in the day and I felt the family vibe that I had then. Thank you

Terrible. Delayed my family flight for several hours affecting family plans

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.

Tiny seats, no entertainment, no amenities, delays, they charge for carry on and their allowed personal item is smaller than in other airlines.

The seats are tiny and they don’t recline. The planes are dirty and very small. You have to pay for carry on and even the personal item that you’re allowed is smaller than with other airlines. Flights are usually delayed and there’s no screens or any amenities or entertainment.

Flight was delayed but it was very smooth. Crew was very nice. Seats are uncomfortable but ok.

Flight was delayed and then my second leg was completely canceled. Had to get a refund
