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.

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

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.

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.
MaryFlew with Delta-Aug 2026
Nashville signage directions could be more clear: Do you need a flight ticket > go here. Do you need to check in luggage > go here. Have you already checked-in >go here to security/TSA.
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.

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.

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.)

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

It made me scan with my phone to check in, but I couldn’t figure out how to do it and then an employer was there pushed buttons on the kiosk and printed up a boarding pass. Where did customer service go?! and then, we had to wait in a huge long long long line just to drop off the bag. Be certain you give yourself extra time for all of this chaos. Flying is getting worse and worse every time I fly.

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.

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.

Airline reviews

Seated at front bulkhead for a smidge extra leg room away from home and on flight back home. Away crew was very proactive about assuring our carryons had space close behind us (because no seat in front of us our personal items had to be in a small bin overhead). They actively required passengers place overhead luggage on its side so more items could fit in bins. Home crew made no such efforts. I had to struggle back rows to get overhead bags upon landing, no crew help then either, and some disgruntled passengers as I and others retrieved our bags. There was a system that worked pretty well. The home bound crew just didn't feel like working.

Southwest has inacted unfriendly customer policies like other airlines. Watch the fine print very carefully if you are having to alter flight arrangements. Rules are now complicated and very stilted to travelers sacrificing travel funds (unlike before where the simple, straight forward flight change policy was worth the extra premium for ticket price.) On the positive side, SW Flight crews are still wonderfully helpful.

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.

They announced a mechanical issue prior to boarding Said it was fixed, we boarded Waited Then learned it was not fixed Had to deplane and go to new gate Bought wifi on plane and it never worked

The plane was a rather tired 737-800, with old style small luggage bins. Poor air flow. USB charger in the infotainment system was not functioning. The flight was 2 hours late due to crew rest requirements (not their fault). On arrival in Seattle, waited on the tarmac for 30 minutes with very few updates from the crew.

Flight was delayed and we were on the runway after landing for 30 mins

The plane is old. There was water dripping fown from the air cooling system. The toilets were mot that clean

We were delayed so pilots can rest and had no WiFi the whole trip. First class seats are small compared to other planes

The experience was bad. Flight was delayed to handle maintenance (understandable) but still there was some dew forming and dropping as droplets on few seats. Internet at best was allowing some browsing but at a snail pace.

We were delayed 2 hours because of a broken seat. Other than that it was a very nice flight.

There needs to be better accommodations for waiting passengers. A a designated standing space that is separated and away from concourse traffic.

My seats are comfortable because I choose to fly in the exit rows and this time upgraded to first class with minimum sky miles. Otherwise, I would not be happy in regular seats or even middle comfort seats. Onboarding on the return flight from Nashville to Atlanta was hot and very uncomfortable for over 30 minutes due to extreme hot weather. However, Delta should provide some other air flow option as it was almost unbearable until 10 minutes after take-off. First class seats should be equipped with cup holders. Currently, the middle console is used and is flat and prone to spilling drinks.

Delta was fine though my flight was delayed 4 hours into LGA and my return into ORD involved a taxi of 1+ hour to the gate

Flight did not have wifi service. It was experiencing technical difficulties. Definitely and old plane that needs updating.

Very Poor. Significant delays getting to Chicago and then very poor communication on delays in Chicago to Cleveland. We could have rented a car and driven there faster than the delays ended up being.

A little more friendliness from that crew of the day.

The app logs you out right when you are boarding requiring all passwords and reservation number for the flight. Super annoying

The pre-order only approach for fresh food is really challenging

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!

We were delayed in CLT for 4 hours for mechanical issues resulting in us not leaving till 1:30AM and landing at 2:30 AM, so getting home at 4AM. The crew at the desk had no answers and provided very little information. I received a food voucher via email/app however there were no food places open. Even the walk up and scan your own places did not accept the QR code. I know mechanical issues occur but better communication would have made an unfortunate situation less frustrating.

The first leg of my trip from Dallas to CLT was smooth from check-in to landing. The snack, biscott cookie really needs an upgrade. Even if the upgrade is a choice of the cookie or pretzels.

If the service crew didn't make difference between people and they change my seat without asking me if is okay or not with me

For super long flights Premium Economy is the way to go. But the lack of WIFI onboard (don't you think it should be free on a 14 hour flight?) and the sparse personal entertainment selection made this the biggest detractors. Also, can we keep that map from flashing in our faces the whole trip there? Jesus Christ.

Great for a small Commuter. Quiet and relaxing. Seats were better than most.

The plane was late getting to Ontario by half an hour which makes it inconvenient when you have people waiting for you.

Luggage handling and communication is extremely poor. I landed in india 15th and recived luggage today. Based on my itag the luggage was in Germany. They kept me in dark. Etihad num er in india was non operatuonal. Had to call USA etihad. It should not be so difficullt. I came for 1 week business trip everything was screwed . This is the first and also will be last for me

There was no service on the flight even though there was no turbulence or any other issues on the flight. Nobody greeted at the entry or leaving the airplane, staff crew looked annoyed and not helpful at all.

mechanical problem delayed more than 2 hours on the run way.

I paid extra for a seat up front and at last minute was moved to the 2nd to last row - which I could have had for free. No reason and no refund. Really great customer service American

When I was boarding my departure from Raleigh to Orlando I was inappropriately scolded by a female dog named Mia because I didn’t pay in advance for my carry on bag ($75). Frontiers website is confusing regarding pre-paying for carryons so it was a simple mistake. I also had paid for “upfront plus” meaning me and my son were seated in the front row with no one in the middle seat ($450 upgrade). When we were boarding Mia said “sir, you didn’t pay for your carryon” in a not so polite tone and told me to get out of line and come back to the counter to pay for my carryon. The way they had the retractable rope left me no room to circle back without making the people behind me move so I just stood there and then she said a second time “sir!! Go pay for your carryon” in an embarrassing tone. I then moved their rope so I could get back to the counter when a second female dog then asked “are you done!?!?” because I had said “do you want me to bulldoze the people behind me?” I then said you do realize I paid over $400 for upfront plus so I was certainly not trying to sneak a carryon bag without paying. Long story short, I am soooo done with discount airlines!!! By the time you pay for all the “extras” you might as well have paid for Delta Southwest or American! Frontier airlines sucks and I was embarrassed by a female dog named Mia!!!

Frontier is good until they cancel your flight. Way too many cancellations.

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.
