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.

Allow time for shuttle ride to the correct concourse. Information desk was helpful in helping to navigate where to get to concourse D.

the traffic in Atlanta is insane, leave early!
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.

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.
DonnaFlew with American Airlines-Sep 2026
The airport is significantly under construction. No working spaces. Very few charging locations.
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

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.

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.

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.

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.

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.

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.

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.

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.

had to check bag at gate when there was still overhead bin space. As usual the WIFI didn't really work.

Terrible delay today. also, waited 90 minutes for baggage to unload in Seattle earlier in the week.

Like new plane. Great crew. Comfortable. Clean. On time. Happy employees. Good organization and control of passengers.

Flights delays were communicated timely and helpfully, but there was a significant delay without any real effort to make up for that. Also, the in-flight WiFi was very spotty. That said, this was my first time with Southwest and I was quite happy with the service and staff otherwise.

Delayed and once landed waited very long for the luggage

Nice managed … it was a smaller plane, so the seating wasn’t as comfortable.

The Southwest airline was ok. A big thank you to Kayak team (David), who worked with me on Sunday afternoon to rebook my travel from Burbank, CA, to CVG. My original flight on Sunday was delayed, so I had to cancel Sunday flight and rebook my travel to Monday. Could not have done it without help from David from Kayak team. Ante Soda GE Aerospace

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…

I was impressed with how quickly the baggage transfers were made.

The Airline Attendant found us in flight and moved us to seats in the front of economy due to the short time we would have to make our connecting flight. We really appreciated it.

For some reason, there was very little volume on the cabin announcements. You could not hear what the pilot or crew were saying.

Carmen was an absolute delight on the flight staff! Everyone was lovely and made it a very pleasant flight.

Flight was delayed at airport with large backlog and WiFi was spotty

I don’t like mushrooms and that’s all they had with pasta

I Love Delta but one of the flight crew training in courtesy snd hospitality.

I don't know why the crew decided to board 15 minutes early without informing anyone not at the gate. Why would you have the app send a notification that we're boarding on time, instead board early, and then rush me to the gate. Then have me check my carry-on when I specifically packed my bag as to not do so.

Could have been on time and not missed my connection

Really hard to tell what was happening after my flight got delayed five times

Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.

They did not have free WIFI and I was not okay with that!

Food was very bad Crew was not so welcoming. Chairs was so uncomfortable

Flight was on time, clean, etc. Despite connecting to your wi fi I was unable to use your app to watch entertainment.

I initially boarded in a very comfortable and large plane and was told there was a mechanical issue with a waste receptacle. We sat on the plan for a good few hours, then were told we can deplane and that we would take off shortly. Delays continued and four hours later my flight was cancelled, and I had to quickly rebook another. The flight I rebooked was also delayed, and I when we boarded, I wound up on a small plane in a middle seat for the 6-hour journey and it was extremely uncomfortable. No issues with the staff in any way, just the overall experience of the delays, cancellations, and downgrade in comfort on such a long flight. It is significantly impactful on how you feel post travel and I was exhausted and sore from the experience.

Awful!!!. I do not recommend United. The flight staff are unhappy and don't attempt to make the passengers feel comfortable or welcome. The food is not edible, and the seats are miserable. My expensive luggage was destroyed, and the ticket prices are too much for the experience.

Even though the incoming flight was delayed by 20 minutes they managed to get us to SFO 15 minutes early.

The business class had to wait to board last. Unacceptable

The air hostess was excellent. I have taken so many flight domestic and international, this is the first time the air hostess was so caring. She was a delight

On time, easy boarding. Anytime you sit in an economy seat, it’s uncomfortable. New plane and the bathrooms were in the galley at the back of the plane which seemed odd.

Had to pay for WiFi, delayed start, and sat on the runway forever.

As with most flights these days it was delayed by about 30 min.

The airline company should manage their crew for the plane on better schedule so people don’t have to wait in the plane. And this flight that I had had no snacks offered, and if you would like a water, you had to come see somebody and ask for. If airline would let people know that they are no longer providing or offering any food. At least people could bring their own if they wish.

The flight was delay roughly 90 minutes. Once we arrived at O'Hare, we sat on the tarmac for another 90 minutes. I understand that O'Hare is under construction however they need to figure out a solution as every incoming flight I have been on has been delayed coming to a gate.

The WiFi was out gr entire flight. Had to Diane for almost 1 hour to wait for a gate to open up for plane to dock. Very bad experience.

It was a short flight so there were no entertainments nor super comfortable which is OKAY, just the review system doesnt allow for N/A which is why okay was put, but overall good! No delays and nice crew

We were stuck with no gate upon landing for 90 minutes. Unacceptable.

It was significantly delayed. Also the admirals club in Philadelphia airport near Gate B is absolutely filthy. Good was on the floor. Flies on the cheese. And the men’s restroom had pools of urine on the floor. I am not using that lounge again.

It was good overall. On my transition from Philadelphia to Boston,the gate information wasn't correct. When I went to check the gate information; I found out that my flight was boarding clear across the airport at another gate. Fortunately I rushed over there and made it on time while they were in the middle of boarding.

For the first time in all my travels I found the arm rests very inadequate and painful. The arm rest between me and the passenger to my left was thin and didn’t support either of us. On the right side, (window side) the armrest was thin and short causing me pain mid-arm.

Flight delayed 9 hours. On tarmac for over an hour after arrival. Will never book with Frontier under any circumstances ever again.

My ATL–CVG Frontier flight was disappointing due to both an operational issue and unprofessional customer service. After everyone had boarded and the aircraft had pushed back from the gate, we were delayed because the passenger count did not match the flight manifest. The crew counted passengers approximately six times before the aircraft returned to the gate and gate agents boarded to help resolve the discrepancy. We were ultimately advised that a family had been allowed to board but not all of their boarding passes had been properly scanned. This resulted in a departure delay of nearly an hour. I did appreciate that the pilot kept passengers informed and tried to reassure us that some of the delay could be recovered during the flight. My greater concern was the customer-service experience. I am a Frontier Elite Platinum member and was seated within the first five rows. When I boarded, the overhead bins near my seat were already closed. I opened two bins to see whether my small backpack would fit. A female flight attendant sharply told me that a closed bin meant it was full, although the second bin clearly had available space. When I tried to ask whether I could simply place my backpack in that available space, she ignored me. Later, while the gate agents were working to resolve the passenger-count problem, I heard the same flight attendant make jokes about how many gate agents it takes to count passengers. She then made unnecessary comments about the male gate agent doing the count, men thinking they can do things better than women, and women knowing better and outliving men. Later in the flight, she also commented that passengers should know that the first thing they need to do is always be nice to the flight attendants. Courtesy absolutely should go both ways. Flight attendants deserve respect from passengers, but passengers also deserve respectful and professional treatment from the crew. Joking about colleagues who were actively trying to correct an operational problem, making gender-based comments in front of passengers, and being dismissive toward a passenger asking a simple baggage question were unnecessary and unprofessional. I fly enough to understand that delays and mistakes happen. What determines the quality of the experience is how those situations are handled. Unfortunately, the customer-service attitude on this flight made an already frustrating operational delay considerably worse.

Did not get on the flight, they had a gate change and my app never updated me! Trying to get flight credit

Flight was delayed by about an hour, once we arrived at LAX we had to take a shuttle to the baggage claim - it was completely disorganized. The agents at the shuttles were rude and unable to provide any information. Frontier charges extra for everything from bags to drinks - at the end it ends up being more expensive than flying the better airlines

Sat in the airport waiting for my flight for 5 hours. Finally got on the plane only to be thrown off and told that my flight was cancelled. Zero customer service. Nobody spoke to us. Just the worst

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
