Charlotte concourses are under construction in some areas. Leave plenty of time for connections. We had 1.25 hrs. to arrive on one concourse and walk to another concourse for departure; this was NOT too much. Allegedly, walk should have taken 15 minutes, but moving walkways were not working, and corridors were very crowded with travelers. Gate areas are too small for people waiting to board, so they spill out into the concourse corridors, impeding traffic. Allow extra time for moving more slowly, using restrooms, getting food, etc.

I would say that for international flights, be prepared for a possibly very long walk to your gate after security check. Also, there is an agricultural check for leaving the islands that you have to queue up for before you even get inside the airport. So that is another delay to prepare for. Otherwise, it’s a typical flight, just leave yourself some extra time for these added steps.

Southwest boards more efficiently than the rest in my opinion. Boarding should start at the opposite end of the plane from the door and preferably window to door but instead it's front to back and takes forever when each passenger stows a bag and blocks the rest. I have seen the back to front work well in other countries.

I stayed at Marriott Airport the night before departure. I walked over to airport to check out the process for my ticket type which was seating assignment at the gate. Agent clued me in that the earlier I checked in the next morning, the better. And sure enough, I was first in line to check in and received a great seat assignment as if I'd paid full dollar! I really appreciated the subtle tip as I do not enjoy sitting at the back of the plane. Thank you to that helpful agent.

I would not purchase any food on these flights because they are expensive. It is best to bring your own snacks if you want to save money. Download movies onto your phone or tablet, don’t pay for their expensive WiFi! Check in on the airline’s app 24 hours prior so that all you have to do is print your luggage tags. Add your boarding passes to your phone. No more paper boarding passes which is more convenient.

I prepaid my baggage fee through the Delta App during web check-in; however, I was unable to locate the receipt afterward. It would be helpful if prepaid baggage receipts were clearly linked within the trip details section and/or accessible under the traveler profile for easy retrieval. This added visibility would enhance transparency and provide greater convenience for customers managing their travel documentation. Overall, a small enhancement that could further elevate the digital experience.

If you have a rollerboard, at least 50% of the time it won't fit in the overhead (regional jet) and have to be gate checked. I travel with a half size bag if i am spending no more than 4 days away and it fits in the overhead. That saves a lot of time when you have a connection and don't have to wait for your bag.

Bring sleeping pills. Tylenol PM or Benadryl. That one with your meal. Fall asleep in 30 mins. Wear a warm jacket and you will sleep most of your flight and wake up refreshed..

Expect the terminal in Monterey to be slightly cramped because it is a small airport. It is best to check in ahead of time on the airline’s app so that when you arrive, you can go straight to the kiosk and print your luggage tags to avoid waiting in line. They will call your name once your tags have printed. So much easier and convenient!

My advise is to pack lightly to avoid paying for the cost of one bag in the amount of 35 dollars. The amount isn't the worst I've paid, for my traveling bag but so many individuals used the overhead luggage rack as well as a back pack that didn't pay for transporting a large suitcase that I intend to do the same in the future.

United delayed my luggage twice on flight to Europe (first flight was for an important event) I carry 2 days of clothes in my backpack no matter who I'm flying with United especially so. No less than 2 hour layover to decrease possibility of loss/delay of luggage. Second EU trip my luggage was left in Germany even though my layover was just over 1 hour. Select layovers of 2+ hours although Unite will sell flights with 40 minutes layover (nonsense). 1 hour layover was not enough to transfer luggage in FRA. The last scan was 30 minutes after the flight left (SMH).

If you're trying to make a connecting flight make sure you allow PLENTY of time between flights or be prepared to miss the next flight. Make sure to use the restroom at the last possible moment before landing because you could be sitting on the taxiway for 5 more minutes... 5 more minutes... 5 more minutes... until it's been nearly 2 hours. Don't trust the airline provided ETA provided by apps they don't update it until long after you're delayed. If someone is showing up to give you a ride, make sure they have hours to wait for you.

MCO security doesn't have a mobile liquid container to drain your water bottles between the ID check and the luggage scan, you have to empty your bottles before you get in line (or drink it all before you make it to the luggage scan). Many other airports offer a space to empty your drink out, or warn you of that ahead of time, for MCO the warning didn't display until after you get through the ID check which was not helpful as there's no way to exit to find a sink once you're past that point.

Travel with a carry on only because on my flight I observed a family of (7, 5 kids and both parents) load up the overhead luggage compartments with (7) carry on suitcases, in addition to (4) back packs, which was allowed by the airline and I'm certain paid zero extra dollars as I did for three large suitcases at $35 a piece. Sane your money and do the same thing that family did.

As bad as it gets. Sign in at one terminal (40 minutes), walk to another terminal to go through security (1 hour+), then take a shuttle through taxiing planes on the tarmac to your flight's terminal (up to another hour). Absurd.. Give yourself a whopping 4 hours or you could miss your flight.

We had a 5 hour delay on the tarmac in Baltimore

Long layover between flights to Long Island from BWI - need better coordination between flights

I elected to pay for the upgrades and found very little difference

The new seating arrangement is so over priced for what you get.

The problem with the seat assignments is that there were a lot of rows in the front that were empty but my row at the back was full. Just not so pleasant.

No food or entertainment, just a quick 40 minute flight. A little bumpy due to Santa Ana winds but pilot has no control over that. Good flight and landing!

Good but I prefer choose your own seat. With the new assigned seats they should board from the back I see no advantage to this new boarding. Just like every other airline

I realize they are still working out kinks with the new boarding process, but by the time I boarded in group 5, most of the bins were full. All airlines should better enforce small bags and jackets going under the seats until everyone has boarded.

WiFi was not working and didn’t have a beverage service

Snacks are always pretzels. Why can't you also offer peanuts ?

First class is comfortable. Enjoyed a movie and was able to relax compared to coach.

Loved flying First Class. Very comfortable. The seat was amazing. Enjoyed a movie and was able to relax so much better than in coach.

We landed and sat on the tarmac for 45 minutes because they only have one gate at the airport and there was another plane running late so we had to wait

The WiFi was not working. That made for a long flight.

With Aeromexico it ended up good but with Delta it was bad because we did everything through Delta... Showed up at the Delta terminal... It was the wrong place! Nothing ever told us to go to the Aeromexico terminal. It said "in partnership with Aeromexico" but I was never instructed to check in with them or go to their terminal. We had to haul @$$ running through the airport and almost didn't make it thanks to this poor communication. 👎🏽

Absolutely no communication on why there's a delay and multiple flight time reschedules. I would have canceled the flight and drove back home if I known it was going to be rescheduled 3 or 4 times.

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.

I was in first class and literally the men behind me were so aggressively loud I moved myself to economy. This has become so common on Delta - people using audio without headphones, and men on 12am / late night flights drinking and yelling to talk to each other which prevents anyone around them from resting. Pretty crazy to have to move from first to economy (poorer service, less comfort...). Wild wild. Looking into other airlines.

Love delta smaller commuter plane so no entertainment and paid wifi on MKE-LGA leg was extremely unreliable and slow

Stop changing gates. Stop cancelling flights Stop moving my seat.

Both my flight where delayed Had 25min to make it to my transfer flight

Everything was on time and service on the flight was great!

Wifi Bluetooth features for watching in flight movie was horrible. Screen kept blacking out no connection of sound although it said connected. Other than that smooth trip .

The 777’s economy seat’s legroom was more tolerable than expected. I appreciate the reclining mechanism which slides the seat forward to minimize cannibalizing the space behind. The food was terrible: very salty.

The travel company that you have on your site did me so wrong. I don’t know how it happened, but they put my son‘s name on my plane ticket flying to Vietnam. Along with his birthday. They would not have let me fly from Fort Myers to Ho Chi Minh City. I don’t think that I can ever use your service again. I typed my information into the browser along with my passport number and four days before I’m leaving I have to quickly search another ticket to fly out here.

Seats are uncomfortable. This has been a trend in the industry for decades. Trying to fit more seats on each plane to increase profits at the expense of the passenger.

The flight was delayed so we were dead tired, and after that the turbulence was horrible. I was very scared.

It’s always a great time flying with united airlines.

Good flight. Efficient boarding and competent flight crew. No problems until we arrived at our destination gate. We were early so there was an aircraft at the gate that had to move before we could pull in. Then, due to the type of aircraft we flew, the cabin door could not be opened until some luggage from the cargo bay was offloaded to preserve center of gravity characteristics. So, that further delayed deplaning. Despite being 20 minutes early on landing, we ended up being 5 to 10 minutes late after all the delays.

Everything went well except the turbulence what no one have a control of but pilot and crew handled very good!

After changing the departure gate 5 times making us mo e from one side of the airport to the other and then back the flight was delayed nearly 2 hours. The male flight attendant had a bad attitude with the guest being condescending, disrespectful with people who were already on edge.

Easy boarding. Rows are smaller but that may be an older and bigger me now :)

It would have been nice if American tried to care.

American Airlines did everything they could with the high Spring Break crowd. I was frustrated to be changed from 1st class to a middle seat at the back of the plane. This has happened before, not sure booking 1st class and paying the extra actually works.

I booked 1st class, my flights were changed and I was sitting in the middle at the back of the plane. A far cry from the 1st class I purchased for my flights. I am grateful I arrived on time.

Aging planer and NO wifi on a 14 hour day flight. Unless you are retired or don't need to work or be in touch with the world... The lack of Wifif really ruined the flight. And the old plane - really showing it's age, wasn't great

There was no beverage service and the only time I saw a crew member walk through the cabin is when we were preparing to land.

Our flight was delayed 3 times and this is why I am giving such low reviews. Everything else was okay but being in the airport at 4:30pm for my initial flight at 7pm to not leave until after 9:30pm is insane,

Flights were constantly delayed. CRW took 50 minutes to get bags

Flight has been delayed every time I've ever taken it. Seats uncomfortable. Children behind me yelling the entire flight. Some of this is out of their control but overall just consistently not a great experience.

My flight was originally from SAT to MCO connecting from MCO to ORD. We got diverted to ATL and than Frontier staff there was sooo un helpful first they said they couldn’t give us any accommodation since our flight first got delayed that cancelled and now it’s 221am and I am still in ATL since they said they need to create a new flight my final destination is ORD and I have been delayed twice and cancelled. With no real help the frontier app didn’t work no email updates over all such a horrible experience

There's no seats that lean back with little leg space i wad uncomfortable the entire flight. Your charges for extra baggage is despicable and costly!!

Remind customers of the need to have passport or new ID for boarding.

Flight was canceled. Most upsetting was message from Kayak, stating that the flight was canceled and click with Kayak for details regarding rebook, refund details. THERE'S NO INFORMATION PROVIDED BY KAYAK EXCEPT THAT FLIGHT IS CANCELED. AND NOW THIS SURVEY TO FIND OUT HOW WAS THE FLIGHT !!!!!!!

The flight never took off and we spent 7 hours at the airport

Gate not determined until I got to the airport - hard to plan the trip to the airport.

Our flight was canceled. I will never use Kayak nor Frontier for travel again. The entire experience was a headache.

Frontier.. nickel and dime add-ons. Flight late, on time, late again, last minute gate change, arrival gate required a shuttle to the terminal. They sure keep you guessing.. if you like a little chaos and airport anxiety, this is the airline for you!

This is my second time flying with Frontier. My current experience was very favorable. The staff from the gate to the plane was friendly, warm and professional. The food options lacked in my opinion. This area needs some attention in my opinion.

First of all we hade waited 3 hours in the airplane waiting to leave. Second the return schedule was changed and it messed up my entire vaction. I won't buy never again another flight and recommend to nobody traveling with them.
