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.

Worth being a SkyMiles member for the free checked bag Plan extra time at Miami, the walk from the MIAMover to the check in was very far and the moving sidewalks were not functioning.

At Miami International, after check in at ticketing, be aware of the long walk to the American D Concourse. Signs are confusing, as there are several ways to go depending on your gate number. Stop and ask for clarification often.

Miami is a big airport with a lot of international flights, so give yourself enough time to get through TSA. Expect last minute gate change that is possibly 20 or more gates away from the initial gate provided.

Getting to the airport early is a must. Have a plan and map for your airline's checking desk. If you ask someone for directions, make sure they are clear or that you understand, a lot of TSA and airport personnel spoke English with hard dialects and some didn't know where the Alaska Air terminal was.

It is a good connection, it gives you enough time to go through passport control and luggage claim and drop off. Eat close to the boarding gate because the next flight lasts 6 hours and there is no food service on the plane.

On the return flight, flight attendant Britt went out of her way to inform passengers that several of us had tight connections.

Too many people are taking up space in the overhead bins with their extra piece of luggage. Since they cannot fit their backpacks or extra luggage piece under the seat in front of them, they store it in the overheads and thus taking up room for other passengers. It wasn’t only one or two persons; more like 12 or 13 passengers.

Kayak botched up the booking, i had to call delta and fix. In the process Delta failed to honor my comfort plus seat assignment that i had previously.

Perhaps when you’re sitting in 1st class and the crew closes the bathroom for the pilots, there could be a notification other than holding your hands up as a blockade when you get there and you’re told the restrooms are closed please turn around … especially at night when visibility is poor and you’re met by a flight attendants with their arms up

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

An awesome flight crew. FC seat cushion just doesn’t cut it for a 3+ hour flight.

Delta continues to set the benchmark for traveler-friendly service with minimal disruption and clear communication within the mainland US (coast to coast). I am consistently pleased to be a Delta customer, and this experience once again met my expectations. There was a brief delay departing from MIA due to a technical issue that required the aircraft to return to the gate. However, the situation was handled professionally and transparently. Fortunately, my planned layover allowed ample buffer time, so the adjustment caused no stress. Overall, another smooth and reassuring experience.

Totally worth the miles to upgrade to Delta Comfort. Plenty of legroom.

This was my first time flying Delta ever and I had a great experience!

Flights were on time actually early service was good and crew cheerful

The boarding process was straightforward. One pertinent observation regarding all boarding procedures is that if an individual requires assistance or possesses a special status and is part of preboarding, it is advisable to limit the number of passengers who can preboard with them, rather than the entire, sometimes large, companion groups. The seats are uncomfortable, and the entertainment options are significantly inferior compared to other airlines. During the snack service, I requested an additional bag of snacks, but my request was denied. Initially, the flight attendant agreed to my request.becoming a strange accurate moment. The flight duration was four hours.

Flights were on time. Free Wifi on plane. Everything was well organized.

Experience was great - no complaints. Took off on time, landed early. Got to the gate relatively quickly - took a little bit of extra time to deplane but nothing excessive.

Economy plus was so cramped I could not use my laptop. It was beyond bad.

United is one airline which regardless of how many separate United tickets in existence, if one flight breaks down, the airline will take care of all the flights.

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 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.

Plane outlets in my row not working to charge phone. Staff response was, well it should be. Plug into seed for volume not working well. Had to find the sweet spot for plug in or it would shut off and on.

Bag drop was very disorganized in Miami. All main cabin passengers were shunted to just a few lanes and they had an equal number of lanes for first class passengers but there was nobody on those lines. They did nothing to bring the main cab and passengers over to the open lines and they just had employees standing there and doing nothing

Crew at the gate was very crabby and not at all polite. The plane was very hot the entire flight. And the seat cushion was very worn out.

I have never been assaulted they way I was today in Charlotte - shame on American

The staff are very, very professional. It's what flying should feel like.

The flight attendant in business class was excellent! Professional, friendly and attentive.

A first class seat should fit a fat person, and this doesn't. The trays in the armrest are less functional than an ordinary tray in the back of the seat.

It was great. Smooth flight, comfortable, left on time and landed on time.

Really good. I accidentally left my duffel on the plane and the reps were so friendly in retrieving it.

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.

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.

The attendant at the gate was not helpful at all and she was rude when we asked why the flight was delayed.

a weekend long saga that ultimately led to a canceled trip. totally unreliable.

Long long delay, no AC while delayed, gate changes, just for the most uncomfortable flight of your life.

Everything was smooth sailing. Great crew, easy flight and was surprised with an upgraded seat. Thank you all!

My first time experience with Spirit Air was not good at all.The reason i did not know to cancel 24Hrs before flight depature you do charge cancellation fee. It's ridiculous policy.Actually you should provide full voucher instead of charging cancellation fee. Confirmation Code# ZNVPHG Thanks Much , Rita S

I truly admired that the last minute flight attendants were willing to come to serve flight # 1465 and think they should be extra compensated. Doesn't have to beonetary a star a permanent position with Spirit as long as she flies etc. They were o so pleasant and accommodating. 😊😊. Please also serve water. Plain unadulterated water 💧! Invest in a filter of your own the cost of bottles are a penny on the dollar and you could have a plug on advertising with labeling. This could be hilarious "WATER TO REFREST THE SPIRIT FROM SPIRIT ITSELF!" - Free idea!😄😄😄. Anyway overall, though a tad late the flight met expectations. Thanks you Spirit, for everything.

The ticket price are reasonable, however, they can do better with the price on the luggage. Overall, I will continue using spirit.

That this is my second time the they cancel flights and they always wait until the last minute to let people know

Spirit is always late. Every single time. Always a different reason

Spirit is awful. Do not fly spirit. Nothing but delays, cancellations.

It was an early flight and most people napped/slept and the crew let us which was nice.

It didn’t happen. I booked it and then was told it wasn’t available and then forced to pay far higher prices for a worse option

This company socks. It's fraud. They canceled our flight yesterday, and today we were late because of a really long line at the check in bag. At the rebook station, there was ton of people. The workers were all rude. I am gonna make a report to FTC.

Flight got delayed for 5 hours no good explanation was offered ;(

There was no one at the counter to assist with our check in. The app didn’t work, so I arrived at the airport with time to check in and I couldn’t because no employees were there. When I finally got someone on the phone, it was inside the 60min rule and they said I could no longer check in and they could sell me another ticket. We had to scramble and pay an additional $800 for tickets and THEN AFTER (about 60 min from my original convo with customer service and 10min after original departure time) I had boarded my new flight, there was email saying my original flight from Frontier was delayed and leaving 2hr 50min later, but I STILL wouldn’t have been able to check in. Which means customer service should have been able to see it and let me check in because I was well within my check in time. When I call Frontier, they hang up on me. So their app didn’t work and they employees left and they take zero responsibility or assistance with their “customer service”

Everyone seemed to be in zone 1 for boarding. Maybe break it up a little. Otherwise, smooth flight.

The experience was good. No frills but I got there safe and sound and on time.

After boarding and un-boarding twice over 6+hours, the flight was canceled.

Severe turbulence. Captain never came on to reassure passengers after things settled down.

Boarding in Orlando was not good. Giant mob at the gate, should have been lines.
