Airline reviews

I am so shocked at the service in first class. We were not greeted or offered a beverage for 45 minutes into the flight. She did however have time to write a long note. I just wanted a snack and something to drink. We were never offered coffee and the snacks came after dinner? It was the oddest flight I have ever been on. The gentleman next to me got up and gave our dinner box’s to the flight attendant and asked for a second glass of wine for each of us. Our dinner boxes sat on our tray for 20 minutes. She was rather distracted. He then asked another flight attendant for wine… finally we had a second glass. I was trying to give her some grace, she also told the man next me we couldn’t have any more wine because we drank it all… after landing the seasoned traveler next me ask for her employee number. Then it was a mutiny! She was refusing and it got tense. The captain came and asked what was happening, the flight attendants totally gave a biased account of the fact. The captain told the police the man I was seated next to was intoxicated! That was completely inaccurate and it really escalated things. I policeman found me at the luggage carousel to verify the facts. The flight attendants made false accusations that he touched them! That never happened. It was a very poorly trained crew. I am so anngry and shock by the entire experience! It was terrible service! I would like a refund for what I paid to be in first class and the most uncomfortable flight ever. I always fly Delta, it has been wonderful. I was so flustered by the entire experience! Please give me an update on this matter! Thank you, Kelle Myers

It was reported to the passengers that Delta failed to schedule the crew properly. This error caused the pilot to show up about 30 minutes late. All in all Delta's inability to take care of this basic function resulted in about an hour delay.

Late departure due to large number of wheel chair patrons. Used to having a box of snacks to select from in comfort plus. The flight attendant just rattled off what was available and asked us to pick. Felt rushed and uncomfortable. Seat was great. Prefer having the screen on the seat in front of me instead of having to pull it up from the seat side. Lots of room for my carryon under the seat in front of me.

The airplanes were so old and out-dated it was terrifying to fly on them.

It’s was good. There’s so much room for improvement though. Since the plane was small, there was no entertainment but for years now, the most jarring aspect of travel is the lack of tasty snacks.

The important things including boarding and the flight being on time and safe were excellent. The disappointment comes from the comfort and amenities. Was misled by the "availability" of inflight internet- there is an extra cost. The tray table was broken, the bathroom door stuck and flight attendants were competent but not very friendly.

The Pilot was one of the best I've had, very informative about turbulence and got us to our destination early

The Gate Attendant @ Gate B36 was rude The flight was good but the entertainment system was not functioning as expected. The snacks were ok but could be better The flight crew was excellent.

Flight was delayed, missed connectingnflight to DC. Put me on flight to Baltimore, had to rent a car for $200. Plane was old, wall peeling around window. Flight was packed, every seat full on small plane. I spent 14 hrs on Friday in airports and missed my planned weekend event.

Had us delay to fix forward restroom only to have stop working so I had a line of people's rear. The entire flight.

Everything was fantastic. Modern plane. All the amenities! Although the paid snacks and meals are pure robbery. Like i understand airlines need to make money, but 11$ USD for an overnight oats with some nuts in it and barely any pieces of apple.... Highway robbery

The flight was bumpy. No Breakfast or coffee was served, not even a bottle of water. The food was okay but odd. Rice with peas instead of couscous with some unknown green thing. United Airlines did not tell me that there was VERY LIMITED HANDICAP SERVICE IN NAPLES. De-plane via 20 aluminum steps. Taken to Van. You must walk into the terminal, find luggage, and then walk out to the rental car pickup spot that is 1 block from the terminal.

Crew did their best but the plane configuration is too tight if you're bigger than an average sardine. Controls for the entertainment system didn't all work. The aircraft hadn't been cleaned in awhile.

Didn't make it dir to delays - no support from United staff

My flight was delayed for a whole day, so I lost a day of my vacation.

flight delayed, was put on another flight after standby queue, luggage was misplaced and arrived to me 3 days later

The baggage handlers broke the handle on my bag that they put under the plane that I checked on the jetway. They traded it out for a less quality bag in Tulsa. But, they said they would try to fix it. Bologna! There was no fixing that bag handle. Someone didn’t care how they treated the bag.

Flighty delayed on boarding - then group 1 had to check their carry on bags but groups 3 and beyond could carry bags on - very inconvenient for weekend business trip with no checked baggage. Then delayed on the runway - before take off. No communication from pilot on why or how long. Wifi/Entertainment didn't work for 4+ flight. Upon arrival, attendants announced wrong carousel for baggage claim - everyone was waiting at the wrong place for their checked bags. This was a mess united!

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

I’ve had a couple flights this week on United that were delayed by an hour or more

Smoothe flight. Pilot and crew did a great job. Uncomfortable seat in this jet, felt worn out

seats were way too small. Too short of a flight to offer amenities.

The main problem was delay. The plane was at the gate early and bags were loaded. However, there was no crew for the flight. They were inbound from LGA and had to land and make their way to our gate. It took more than 40 minutes. Then, once the crew arrived and boarded, one of the crew members had to deplane and then a replacement crew member had to be found. It took another 40 minutes or so to get the final crew member. In all, we took off about 2 hours later than our scheduled departure time. Once in the air, the flight was great. Smooth most of the way. The crew was professional and efficient.

Perfect flight. Efficient boarding, on time take off and early arrival. Generally smooth flight.

American is a steady for me. I always get what I expect from them. Sincere effort to get me from one place to another.

BAD. As a family could not sit together. The gate agent told us there was only one seat in the middle left, when we got on the plane the situation was very different with whole rows of seats empty

Plane was delayed an hour causing me to miss my flight to London and now I am not arriving until Sunday instead of Friday. I am stranded at airport and they give me $12 of food vouchers. It's a joke and everyone I talked to was rude

The Airline was not prepared for weather delays. We were held up due to an incoming flight being delayed and so we did not have a flight crew. This caused an extra delay for departure by 2 hours.

The plane was freezing cold. Normally I’m fine on planes but I needed to toss a sweatshirt on this time.

I missed this flight due to delays on my previous flight.

This was the best spirit airlines fight I have ever had. I take spirit up to 3 or more times a year and I am ready to be the Jared of spirit. 🤪 Best flight ever. Everyone was great. I hope my return flight is the same. When you're traveling with a 9 month old you need a different type of care and accommodation. I didn't ask the staff for anything but I didn't have any added stress.

Purchasing tickets on their website is upsetting, they take the consumer for a ride...I wanted 2 tickets for me and my friend but we only had one carry on between the two of us. It was impossible to only pay for one - I had to pay for 2 carry ons and blew $50! Shame on their sleazy business practices! The seats in the airplane are shockingly uncomfortable! In the future I will only fly Spirit if I have no other reasonably priced choice. The flight and the crew were good. But still: Go Southwest Airlines!!!

Could at least have little recline in economy seats and windows to the last row, they were super uncomfortable and lots of chit chat and disturbance from the operation of crew members and other passengers

The plane crew made the decision to leave a LARGE group of us passengers who were stuck literally at the gate next to the Las Vegas flight & trying to get off. We were lied to & told the Vegas to Dallas plane was going to wait for us. I’m having to fly the whole night to my destination now because of this

Doubt that you care, the flight from OAK to Las Vegas took longer on the runway when we arrived. The flight attendants & pilot announced that they knew a lot of us were getting on a connection to Dallas & that it was waiting for us. Lied. Ended up having to take another layover & it’s added way more time to my flights. The ticketing staff at the gates were extremely rude. I don’t think I ever want to fly Spirit again.

Everyone on the plane was wonderful. I can't say that the trip of flying was wonderful because I hadn't done that since I was 13 years old. Honestly I was terrified. What would make it better is if they didn't drive so fast but I know they have to. And if they could go up slowly and land slowly. But none of that they can control.

Was told by one of the helpers at spirit in Detroit that I had to pay for my bag that could fit on the over head bin after I asked her repeatedly well what about the over head bin can’t my bag fit in there she said no I had to check it. Then sent me the long way to the tsa when my gate was the other way. I didn’t have that problem in Chicago.

Spirit airlines flight delays caused me to miss my connecting flight. I was rebooked in a different flight that routed through Texas. The flight from LAS to Houston was miserable, the person seated next to me was visibly intoxicated, and was served more alcohol in the plane. Upon arrival in Houston nothing was open, even TSA. I had to spend 6 hours just waiting in the airport. All in all, I arrived home a full 12 hours after my originally planned travel which out my family in a bad position. Do better!!!

Horrible airline with terrible customer service! I was at the Atlanta airport going to Ft Lauderdale. They delayed the takeoff time several times. We finally boarded & taxied away from the gate where they had us sit in a hot airplane for an hour & a half before cancelling the flight due to weather. They did not even offer us water. They took us back to a totally different gate where they said agents would be available to help. Instead, they dumped us out & left us to fend for ourselves. We had to go out of security to go pick up our checked luggage & wait in a long line at the ticket desk where only one agent was working & by the time we got to the front of the line over an hour later, all the flights were full for the rest of the day & only limited seat availability for the next day. If you were one of the lucky few that was able to reschedule the same day flying to the same or a different airport, you had to go back through security & ride the train to get back to the correct date which took over an hour more. A total waste of time. I will never fly Spirit Airlines again!!

Crew was Awesome, especially flight attendant Blake from Fort Lauderdale! Passengers onboard were unfortunately unruly & disrespectful.

The plane was very clean, the flight attendants were chipper and accommodating. It was roomy

There was extremely long wait times to check in my bags and pass through TSA. I almost missed my flights on several occasions.

I didn’t have enough time to catch my connecting flight and had to use a different Airline. I will be requesting a refund.

There were a lot of issues at the gate in Atlanta — which caused delays in boarding and getting to our destination. The aircraft and crew were excellent.

It was fine. The flight was delayed for 3 hours. I had things scheduled in Detroit, and I let a lot of people down by not being there on time.

First time experience and though you'll pay for *everything* meaning bags, water/snacks, even a question with a service agent - - all in all, not a bad experience whatsoever.

Long lines, rude staff, everything that's offered you have to pay for.

Among the worst flights I’ve taken. Never again. Staff was horrible across the entire Frontier workforce. Flight attendants were legitimately yelling at and arguing with each other while on board - toxic environment (really guys? at work and in front of customers no less?). Frontier intentionally assigned my partner and I (who booked together) to opposite ends of the plane despite plenty of seats together - straight up predatory practices to take people’s money. Seats are legit the absolute worst. Not even free coffee. Absolute garbage airline with wild hidden fees and the worst staff in the business. They will for sure have a deadly accident soon. Never again, not for any where not for any price.

My departure gate was E10 but no kiosk at E10 for check in & no one to ask. A United attendant helped direct us to E38 for check in. The kiosks at E38 were all malfunctioning. A counter agent had to check us in. We then had to walk back to E10 for boarding. E10 to E38 at DfW is not an easy trek. No where in all the info they sent us indicated there were issues to over come. They can cut only so many corners. Luckily we arrived plenty early to deal with Frontier’s inefficiency.

Our flight was delayed by four hours without notice, the app for getting my boarding pass is super confusing, and I wasn’t able to check a suitcase without paying for a higher cost package
