Airline reviews
Delta airlines charge $ 30,oo US DOLLARS for the check in for a suitcase in the baggage hold
Delta airlines charge $ 30,oo US DOLLARS for the check in for a suitcase in the baggage hold
Cons: "Given we left at 7:15 am, I would’ve liked some food options instead of biscuits and peanuts"
Pros: "I had heard about limited food options during covid flights but everything was tasty and generous. I always appreciate it when my initial flight books my check-in to my final stop and gives me all my boarding passes at once and Delta did just that. They were also really good at communicating updates like changes to the gate."
Cons: "People should just be prepared to be asked more questions than usual. It can definitely make you feel nervous but just remember that the new covid restrictions are stressful for flight staff just as much as they are stressful for you. Be cooperative and honest and you shouldn't have any problems."
Pros: "Kosher snacks! Thank you. Screens and outlets at every seat. Safe, controlled Covid protocols including de-boarding. Excellent!"
Pros: "Delta flight took extra precaution to keep all passengers safe before during and after the flight. They communicate effectively during the flight. I will be flying Delta again and again."
Cons: "The trip was great"
Pros: "Super friendly and helpful with connections."
Cons: "The music on the plane was a bit much. Lol"
Pros: "Flight was on time and crew helped find a place for my violin. Even though I was early to the gate, they also helped me update my seat before the new flight crew arrived."
Cons: "I would ask that the gate does not share in detail reason for delay in seat assignment is related to getting a family sitting together when the basic rules should apply unilaterally."
Pros: "Got to my destination without any issues"
Cons: "Seats/seating area are too small, and I'm not a big person."
Pros: "No"
Cons: "The flight was delayed almost 6 hours, the crew was rude and the “comfort +” seats had very little leg room ."
Pros: "The crew was fantastic and plane was clean"
Cons: "My entertainment video player had a bad earphone jack so i could not watch movies or tv and resorted to paying for wifi"
Pros: "Really easy boarding and flight. Great in flight entertainment options."
Pros: "Flight attendants were friendly and thoughtful."
Cons: "Seating is too tight. Hard to believe that in 2019, major airlines still have seats without any electrical or UBS outlets for charging devices."
Pros: "Crew was great."
Cons: "Plane was about 1000 years old and I don’t think I’ve sat in a more uncomfortable seat."
Cons: "I was apparently "flagged" by British Airways for extra security checks. As I understood it in London, I was randomly selected for this security check. This then apparently meant that I was to be flagged for all subsequent flights. This meant that in Chicago, after going through two other security checks that day (Zurich and London) and completing customs, I had to engage in a full Homeland security check. This involved removing protective covers from my laptop and phone that were hard to get off (not meant to be taken off regularly) and a full body search that I did not have to do in London. After many hours of traveling, this was very a frustrating experience."
Pros: "Flight crew was great. The plane was half full, so the attendants allowed us to move."
Cons: "Terrible landing in Charlotte. The plane was rattling and had an annoying whistle."
Cons: "British Airways/American Airlines lost/delayed luggage again! Then send an email in the middle of night with a link to schedule home delivery of the luggage that was valid for 4 hours only. It is clearly an attempt to cheat out of their responsibility of home delivery of the luggage that was delayed the second time. Poor, poor service by American Airlines."
Cons: "Flight was delayed for more than 4 hours with little communication from staff as to why, gate was changed to a gate across the airport."
Cons: "Three + hour delay out of ORD, equipment problems. Even though she had a boarding pass, they would not allow wife to board. Some ticketing problem between AA and BA. Finally, they let her on. We were the last to board."
Pros: "Our plane was late getting to the gate. They kept us informed and turned it around pretty quickly. There were storms between Chicago and Rochester so we were rerouted. As a result the hour flight was an hour and a half. The pilot kept us informed and it was a very smooth flight. So even though I was over an hour late arriving I so appreciated the communications and the safer route. AA seems to be communicating more than other airlines and I appreciate that. Flying is absolutely no fun anymore so you take what you can get for the positives."
Cons: "WiFi wasn’t working so I couldn’t communicate my late arrival to family picking me up."
Cons: "Crew were not friendly at all; I was sitting in the very last row and could hear them complaining about various things. The passenger next to me asked multiple questions and was flat out ignored each time. The seats were very cramped, the flight delayed; a friendlier crew could have made up for that"
Pros: "Flight attendants were absolutely amazing!!!!! They made the trip very enjoyable!"
Cons: "Food!"
Pros: "Nothing at all!!! That should really tell you something!"
Cons: "The staff were rude, abrasive, ignored several passengers that were trying to get her attention before take off as 2 overhead bins were wide open and full to the brim. She of course was too busy playing on her cell phone in the back of the plane and ignored/silenced the passenger call button. They were so loud when people were sleeping, yelling ‘trash please’ every 5 minutes, we are not stupid, we can see what you are doing and if we have trash, we will give it to you - so please STOP disturbing my peace and let me bloody sleep!!!! I was never offered any food or drink during the entire flight, not even when I was awake - other airline attendants are more observant and come back and ask us when we are awake if we would like anything to eat or drink. So essentially that was 7 hours with nothing after having paid a little over $700 for what was seemingly the WORST transatlantic flight I’ve ever taken. I travel back and forth often, because I’m a dual national, but I will stick to BA or Virgin Atlantic - the planes and service are far superior to this pile of turd that goes by the name of United. There were no charging facilities (power outlet or USB port) and the TVs had such horrendous resolution that you would get a headache from having to squint at the screen."
Pros: "Not very many people on plane so we were able to space out more."
Pros: "The plane was newer at least. And I made a big enough stink when they made me check my bubble-wrapped framed paintings that they actually did get hand carried and made it okay."
Cons: "These are the smallest seats I have ever experienced on a domestic airline. I'm 6'-4" and I couldn't fit comfortably on their newer 737. The thing that took the cake was that the cabin crew absolutely refused to let me take one of the 5 empty exit row seats telling me that it wasn't fair to the people who paid more, which absolutely enraged me. So then apparently it's also fair that their seats will fit someone who is 5'-4" comfortably but not someone who is 6'-4"?? So it's fair that I can't afford to pay an extra $100+ for it after my profession got gutted in the recession and I make a fraction now of that I used to make? Making your customers suffer for no good reason is inexcusable. I will not be flying United again. Ever."
Pros: "Not much."
Cons: "Originally, there was an announcement that we would be delayed by 45 minutes because of "air traffic" issues in San Francisco, where we were landing. In spite of this, the captain decided to have passengers board the plane, and try to push our way up the line, so to speak. Well, once we were on the tarmac, the flight crew were told that the plane could not take off, and that we needed to wait there for 45 minutes, without moving, in our seats, with nothing to do. Even though it would still not have been ideal to wait 45 minutes at the gate, at least we could have walked around and could have entertained ourselves."
Pros: "Crew was attentive."
Cons: "From Gregory at the check in being rude and anything but welcoming, to seats in first class needing replaced, this was anything BUT a first class trip. This was my second time giving United a chance as I normally fly Delta. I don't think I'll make that mistake again. I understand a late night flight doesn't have a meal service, but snacks of chips and bananas is not my idea of how you should serve Firat Class passengers. I would have a hard time recommending anyone choose United as their airline. Time for an upgrade of not just the seats, but overall customer service."
Cons: "Worst customer service of my life. I will NEVER fly United Airlines again."
Cons: "2.5 hour delay. No working bathrooms. Couldn't hear the tv and headphones that they gave out were useless."
Cons: "Terrible experience in onboarding.. Later on i was made to sit in flight for 5 hours at mumbai airport"
Cons: "The flight was super delayed because Frontier was sharing a gate with another airline..."
Pros: "Crew was super nice"
Cons: "Delayed 3 hours, boarded and was told would be another 30minutes because of mechanical issues."
Pros: "We got delayed because the plane broke down. Everyone else got $100 credit, but I didn't because I booked through Kayak. Could you please give me the credit?"
Pros: "Fast boarding and that's the only good quality. No refreshments or snacks offered without a price tag included. Seats don't recline. Uncomfortable hard seats without any head rests for Support. Small tray tables that won't hold a laptop or drink."
Cons: "It's been 45+ minutes after landing that we have been stuck on the runway unable to dock the plane due to some delays. How Terrible is it that the pilot gets on the radio to say he has no updates or much information to give! People are antsy, children crying and this delays all passengers with other accommodations. Seems like there's no communication or organization from Frontier at all!!'"
Pros: "Easy"
Cons: "Shared my row with 500lb people and though two rows ahead of me had two empty seats I couldn't move to be comfortable. This beast of a woman couldn't put her arm rest down and therefore her body was smashing mine the whole time. It was disgusting."
Pros: "The crew had a great attitude and was able to make us laugh despite the fact that we were leaving late."
Cons: "The plane was dirty- there was balled up gum wrappers, food wrappers, and bites of food on the airplane floor. To make maters worse the carpet was already stained in multiple spots. My tray table also was dirty with sticky soda that had spilled on a prior flight. I was quite disgusted by the condition of the plane."
Pros: "Crew was nice"
Cons: "Charging passengers extra for carryon bags and certain seats is ridiculous. The majority of the plane was empty which means you could have just moved to a different seat (that would have cost $11 more) once everyone boarded the plane. There is really no purpose behind the additional charges and negatively impacts the experience."
Cons: "On flight from Tampa to Chicago nobody charged me for carry on,and on a way back they charged me 60 dollars,so,this is the last time to travel with Frontier"
Pros: "The cost of the flight was very cheap, which is nice when you are flying somewhere far like Chicago to California (usually one way can be over $200). The boarding process and crew were all very nice."
Cons: "You get what you pay for. The seats aren't the most comfortable and you don't have the best legroom. Also, pack light so you can fit everything under the seat and avoid extra costs. Good for some travelers, but not for everyone."
Pros: "They only had one plane, it was weather delayed at its previous airport, then it ariver with mechanical problems. Customer service promised me the flight would be leaving that day, it ended up being cancelled. We were at the airport for 9 hours before they cancelled which meant that rebook in a flight on a different airline cost twice as much and was difficult and could only be done for the next day. Customer service was useless. The gate crews are third party contractors and can't do anything because of frontier's policies. I reported them to Dept of transportation and they keep sending the response that they have too many complaints to respond to and they wI'll get to it eventually."
Pros: "No service issues. Our seats were arranged so the family was together for no charge. We were given a bottle of water to mix baby formula for no charge."
Cons: "Hard seats"
Pros: "Utilization of Kiosk, check-in, boarding, crew, and pilots. The seats were clean, too. Thank you very much :) !! Flight was also on-time for departure and arrival at destination. * In the Review, put my name as Anonymous. Thank you."
Cons: "Prices for beverages, food, and/or snacks are extremely HIGH! $3 USD for a 12 oz. can of pop OR WATER (16-20 oz) ? ! ! $7 USD for a 5-6 oz bottle of wine ?! The prices are ridiculous!! You can't get water to cry with or if you were on fire. Upon viewing your menu, there is a "bundle" for three or more items. This IS NOT a bargain. You decrease the price by a dollar is nothing. It appears to be overly enrichment and a rip-off. I know that you're in business to make a profit. But dayumm!! REALLY??! You all are certainly taking advantage of your customers. There may be either a continued decrease of purchases or none at all. I noticed that there weren't many purchases in relation to the number of passengers on board at the time. BTW, the price paid for the single bottle of wine ($7 USD) is what it costs for the 4-pack, if not less. A person can purchase 750 ml or 1/5 gallon for the same amount or less (i.e., $5 USD + tax). This is wrong and obliges passenger to make a grudging purchase out of necessity. Have you ever been thirsty before? Can't have water to take medications without spending large amount of money. You can't even get tap water or courtesy cup of water / ice. What type of mess is this? $50+ bag check fee is horrendous!! Your competitors are much cheaper. Please add more cushion and room to your seats. Had this flight been more than 90 mins., I'd be making a trip to the hospital instead of home."
Pros: "Great for anyone simply looking to get from point A to point B - no fuss!"
Pros: "No way to contact wheelchair assistance when being dropped of to begin flight. Waited 30 minuted for a wheelchair. Had to ask Amer.Air agent for help. Other airlines are far more attentive. Seats need 2 more inches, felt squished. Very costly baggage policy, charge for carry- ons."
Cons: "Seats did not recline ( the whole plane - not just exit rows). All the extra charges for EVERYTHING were ridiculous, especially as you are not informed of any of them before booking. I'll not fly Spirit again."
Pros: "Friendly staff, fast flight, and no frills fares. They'll charge you for drinks, etc., But overall a good flight."
Cons: "Uncomfortable seats, no free water."
Pros: "Glad I tried spirit! Got me in early on both legs of my flight! Also glad I got the comfy seat-SO worth the money!"
Pros: "Change of gate wasn't fun but it was handled professional."
Pros: "Nothing"
Cons: "They didn't seat me and my husband next to each other. Take off and landing was rough. Everything cost extra. Bags snacks drinks. Only 1 bathroom. Crew was rude. Taxiing felt like whip lash."
Pros: "Of the 6 flights I took with Spirit on this trip, this was the only one where they boarded the flight in a timely and organized manner by using the zones printed on the boarding passes."
