Pros: "Crew was very pleasant. Boarding and deplaning was smooth and easy!"
Read more about Delta
Pros: "Crew was very pleasant. Boarding and deplaning was smooth and easy!"
Pros: "Availability of WiFi, a charging port and media options puts Delta a step (or two) ahead of their competitors. The professionalism of the crew, as well as the complimentary food/beverage options are also excellent."
Cons: "Not the airlines fault, but my 6’4” frame doesn’t fit very well in a middle main cabin seat."
Pros: "We arrived eventually."
Cons: "Flight delayed three hours. Payed extra for an earlier flight. Very disappointing."
Cons: "Was not offered a drink in first class prior to take off."
Pros: "Flight crew was ok and boarding was really quick"
Cons: "Terminal 2 security at LAX is awful and inefficient Also plane had a malfunctioning switch and it took them 1.5 hrs to fix while we are on the plane. This was 1.5 hrs delay on a 58 minutes flight. :("
Pros: "Crew."
Cons: "Getting to Venice on time. Our late arrival cost me a 90 euro shutle."
Cons: "Have rhe right to carry at least one luggage per person at no cost. Besides carry on and personal item. Tickets prices and luggage costs are extremely expensive."
Pros: "Inflight movies and charging stations at every seat at the delta Gates and at every seat on the plane."
Cons: "We had originally reserved a window seat and an aisle seat but when they changed our flight they put us by the window seat and the middle which we didn't like."
Cons: "Denver airport is far too large for there to be such a small security check therefore it took forever and I missed the flight. Delta tried to charge me $1000 for another ticket to Albany and I decided to fly with another airline for half the price instead"
Cons: "The seats were in bad condition, I was surprised as Delta usually has well cared for interior and exterior airplanes."
Pros: "The crew was great and the landing into Denver was very smooth."
Pros: "The people were nice and helpful. And the aircraft did not feel cramped. I again did not use the entertainment or anything like that."
Cons: "Stuck me with a middle seat even though I fly frequently On United. In fact they gave me a special recognition on an earlier flight which was ridiculous as well because it was just a piece of paper that I had to go up to the podium to collect"
Pros: "Nothing"
Cons: "My email is not linked to my phone, so I got no warning notices of two gate changes waiting for my connecting flight home. I waited at the original gate (C39) from arrival time (2:30 pm) til boarding time (5:40 pm). When I saw no change to my destination, I checked the United App to find that the gate had been changed C33). Rushing to C33 I found another flight boarding at that location with one United Representative who could not stop to answer questions. Seeing two unoccupied Representatives at the next gate (C32), I asked if they could help me with the confusion, they said I should check with gate C33 - which I told them that she was too busy with other passengers. I searched for a Departure Board and discovered that gate C33 was still the gate, but "aircraft maintenance" had delayed the flight until after 8:20. After having to check my carry-on because of lack of space in the overheads, my departure from the airport was further delayed another 30 minutes. Upon returning home and checking my email, I found notifications of two different gate changes (C33 & C44). Announcements should have been made at both gate C39 about the changing of the gate and at C33 explaining the problem. The captain's lame excuse about air conditioning and Phoenix's hot weather was lame to say the least."
Pros: "Not one thing!"
Cons: "The flight attendants seemed bored and completely uninterested in passengers and their jobs. Worst flight ever."
Pros: "The app promoted me to check in on my phone and would not allow me to check in. So I assumed the time on the ticket would be my boarding time. I was late for my flight."
Pros: "I purchased a ticket for my 18 year old dog $ 125.00 each way to fly with me to Kalispell and back. She is so old that she can not SEE, HEAR, or BARK any longer. I understood she needed to be under the seat for take off and landing but I was told by the ticket agent and flight attendants on my first flight that she could sit on my lap during the flight. Everything was great on the way there. On the returning flight,.... the flight attendant was so RUDE to me. She saw that after we were airborne and at a steady altitude, I brought my dog "Kacey" up into my lap. She immediately raised her voice and stated the dog needed to remain on the ground. I politely explained her condition BUT she refused to listen to anything. I put my poor old dog back under the seat. After approx 20 min I could hear her patting very loud. I lifted her again and asked a different flight attendant for some water. She was very hot on the floor. Or course, the flight attendant saw my little chihuahua drinking the water and said that after she drinks a little more, she must remain under the seat. By now, my husband is getting annoyed. He tried explaining to the flight attendant the medical needs that my dog has " she's on protein shakes" which were approved their security. and how fragile she is. She can't BARK, SEE, or HEAR. Yes, we will be putting her down soon but we took her to Montana for my daughter to say her GOODBYES!! Sorry to say, but that flight attendant has turned me away from UNITED AIR LINES forever. Feel free to call me 352-804-8344. You may send this to UNITED AIRLINES too!! Thanks Karen Hope"
Pros: "I enjoyed my interaction with the other passengers."
Cons: "Several delays compounded to make trip a lot longer and far less comfortable than it needed to be."
Pros: "The food choices were good and the service was excellent, Always kind and responsive to my needs and attentive."
Cons: "Boarding could be done by letting people with window seats being seated first, then the middle seats next and finally aisle seats last! That way people would not have to get up from their seats after they have been sitting down to get back up to allow the people in the inner seat to get to their seats a pond boarding the plane after the people in the aisle seat are already sitting!"
Pros: "Got me home."
Cons: "Everything, see prior comments on Des Moines to Denver flight."
Cons: "The plane was cramped and uncomfortable. I also don’t like all the additional baggage fees tacked on to the original ticket price. I didn’t expect that when i first bought the tickets."
Pros: "The two flights were smooth."
Cons: "My flight was cancelled and me amongst other passengers did not get a voucher for a hotel. So I spent 18h at the SFO airport. My layover in Denver had originally been 2h this time it was 9h. By the time I finally got to Phoenix I have been travelling for over 29h. On top of it all I was charged $45 each, for my baggage as well as my backpack ($90) which I found rediculous!"
Pros: "The plane safely landed."
Cons: "Customer service, overall lack of competence and an inability to communicate laterally with other airlines who were using their gates. Seats are also incredibly uncomfortable."
Pros: "We got there safely."
Cons: "They made the flight more than an hour late so that 12 people could make a connection. I understand having some compassion, but more than an hour? What about the rest of us who, do to the sardine can nature of plane travel these days, had to all listen to each other call their appointment s and explain the delay? Also, they charge for nearly everything -- soda, checked luggage ($45 for one!), carry on. I won't choose Frontier again unless it's my only choice."
Pros: "I called Customer Service as I needed to request a wheelchair to and from gate. The Customer Service Agent was pleasant and accommodating. I while I do not like paying for my luggage to accompany on the flight, I might try you again."
Pros: "I was able to get from point a to point b with no issues"
Cons: "I was forced to pay for my carry-on which was the same price as the check in bag. The complimentary drink and nuts were a charge and I missed my layover flight because they did not announce it. I want my money back! I had to get a whole new ticket from a different airline."
Pros: "I lived"
Cons: "When I tried to get on at the last minute from Denver to Phoenix the girl at the desk right before I got on was acting like a jerk, other than that everything else was ok, definitely would be better if there was USB ports and if I'm gonna spend $7.99 on a shot of whiskey it would at least fill the glass up and the plane sounded like it needed repairs"
Cons: "I can't believe you have to pay $40 for carryon!!!"
Pros: "There was no customer service. Employees at the front desk at the airport where extremely rude"
Cons: "First and only time i take this airline. Never again"
Cons: "They canceled the flight and didn't notify us! We will not every choose to fly spirit again"
Pros: "Flight left on time."
Cons: "Seats were cramped and uncomfortable. Small plane. They charge for everything!!! Will not be back."
Cons: "a $57 fee for a carry on is a bit ridiculous. If I had know this, I would have flown on a different airline for a little bit more cost."
Pros: "It was not bad but it could have been a lot better"
Cons: "No one had cleaned Before we boarded. smashed crackers in the seats and all over the floor. Overpriced baggage!! Won't be flying them again!!"
Cons: "The flight attendants were nice, but Spirit makes it a pain in the neck to get your tickets. You first of all are REQUIRED to create an account with them so they can send you advertisements that you don't want cluttering up your mailbox. Second of all you have to pay an extra $10-20 if you want a seat. Furthermore, you have to pay extra for a carry-on. That's ridiculous! The flight was also delayed two hours, so I had to sit around the airport for 4 hours! When you finally board, the leg room is pathetic. I barely had room to fit my legs in with one small handbag! They also make you pay for in-flight refreshments. This is one of the worst flying experiences I have ever had. I am never flying Spirit again!"
Pros: "You got me there and back safe and sound. Thanks!"
Pros: "Price was great and considering how inexpensive it was, our seats were comfortable and the plane was spotless. Great option for inexpensive shorter flights."
Pros: "I like the base cost and then having the choice to add charges to my ticket designed for my needs."
Cons: "Would like to pick my seat and pay for it ahead of flight."
Pros: "i have flown spirit multiple times out of phoenix in all kinds of weather and not once has it ever taken off on time! once the airline attendant even yelled at the passengers upon arrival at the gate like we were all children. I decided to check the status today instead of waiting in the airport for four hours and yes--- again it was delayed one hour and then two hours. so I planed accordingly and planned to be at the airport 1.5 hours ahead of the revised flight time. then they changed the flight time again and now I've missed my flight. this airline is absolutely the worst and I have flown domestically and internationally for over 35 years. I'm done with you spirit!"
