Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.
Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.
Plane boarded early a quickly, was mostly full. We left close to on time. And landed early.
Flight was timely, relatively comfortable, with decent entertainment and food served. Only problem encountered was with the free messaging which I highly appreciate, but it did not work from iphone to non-iphones.
This flight was perfect. No complaints and only the highest regard for the crew and ground staff and how they executed perfectly. I fly a lot with United and would request predictability and transparency in their operations instead of last minute changes.
Survey sent before we actually left. Delay after delay. Now a crew problem.
I love flying with United. Unfortunately, I flew on an older plane with minimal upgraded technology (no Bluetooth functionality or handy charging ports). Otherwise, the flight was great and even arrived early.
They changed my seats after I checked in and I was stressed from the time I saw that information until just before boarding, when the gate attendant fixed it, but it shouldn't have happened. And if it couldn't be prevented, then the people on the phone I spoke with should have done something to help, which they did not, nor did they offer me compensation, just meaningless apologies.
Smooth flight, especially take off and landing, and great crew on board. Really loved the stroopwaffles!
Deplaning was delayed because of Jetbridge equipment issues in MKE, causing an issue on an otherwise great flight.
Not really their fault, but a 4.5 hour delay is pretty brutal
Delays to take off and to leave the plane after landing added a lot of time to this flight.
It was a red eye flight, so no meals were provided, but it was fine with snacks. The seats felt cramped and almost too narrow.
While waiting to claim my checked luggage, I discovered the airline had lost it. After a long wait and inquiries, I discovered it was on another flight. Fortunately, the airline finally sent my luggage home.
This flight never occurred because AA couldn’t get their act together.
During service there was a garbage/beverage spill near our seats that never was cleaned up. On a relatively short flight when we’re fortunate enough to actually have in flight movies available, the flight attendants pitching the AADVANTAGE credit card shouldn’t talk for the last 10 minutes of the flight so that we miss the end of the movie.
The boarding was pretty easy. However, the first class seats are not lay flat as other airlines (like JetBlue) has and therefore sleeping was a challenge.
Would have thought that they would gas up plane before everyone got on board
The flights were terribly delayed and then cancelled which forced us booking another night at the hotel. Very poor management from American Airlines
Crew was late. Baggage was late. 2hs inside the plane waiting fro de-icing and traffic. A 3:30hs flight ended up being almost 6hs inside the airplane.
Checking in at the counter was very disappointing. The lady had a very bad attitude and smart at me. She had no smile, did not greet me by name, or acknowledge me as a valued customer. Poor reflection of the airline.
Everything was great. I liked the text updates so that I never miss a gate change & I have all the latest info.
No internet on a flight over three hours in this age is criminal. Staff inattentive and dismissive
Worst flight experience ever flights canceled. JetBlue told us just did not even bother standing in line to come back in one and a half hours then without any information we had to go pick up all of our luggage and spend over $2000 in accommodation just to get home. JetBlue said that the next flight available for us to get home would be three days later. Absolutely absurd hasn’t offered to give us any compensation do not fly JetBlue horrible company. They said it was based on the weather and the weather is great in all locations that we would’ve been flying to total hoax. I think it’s a conspiracy theory.
flight was delayed for hours with no explanation. The plane was a very old aircraft.
The flight departed more than 1 hour late. Leg room is bigger than most airlines
Excellent. Although they used to greet me as a mosaic member and provide a free drink, early boarding helps me to keep coming back to JetBlue.
No music app working: no economy meal on five hour flight; hour on tarmac at the end waiting for a gate. Flight itself was smooth and easy.
Communication with the customer and stay is important. Staff off with a minor inconvenience but it worked out of course. Also this was a very old Mint Class plane. They snuck this one in on us. The updated aircraft are much better.
The flight itself was fine, but the boarding process was extremely frustrating. There is no one scanning boarding passes - passengers just scan themselves and enter the jetway. By the time my husband and I got on the plane and were halfway to our seats they determined there were too many bags on the plane and everything at that point needed to be checked. This created a lot of unnecessary chaos. They should have alerted people before getting on the plane that they would need to start checking bags instead of waiting until people were already on the plane.
In flight on demand didn't work at our seats. Only a single beverage/snack run.
Boarding and unboarding processes were pretty smooth. I gave a low score for Boarding because of how my flight was missing from all the boards at the airport, and when I checked the flight status on the Spirit website, it said it would be departing from Terminal E, gate D15. There are no "D" gates in terminal E.
The plane was freezing and everyone had on their winter coats. I pulled out my sweaters out of my carryon to cover myself and put on an extra pair of socks. They offered NO FREE drinks or snacks on a 6 hour flight. The seats don’t have plugs or charges or any form of entertainment- so I just played my one downloaded game on my phone because I couldn’t sleep because I was too cold. Miserable flight though we landed safely.
The flight was on time and the crew was very professional and accommodating. When other airlines are canceling flights Spirit is still flying with on time flights. I have no complaints and will continue to choose Spirit when it is the best option for me.
It was cheap. Spirit is what it is. I got to my destination and home safely. There was no food or entertainment without paying extra, which is fine. That’s why the flight was inexpensive.
The whole thing everything was poorly managed poorly handled spirit doent deserve to be in business period.
Nothing. It was delayed three times and then canceled and we had to drive 15 hours to get home and rent a car.
My flight was cancelled last minute and I had to pay $1600 for flights, when my original flights were $300. It was a terrible experience.
Everything was fine. I'm average height and I pack light. I'm ready for my Spirit flight.
you guys canceled my flight last minute and lost my luggage.
It’s what we expected from Spirit..reasonable cost, good for a 2-3 hour flight. Disappointed that we had a 2 hour delay in departure from DFW for a maintenance issue, but the pilot handled it well once we were outbound on a different Airbus.
Better than expected. Staff were friendly and nice on both flights.
Terrible. Flight cancelled with no reasoning and no flights to rebook. Employees were useless and did nothing to help. Did not even know where to retrieve luggage from the cancelled flight. Flyers beware.
No fault of Frontier staff: plane was very late, reached Orlando at 1 am, took a while to get luggage. Weather, gov financial shutdown impact on TSA, air controllers seemed to have multiple flights backed up. Frontier staff seemed to cope as gracefully as possible. It did reassure me that I and my new hip could adapt to travel challenges. Food/entertainment were irrelevant to my trip.
It was well done. It was my first time flying with them and I was nervous b/c I have heard of many cancelled and/or delray flights. Everything went smoothly.
Frontier is the Walmart of airlines. Frontier has removed adjustability and comfort from their seats to make the flight lighter and save gas. This makes it impossible to sleep on their flights. Their customer service is abysmal. Once, I bought a drink on the plane, and they swiped my credit card on the plane to pay for it. Then I got three weeks of daily notices from my bank telling me they tried to charge the wrong card number over and over again. I tried to call them, but they removed the ability to actually talk to someone that can resolve such a problem from their company to cut corners. The only way to talk to someone in person is to go to the check-in counter at the airport (40 minutes drive from my house). Eventually their system gave up on trying to charge the card, after 21 days of repeated tries. They don't pad their prices even a little to handle customer service issues like missed flights. They also have a blanket policy preventing helping you reschedule a missed flight if their system says you "cancelled" your own flight online. This is a major problem because their website is broken on mobile devices, the only web browser you have at the airport when their gate staff tell you that you have to reschedule your own missed flight online because they can't help you. I tried to reschedule my flight on my android device and instead, their website crashed and "cancelled" my missed flight. When I got to the counter, the agent argued with me for 5 minutes insisting that I intentionally cancelled my own flight (implying I had to buy another flight). She missed the point: the problem was that I could not buy another flight because their website is broken. I left to avoid more conflict with the "customer service" agent. I tried to redress my issue with their only other "customer service" chanel available: the contact form on their website. The response I got was more of the same: you cancelled your own flight, according to our website / computer records, therefore we won't help you. I was trying to explain the problem with their broken website that cost me hundreds of dollars by crashing / malfunctioning and resulting in a cancelled flight, but they only had deaf ears for this problem. Worst customer service I have ever experienced. I will never buy another Frontier flight again, because it is a risky, painful move that I will likely regret often.
The worst. They don’t follow procedure for boarding per group. Flight got delayed for no understandably reasons, they changed our destination from PR to Miami, left us inside a plane for more than 8 hours, then cancelled flight in Miami leaving us stranded. Poorly managed re-accommodation for a new flight and overnight stay so I have to spend in a new ticket and my own hotel room to been able to get to my office next day. Lost 2 days of work and as a doctor, patients loosing their appointments. to other flights and besides
I was 2 hr arrive in the airport and 45 min in the line . After take to my turn . The agent tell me I’m later . I can not board . So my vacation was going to the floor . Just for their bad customer service agent in the airline
2 hour delay due to late plane, wrong size plane causing overbooking, and people getting off and on the plane after boarding was completed.
Since you have to pay for overhead bags then they shouldn't be running out of space and asking individuals who paid to remove stuff from the overhead
Book with frontier airlines with the mentality that they'll cancel your flight, kick you off and lose your luggage. Anything besides that is a win. Compare prices with other airlines (to include luggage) and if frontier is still worth it, book it but know all of their policies.
