The staff and the boarding procedure were all amazing . The one flight was not equipped with WIFI which now adays seems odd. All in all the experience was good

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.
Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.
Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.
Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.
Delta made it easy, comfortable and timely. The crew was fantastic.
This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one
Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate
Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.
Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.
The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.
Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.
Flight was delayed and missed my connection Lufthansa didn’t respond.
the delay for 3 hours was understandable due to weather conditions but the flight should’ve provided some on flight compensations or at least provide more food.
United could have one single once of customer service. No human United employee would help me with the invalid mileage plus number, they said I had to speak with the computer.
Overall it was good. I missed my connection but I was put on another flight.
Although the flight was delayed the crew and the flight itself were very good. Couldn't fault anything and after the disappointment of being abandoned in the US by BA it was a welcome relief to travel with United
Boarding experience was smooth. Flight attendants were friendly and helpful. Entertainment system on the Houston-Edmonton flight did not function for passengers on the left side of the aisle. On the bird's eye flight from Quito to Houston, they should not serve a meal. No one needs to eat after midnight and it is disturbing for those passengers trying to sleep.
Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.
My suitcase was completed destroyed. The top part is broken and unusable now.
American airlines suck they delay the flights all the time made me sleep in an airport because my flight was delayed and I miss my connecting flight
There's nothing I liked about it. For first off I scheduled this trip two weeks in advance then they delayed my flight which messed up my whole trip. So I scheduled it for the following weekend thinking there won't be a delay and guess what as soon as I got to the airport we said in the airplane on the tarmac for an hour and a half. Not only was it delayed I missed my connecting flight meaning I had to stay the night at Dallas-Fort Worth airport sleeping on the floor. I will tell you this I will never fly American airlines ever again I have had nothing but horrible experience with them and I just throw money at them
The stewardess hit me with the food kart twice on the head and didn't say I'm sorry once. The same stewardess gave me a warm Apple Juice with No ice. The Flight was delayed for Departure 6 times, starting from 2:36pm, finally taking off 7:50pm. I was late picking up my child from the sitter by 3 hours.
We will be writing a long, detailed letter to corporate about our awful experience with American airlines.
Our bags took a long time to get unloaded once we landed.
My flight was delayed for several hours. Sitting at gate 16 for several hours, I got a text from Kayak the gate changed to 9 before it was announced. Very bad communication at each gate from American Airlines employees. I received 10 notifications of delay from Kayak. My vacation started off horrible! I will write to American Airlines corporate office also.
My Internet did not work for Outlook email or basically anything. I paid for one hour of in-flight usage and it was terrible. I spent a lot of time on different sites and browsers with no luck and a lot of frustration. Other than that, the flight was on time, crew was nice, service was fine. Seat was OK even though I paid for the extra 6 inches. I cannot imagine how tight the seats in the back must be.
Delayed flight that lead to a missed connection and a 5-hour trip became a 12-hour flight 🙄
No issues. They did change our gate FOUR times in about 30 minutes which was mildly annoying but the flight was fine.
Great flight. No issues at all. I still think boarding could be more efficient but otherwise, a good experience.
Spirit Airlines was ok but TRAVELHELPDESK, the 3rd party travel agent IS A JOKE! VERY RUDE CUSTOMER AGENTS ont he phone. NO HELP AT ALL. But the airlines was ok.
The staff was very very rude in Las Vegas when boarding the flight. When presenting the boarding ticket. Las Vegas flight, it was hot and stuffy, it smelled really bad.
Unbelievable check in horrible. Asked to print tickets at the gate after a delay
check in at security was a hassle being scanned. Spirit employees were helpful and professional.
I liked how cheap it was but both my flights were delayed heavily
It was okay delay was long but I made it
I have never flown Spirit it was much better than anticipated!
Staff was very friendly. They attended to people nicely and reprimanded, in a professional way, to those who wouldn’t listen. AC wasn’t working on the flight waiting to depart in Burbank, so it was uncomfortable for a while since the flight was delayed but then better before take off.
Good on that leg. When I arrived in Detroit I had to wait over an hour for luggage.
The crew was very nice. I would like to see them offer basic refreshments just like a soda and pretzels, etc. for free.
Seats were new and comfortable. Staff was fine. Missed my connection due to weather -which wasn’t their fault- but got no help at all. Gate staff sent me to customer service, which was and stayed unstaffed. Sign with QR code directed me to call or chat. Chat was useless. Call was returned after an hour. No itinerary offered by Frontier could get me home in less than 30 hours. Rebooked with another airline and got a partial refund that came to about 10 percent of what I paid to get home.
Finally a Frontier on time and efficient. I've had problems before with your airline, but this time everything went fine.
The experience was good. No frills but I got there safe and sound and on time.
Great for the price. No wifi or entertainment, but gate agents and crew were fantastic and we boarded quickly and left on time.
sluggish boarding and arrival procedures, fake nice flight attendants, and lots of delays.
Disaster. They lied every step of the way. We ended up being delayed due to crew and then allegedly abandoned the flight because of a curfew at LGA. No rebooking to LGA at any reasonable time. No hotel. No meal vouchers. Had to sleep in the airport and fly to Newark instead. Will never fly Frontier again.
Boarding in Orlando was not good. Giant mob at the gate, should have been lines.
The ticketing agents were rude but then we had a great gate agent very nice we had to ride a buss out to where the plane was parked but it was in some back corner of the airport when we got to the plane the captain who was great btw was cleaning the plane because the same rude ticketing agent told them they we not contracted to vacuum the plane. The ride to las Vegas was fine We had a connecting flight to Dallas. The flight was fine but when we arrived in Dallas everyone who flew on any frontier airlines the picked up bags from baggage claim D15 had to wait over a hour for their bags to start we arrived at 11:30pm ish to the gate we didn't leave the baggage clamed till 12:50 am very not happy and i used to fly frontier 4 times a week for work in Denver i will not be using them again
I missed a flight because of a delay. I had to buy a new ticket through Southwest.
My flight was delayed by two hours which made it so that I would miss my layover flight. I stood in line for customer service for over an hour and when I reached the agent she told me to scan a QR code and it'll give me options. I wasn't offered any help, guidance or compensation, only told that I have options but that I had to figure it all out myself. I was refunded part of the trip and had to buy an expensive same day ticket from another airline in order to get home. I will never fly Frontier again.
