On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

10.0 ExcellentAllan, May 2024SUN - SLC

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

The pilots were good. Disappointing when planes don't have electrical ports

I liked the piloting of the aircraft. Very disappointed about lack of electrical ports. Also, although a short flight. there was enough time to hand out snacks to comfort + seats as was done for first class.

I had a wonderful experience flying with delta. The gentleman taking care of us on our flight was so nice, accommodating, and attentive. He always was smiling and giving pins to the kids which made me smile. The flight was quick too and without turbulence. Thank you for the great flying experience.

Delta is one of the best airlines I have flown

Made the Atlanta to Pittsburgh trip many times, with Delta no issues

Crew were fine, drinks and snacks were as well but we were delayed for around 2 hrs which made our entry into Mexico delayed as well with the influx of arrivals at the same time. Sort of wasted our first day of vacation. We left Pittsburgh at 630am and did not arrive in Mexico until late dinner time.

Boarding was unorganized. They expected passengers to ask people to move their assigned seat they paid for in order to sit together. The seats even in comfort are smaller than other airlines and the flight attendants appeared not to be well prepared

Due to one crew member not showing up to work, our flight was significantly delayed causing us to miss our connecting flight in Houston to Mississippi causing us to be delayed by more than 6 hours and missing our event all together. Very disappointing. All because ONE crew member called in sick. United did grant us a $15 meal voucher, which was a small but appreciated concession that I wasn’t able to use because I ordered my lunch and paid for it before applying the concession, and the staff said it was too late to use it. Ugh! We also had a TWO delay coming back from Mississippi, but that was on American Airlines and it was due to weather, so not their fault. Anyway, not at all impressed with United’s handling of our flight and the HUGE disappointment of missing our important family event for our 90 year old mother. All that money and all that stress and emotions for nothing. Having to wait the hour to bring an employee from LAX seemed like something that should not have happened. Why don’t you have a local back-up? Santa Ana is not a little airport in a rural area.

Trip was smooth bumpy from the wind but no issues at all the crew attendant was very pleasant and had great customer service

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

Awful. I got stuck next to a person carrying a dog and behind someone with a dog. People need to board these dogs downstairs. The cabin is crowded enough with your pets

It was delayed several hours which delayed our connection in Denver. Not happy.

Ok, but comfort was lacking as the seats were way to small

All good except paid for wifi that did not work

Some of these FA’s need attitude check. Snarky bitches

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

this is starting to seem like an american airlines standard. delayed flights and fake apologies… getting tired of it

Flight boarded without pilots. Sat on plane for 3 hrs. after over an hour late boarding. Plane never took off. Had to deplane near midnight. Line for rebooking was 3 hours + long. I had to leave.

Missed the flight because of them and up geting a rental car

Delayd flight out of atl as always miss my conection in dfw no flight untill next day

No problems with flight. Even though I had a short layover in DFW, I was still able to easily make my connection.

Good flights. Departure and arrivals were on time. DFW was a little problematic in that the Skytrain without prior notice bypassed the Echo terminal so that delayed my arrival at my connecting flight.

Late boarding to clean plane from previous flight; initial boarding announcement not loud enough; fantastic cabin attendant front of plane

Delayed flight, few announcements with information, no comps, cluster f boarding because zones weren’t spread out and announced loud and repeatedly, staff did their job -nothing more nothing less, annoying kids were speaking and kicking the heck out of the back of my seat and parents weren’t willing to parent… so another typical day of air travel in the US.,

Gossipy flight attendants talked the whole flight about bar hopping and dating.

Seats suck, not enough room, overcrowded planes, hectic situation all together.

They charged me 212.00 for a heavy check in bag at the gate. The pricing and process was so confusing - as if it was designed to purposefully gouge customers who need to board plane. That experience combined with the outrageous price charged will prevent me from ever flying Spirit again. And I’ll be sure to tell the story to anyone who cares to hear.

On time and fast. Overall it was a pleasant experience.

3 hour delay was brutal though not Spirit Airlines fault. the control tower would not let us take off because of weather

Beware of all the extras. Nickel and dimed. Everything was extra. It turns a $90 fare in to a $400 fair quite easily.

It would have been nice to have been on the flight

Delayed several times. Flight was to arrive at midnight and it arrive at 3 am. A 3 hour delay is already bad but one that has you arriving in the wee hour is just disruptive and overall unacceptable. The complete lack of restitution is a joke in keeping with Spirit’s reputation of ranking bottom-low in the pecking order.

It wasn’t as horrible as I would have expected, however, to not provide water and change so much for bags is a ripoff to say the least.

Cancelled my flight , currently stuck in Houston and will likely miss my cruise

The flight attendants were very personable, extremely friendly, and had a very good feeling of the energy around them not to mention they’re very funny and engaging. What made up for the discomfort of the seats and the fact that the plane sat for a long time on the Turmac. Not sure if the pilot was new, but the landing was very rough sort of like I was at a magic mountain theme park ride that was built in 1959

Flight was a little late taking off. Seats are too upright, no ports to charge devices, no wifi, no entertainment

Six hour delay. Poor customer service. No voucher. Bad communication. Missed important appointments.

Our flight was delayed an hour, then when we got to board our flight finally, we were waiting in our seats for take off for 45 minutes before it was communicated that there was a maintenance issue therefore we waited on the plane for over an hour while that was resolved. We did not get to Phoenix until almost 3 hours after we were originally supposed to. This was the first and last time I will be flying Frontier.

Flight was canceled with little warning. Flight was rebooked through Ontario, California and connecting flight was delayed by over three hours. Frontier is living up to their Greyhound of the skies reputation for sure.

I purchased a carry on bag online…was supposed to cost $72 but after a whole slew of bs charges, the total was over $175.00. Because of these hidden charges, I will not even consider flying Frontier ever again. It’s just not worth the hassle. I’m scratching this company off my list forever.

Flight was OK. Seats were good no cell phone charges on the plane no TVs or entertainment.

There were 3 leg for the trip and each leg was delayed by 90 minutes or more. The boarding process takes forever with people waiting on the jetway even though most folks do not have carry-on. The whole process is poorly managed.

Flight cancelled and was told by a rude gate agent that they don’t accommodate on other airlines. Had to wait 5 hours for a connecting flight that had a 7 hour layover. Would not allow bags to be checked early so we couldn’t go through security .Had to rent a car for the afternoon to store bags and get a meal. Also incurred a hotel fee. No apology or reason given for the cancellation- just rudeness.

They cancelled the flight then did nothing to help us rebook. It was awful - I won’t fly with them again

The process of buying the ticket and navigating all the hidden charges that Frontier throws at you was a terrible experience. The actual airport experience and flying was fine.
