Flight was delayed over 3 hours. Planes were dirty. Staff indifferent. And they serve vegan pretzels as snacks.

Airline is not very senior friendly. Flights are late, forcing us to run to the connecting flight. Food is awful. Wish they would go back to pretzels and peanuts. During flight, pressurization isn’t quite right and all of our ears get plugged. Everything is nickel and dime, charging for boarding, seat selection and legroom. While a screen at the desk in the gate area says check your roll on bag now for free due to space limitation, the employee at the desk will not check the bag without a $100 fee. Insane.

The flight was smooth. The Southwest experience has degraded overall, but this one was okay.

The checking experience in Orlando was terrible, almost missed the flight. Too many travelers and Southwest completely understaffed.

Seats were very comfortable. They tilted back. Drinks and snacks were free and served 3 times. Attendants were awesome.

no service at all due to turbulence. they should've at least given us snacks, there were only 10 people on the entire flight.

Everything was great except the food. The pretzels are really crappy.

Overall is was a pretty good flight. However we were 15 mins late taking off and no one told us anything. We were all in our seats just sitting there for 15mins and all the sudden the pilot stayed we are leaving now. I think they should have at least said something after our take off time passed. Everyone was wondering what was going on. I will say the pilot did increase the speed of the plane so we arrived in time. So we weren't late.

Being paid like a full service airline , I felt some features like no screen on seat, very poor entertainment content and no headphone provided. I like the checked bag benefit. Open seating concept is not nicely implemented as people were boarding out of order.

2 hour delayed departure, then sat on the tarmac for 30 minutes waiting for a gate in SRQ

1 flight cancelled Had to fly out of different city Flight at new departure city was delayed 3 hours causing us to miss connecting flights. By the time we did make it to Prague our luggage did not. Had to wait day and a half for luggage to be delivered. Customer service was not good. Agents did not arrive at gate until 5-10 minutes before boarding

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

Boarding was great, and the crew were very friendly. The seats must have been a bit on the older side and you could feel some of the seat components through the padding. Also, the plugs did not work on the row's entertainment screen or charging ports. Checked bag was transferred for connecting flight, and we appreciated how early we had the connecting gate information.

There was no WiFi available, there were mechanical problems with the plane and we landed at C 124, then the gate was switched to A 26, then all the way back to C126! For a 75 yo woman traveling alone, this was a difficult journey, indeed!

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

Very bad! They kept delaying my flight and wouldn’t do anything about it

The flight from Cleveland to Newark was great. The connecting flight wasn’t so good.

Flight was not comfortable and crew was rude and not wanted to help, i would never choose united if there is alternate options . not cooperative with baby

Crew did not arrive for their shift and flight delayed for 2 1/2 hours whilst new pilots were found. The man at the boarding gate did a great job keeping us informed and the eventual flight was good. It was just the long delay waiting…….

Seat comfort is still an issue. Seats way too hard or lacking lumbar support. Entertainment system has lots of nice features like “Don’t wake me for meals”. The Bluetooth headphone pairing works well if you know how to make your pods available for pairing. While this trip I didn’t find any of the many many movies that interesting, there is plenty in there for all tastes. Crew were excellent. Captain was good about telling us how limg seat belt sign would be on while going around a storm system. Wi-Fi was quite good for only $8 bucks for mileage plus members. Be sure to load a credit card into your United app to pay for food or drinks.

Terrible steward... Plane was quite empty... I asked to move "back" in the plane and the steward said no... Unnecessary power trip of mediocre people.

It was a typical flight. We had a delay which seems to be the normality now. And we had no in flight service due to conditions.

It was a code share with Alaska - would have been great if I actually made it on the plane, claimed I didn’t have a ticket or a seat even thought I was checked in.

Plenty of overhead space but forced to check my carry-ons both legs

The flight from CLE to JFK was fantasti! Pilots and cre were informative and accommodating.

Everything was ok except that we had to de-ice the plane which took about 20 mins. I realize this is a safety issue, but it caused us to miss a connection in Charlotte by 15 mins which meant a four hour layover. I think the thing that bothered me was American Airlines knew we were only 15 mins late, so couldn’t they have waited for us? There were about 10 of us that had to take alternate planes. I remember recently waiting 15 to 20 mins for passengers connecting with flights we were on. Just wondering why they couldn’t do the same for ours.

Another American flight delay. Gate staff was gratuitously abusive of anyone expressing frustration. This will be my last American Airlines flight

Abysmal, getting delayed approximately 13 times, having to switch out a crew with another crew that timed out within an hour, and customer service representatives that abandoned the stranded travelers. Terrible service

Flight attendants used to be nice to people. And any flight over 5 hours should have some kind of food other than tiny pretzels and one drink comped.

My luggage was lost during this connecting flight for nearly my ENTIRE 2 week stay in europe, this issue no doubt instigated by my original flight being delayed 6hrs I did not pack my "personal item" with anything of consequence, I had to buy CLOTHES & TOILETRIES TO LAST ME 2 WEEKS

This is my second time flying with Frontier. My current experience was very favorable. The staff from the gate to the plane was friendly, warm and professional. The food options lacked in my opinion. This area needs some attention in my opinion.

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.

Finally a Frontier on time and efficient. I've had problems before with your airline, but this time everything went fine.

My costume jewelry was stolen out of my bag. Got to airport and my bag weighed 45 pounds- 5 pounds over cost me $100 Long lines in tier one. No entertainment No WiFi no free drinks or snacks

I did not like that people are purposely split ip who book at the same time because we didn’t buy seats. No other airline does that.

There was extremely long wait times to check in my bags and pass through TSA. I almost missed my flights on several occasions.

On both our outgoing flight and our return flight, Frontier split up our seats. We were two adults and two small children, one an infant. Both flights were only about half full with full rows of empty seats. Yet, the airline split us up. No, we did not spend the extra $40 per person each way to purchase seat assignments ahead of time. But should we have to do this? If so, then the advertised ticket price was $40 off. What makes this even more egregious is that the plane was not full. So, there was no reason for Frontier to split up our group other than to extract an extra $320. A stewardess even had the nerve to tell me “if you want your family to sit together, I recommend that you purchase seat assignments next time.” On a half empty flight? Ridiculous. We will not be flying Frontier again.

The Frontier app wasn’t working. So I could not pay for a carry on the week prior to flying. They charged me 99$ at the gate to carry on a duffle bag.

I fly Frontier because it’s affordable. I understand that the seats are tight and not the most comfortable…but that’s part of it. The problem with this flight was that there was a group of travelers directly behind me at the back of the plane who were ridiculously loud and obnoxious the entire flight. I’m pretty sure they were drunk and I could periodically smell an odd odor that I believe was one of them using a smokeless vape pen. The stewards had to remind them to keep quiet during the pre-flight instruction, but that was it. They never said another thing to them for the rest of the flight. It was a miserable.

Flight delayed 3 times, resulting in late arrival, rental car place gave car away resulting in increased BS charges because I was late. Frontier blows.
