Worst service- attendants dont want to help and sat us in front of bathroom

Worst service- attendants dont want to help and sat us in front of bathroom

Have not had a flight out or returning to Norfolk that has not required maintenance, and a gate delay. Properly staff the crew so maintenance can be performed without last minute emergencies on each flight and there is enough staff to have gates prepared for inbound flights. Staff to ensure the safety and on time service vs. profit.

Always pretty good as far as I see it. Staff was friendly and process was quick to get on and off.

Our flight was great with an unexpected upgrade. However, four days into our travel we are still without a piece of luggage. The bag tracker has not been accurate, the airline is not communicating with me or the luggage delivery service and no one is willing to take responsibility or guarantee any kind of support or reimbursement. Unfortunately, we do not have the option to easily shop to replace items as we are currently on a cruise. I have been very disappointed by United Airlines response.

There could have been better food options in economy on the long 7hr trip from IAH to AM.

The seats on this flight weren’t as comfortable as we had expected. Even leaned back these seats left us feeling crappy in our backs. Also we had to use our own tablets for movies, but nothing in the seats in front of us to hold the tablets up.

It was a short, comfortable flight. It did leave an hour late due to the pilot having to be replaced (family emergency) but that didn’t inconvenience myself & my friend. The situation was explained, eventually.

First class ticket gets you a choice of chips or nuts. . Just like economy Southwest. Also no screen in the seats. This is first class???!

All of the United employees I interacted with were professional and courteous. The aircraft was clean, the food on the flight was good. No complaints here.

Late boarding by three hours. No Wi-Fi. No screens. Cramped seats. Sitting on the tarmac for 30 minutes after landing waiting for a gate. Delay in luggage getting to baggage claim.

Initial flight had an engine overheat - returned to DFW. Had another plane ready, but crew timed out. Had to wait 5h for boarding. Fully boarded and pilot says plane is not flight worthy. Deplane and go to the other end of the terminal. Wait an hour to board third plane because the crew couldn’t leave the second plane because no wheelchairs were brought to remove passengers. Finally take off and there is no catering (in flight service) even in first class. Very much an AA failure.

WiFi didn’t work the entire flight. Very disappointing. Minimal food and options - sadly the state of current affairs. All other aspects of the flight were fine.

Given it’s a red-eye into Charolotte, we didn’t get any food. The survey does not include “N/A” so the rating will be skewed.

It went up and down at the right time and place. I’m happy with that outcome.

Flight was cancelled as I was in line for security. Next available flight got me to my destination 24 hrs later than the first. No refunds offered, just credit toward another flight. I booked with delta, got to my destination only 2 hrs behind my original flight schedule. Won’t be using American again.

It was a good flight - not overbooked and in time.

It was perfect in almost all ways. In fact it arrived early in both legs of my flight. The entertainment was marginal, but that was due mostly to the length of the flight. I love American!

Thankfully no connections off of this one on the day of the flight as it was delayed 90+ minutes.

Average - flew with Jet Blue internal and it was far more comfortable and better food and entertainment. Notable difference

Flight was delayed an hour. The pilot said we could deplane but that we wouldn’t be able to get back on. Luckily, my layover in ORD was 2 hours and it didn’t affect my connection. But a lot of people missed their connection and a handful of people elected to get off the plane. There were a lot of upset people and the American crew didn’t seem very sympathetic or accommodating.

The flight was great . But you only had one vegan item on the whole flight and someone prior to me took it . I was so disappointed cause I came in from the flooded area and couldn’t pick up anything prior to my flight .

I really didn't like anything. Paid for my checked luggage online ($79) and then was told that I would have to paid another $79 for my carry on. Was not allowed to enter the terminal until 3 hours before my flight and when I finally was allowed to check my bag and enter, my flight was delayed 3 times. When I finally landed, we were all instructed to "run off the plane" as they had to do a quick turn around to Las Vegas. Me and several of my flying companions will never fly Frontier again.

I paid for the upgraded bundle. Was worth it! Great experience round trip!

Decent clean onboard experience. Okay discount airline experience. Unfortunately, any customer service interactions are difficult and unhelpful. There is no service. Also, a premium seat only gets you premium boarding if you line up first. Once they start general boarding you must go to the back of the line. Not very premium

The delay was ridiculous because nary a word escaped from the gate attendant regarding our flight status. It was a complete joke.

Plane was down graded and I lost my uncharged exit row with more leg room. No mention or offer of refund from podium. Flight attendant was nice to explain this happens often and that I could request a refund via online form submission. I did this and have heard nothing back.

Although we received an email from Kayak AND the airline, turns out we were not on Frontier’s manifest for the flight. We had to purchase tickets at the gate. Not sure where this transaction fell apart, but it did. We are now disputing the charges for the SLC to PDX flight originally booked through Kayak.

Our flight was cancelled and I spent $800 on a replacement ticket. No refund was awarded other than the cost of my original Frontier ticket. unacceptable...

The worst experience ever!!! They canceled our flight when we arrived at the airport to check in. We asked why is it canceled they told us they don’t know. No apology, very cold and rude. We had to pay for another night at the hotel, we had to call out of work. We won’t be using them anymore in the future!!!

Flying Frontier was a nightmare. From the booking through Kayak, checking in, departing and arriving, I will never recommend Kayak or Frontier.
