There was no wifi available on this flight. And there were no screens, no onboard entertainment, no entertainment options at all. It was like travelling in the 1990s again, except without even a main screen for options. Seats, as usual, were tight and uncomfortable.

There was no wifi available on this flight. And there were no screens, no onboard entertainment, no entertainment options at all. It was like travelling in the 1990s again, except without even a main screen for options. Seats, as usual, were tight and uncomfortable.

Good seat comfort ORF to ATL. Bad seat ATL to SEA (terrible lumbar support, hard, ouch)..

Because I was moved to an exit row, the snacks in economy comfort, the selection of snacks was better.

I upgraded to first. Quick and easy boarding. Comfortable seat with power and a nice IPA.

Probably not the fault of Delta but there was delay after delay after delay and I ended up getting home 4 hours later then I should have at 1:30 in the morning

Easiest airport experience ever in my life at MSP with Delta check-in and flight attendant gave us a bottle of champagne in celebration of our 10-year wedding anniversary, so overall amazing!

No in flight service, no explanation - FC got service, C+ did not, unsure about Economy. No turbulence to speak of, so I guess another way to cut cost, or promote health and well being of Delta employees? Also, boarding in MEM combined zones, and with overhead space already full on both flights after Zone 2/ Diamond, presents a huge challenge to find a space for a bag. Delta, other than point A to B, is no longer reasonable to fly - very poor experiences, not even taking into account the chastising at the gate and rude crews, across the board.

It would have been better if the flight wasn't delayed by 2.5 hours

Delta’s staff is unmatched. From the gate agents, to the pilots, to the flight attendants… all top of the industry.

Delta flight Delay for ,more that two hours i.e original flight was 6.30 PM and it starts at 8.45 PM, When we connect Delta team for meal vouchers as it is late arrival in designation,But we did not get it as per delta policy , which is not good for mid night arrival,

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

Flight was late - I was downgraded from first class to coach

United overall experience is great these days. Airport experience was very organized. Staff on flight were great. App and information as good as it gets.

Great smooth flight. Had a seating change, but that was an improvement. Thanks United Airways Crew.

Flight was good but there are way to many announcements for credit cards etc.

Crew seemed a bit cranky. No seatback screens. But boarding was efficient and on time and we arrived early.

See previous note about the passenger in Denver who threw my husband's bag out of the overhead bin in order to maker room for his own. And the flight attendant back up the new passenger.

Terrible. They wouldn't allow me on my flight on the 14th..

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

This flight captain and crew were amazing, started ahead of time of departure and reached 30 mins before arrival time. Amazing!

Long delays, lack of information about the status of the flight. The flight was delayed 4 times.

Could we please end the loud announcements about credit card offers on your flights? We are trying to sleep, work, watch videos, etc. and if we need a credit card, we will ask for one. Flying is already not what it used to be.

I would like the crew to talk LESS over the PA and specifically about credit card offers. I am trying to work, sleep, watch a movie and the PA was booming about a credit card offer. Could we go back to the days when the customer was more important than selling a credit card?

Enough space,crew was helpful,food was good.The gates are way far especially for travelers with health issues

No enough space plus only allowing one laggage instead of two like other airlines.

There were no TV screens - even in Business class. 5 delays, and only given $12 meal voucher! Terrible!

It was good. But the gate team made me check my carry on when there was plenty of space for my luggage on the plane. Otherwise our trip was fine.

The entertainment options were at best, fair. It was exactly the same as my outbound flight. It would have been more entertaining if there were some series from Apple TV, HBO, Showtime or other carriers for me to catch up with.

Concern Regarding Significant Gate Delay and Jet Bridge Issue Dear Customer Relations Team, I am writing to express my disappointment with the experience I had on my recent flight AA 2414 on Sunday January 18, 2026. What should have been a routine departure turned into a frustrating and avoidable delay due to an issue with the jet bridge at the gate. As a result, the flight was delayed by approximately 90 minutes while multiple gate changes were attempted. The lack of clear communication during this period made the situation even more challenging. Passengers were left uncertain about the cause of the delay, the expected timeline, and the next steps. This not only disrupted travel plans but also created unnecessary stress for everyone on board. I understand that operational issues can arise, but a malfunctioning jet bridge and the resulting extended delay suggest an area where procedures or equipment maintenance may need attention. I hope you will review this incident to prevent similar disruptions in the future. I would appreciate acknowledgment of this concern and consideration of appropriate compensation for the inconvenience and lost time caused by this delay. Thank you for taking the time to review my experience. I look forward to hearing from you. Sincerely, Dion Dillard

Good for a budget airline! It was easy to get on, staff was really nice. Can’t say anything about the food or entertainment because it wasn’t available, which is fine.

I am writing to express my disappointment with my recent Frontier Airlines flight. I was charged $99 at the gate because my bag was said to be too large, yet once onboard there was no available overhead bin space, and I was required to place the bag under the seat in front of me anyway. This made the charge feel unnecessary and unfair. Additionally, before the flight even took off, I was asked to move from the seat I paid for into a middle seat so another passenger and her cat could have my seat to themselves. I was not offered compensation or an explanation for being moved from a paid seat. Between the unexpected bag fee and being forced to give up my seat, this experience fell well below acceptable customer service standards. I would appreciate a review of this situation and appropriate compensation.

It was costly and difficult to check in. $85 to take a small suitcase with me, carry on or checked and $75 on the return trip, Plus $25 if I didn't check my self in check in $25, because I couldn't do it on the kiosk. Small very uncomfortable seats, waited on the runway for near an hour each way. It was my worst flight to date.

It was ok. It was expensive to check 2 bags ($75.00 per bag), and then it took a long time to wait for shuttle to take us from one terminal to the terminal where the plane was taking off at LAX. And all of this for a flight where we had to pay for any food or drink that was not water.

It didn’t happen. I booked it and then was told it wasn’t available and then forced to pay far higher prices for a worse option

A 630departure flight Delayed 6hours! They changed my gate, I moved to the new gate. Had our flight on the screen for 12noon departure. I go get above to eat, check screen again and the flight was gone, no notice no announcement, nothing!! They sent my bag on the flight I wasn’t on, got it back to me 3days later. Thank goodness they did refund my money but I will NEVER fly them again.

Due to weather, my flight was delayed, further delayed, then canceled. I eventually got through to a support person who helped me find a different route out of MSP, but to get to DIA, they didn't want to, but eventually did help with the connection ticket purchase. But even this replacement flight was delayed time and time again, and I would have missed my connecting flights and I didn't want to get stuck in a layover city, so after 12 hours at the airport with two young boys who were very tired, we just cancelled our plans and spent the week at home, instead of Nana's.

Plane and crew on board were fine. Everything else was terrible.

The third party booking with cheapflightsfares was awful. Kayak should NOT partner with them. They sold me a bundle including seat selection and carry-on, but did not book the carry-ons with Frontier, so I’m out of pocket for $414 more while I await resolution.

This company socks. It's fraud. They canceled our flight yesterday, and today we were late because of a really long line at the check in bag. At the rebook station, there was ton of people. The workers were all rude. I am gonna make a report to FTC.
