3 hour delay. Had to change plans and was still delayed.

3 hour delay. Had to change plans and was still delayed.

The flight crew was extremely rude and especially not helpful when our flight was delayed.

Delays delays delays. Late taking off, late landing, wait for a gate, etc.

First time traveling on Southwest since bag fees were implemented. Usual good service. Just more expensive now.

Plane late from DC to Austin 30 minutes. Crew made up much of the time enroute to San Diego.

Our first flight was so delayed that we had 10 mins to board the next one. We requested if the flight attendant could allow us off there plane first and they denied our request even though I have seen this done before. Luck was on our side that we didn’t miss our next flight.

Everything was great except for the in-flight wifi that wasn't working.

It was great! The new boeing has much more space and charging ports!

Took a little longer than normal, but the process is clear and easy to understand.

Baggage check in would have been better if the service clerk told the other clerk that she was merging her two long lines of customers with her line so she could move luggage. Instead she only told the customers. When I told the agent and ask if she could direct who is next in line so we weren’t trying to cut in front of each other she said it’s not her problem and she can’t work three lines. I was shocked. Understood that they were working more than their share but some organization so the customers aren’t getting upset at each other would have gone a long way

Gate agent rushed to fill hot jetway with crowd so it took over 12 minutes to go from gate to plane. Just like a discount airline Pooly prepared cabin and third time that claim of rough air prevented any cabin service. Friends on a Southwest flight at similar time had service.

Not a "Delta" issue, but a JFK issue: We booked a connecting flight with 3 1/2 hours between to clearn immigration and customs. Our inbound flight (BCN to JFK) was on the taxiway 45 minutes which ate into our layover time. Immigtration was insanely quick with the CBP MPC app; however, clearing TSA (again, after we were ALREADY cleared in Spain on the inbound international flight) took over 95 minutes. This left us with 10 minutes before boarding the connecting flight (JFK to SAN) to walk to the far end of Terminal 4 and try to find food. We didn't find any food that could promise to serve us in under 10 minutes so we boarded the Delta flight after coming off a plance and an 8-hour flight knowing that we wouldn't be served any food on the next 5 1/2 hour flight. I feel like Delta needs to put pressure on the JFK TSA to open more screening stations (by our count, we saw only 5 scanners open and a line of - as we said - over 90 minutes. The insult is that we WERE ALREADY SCREENED through TSA, but as you come off one flight into the USA, you have to go through the whole process again. It seems like if you have a connecting flight, there should be a way to pass through immigration and customs without needing to return through TSA.

Rough day of travel all the way around. Wrong info given to us multiple times and mistakes in their booking making our trip 10 hours longer than planned. I’m bummed because I fly Delta all the time and love them. Mistakes happen. Just bummed that this was a rare trip our whole family was traveling together.

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Was a great smooth flight from Detroit to San Diego.

The boarding process was terrible especially with an indirect flight Chicago to Seattle to San Diego was terrible talking about we overbooked a flight idk if I’d take this airline ever again we got off our flight from Chicago to Seattle and we traveled for business and they told us our connecting flight was over booked and their was no seats asking people to take a delayed next flight and they don’t tell anyone coughing to wear masks seats 30A-B were terrible during the flight no one wants to sit next to people coughing all around I don’t want to be sick traveling for work or get sick anytime it’s very upsetting the staff doesn’t take this stuff serious to tell them to wear masks when they see people coughing and sneezing

They made us check our bag…. Even though there was plenty of space up top… and then proceeded to shatter by brand new luggage 😞

Food could have been better. A little more leg room would have been appreciated.

Delayed for mechanical and no updates on what was happening and how long the delay might be.

We are too tired and frustrated to comment politely at this point

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.

The service and food needs to improve to catch up with other international flights

The flight crew was fantastic! Which the seats had a small TV.

also wi-fi never worked attendant said satellite coverage is spotty over water ..... but we were over land!

They attended to my needs as I couldn't walk and they provided a wheelchair for me.q

This time my flight was smooth and uneventful. They started boarding even earlier than it was scheduled. I was pleasantly surprised. Thank you!

Boarding was a mess - the agent basically called every group in rapid succession, so there was no organization at all. The economy seats are a joke, and main cabin extra seats were sold out when I purchased my flight. As such, I was locked in the same position for four hours. Being 6’6”, it was impossible to get my bag out from under the seat in front of me, and I couldn’t have used my laptop even if my bag were accessible due to the minuscule seat pitch. Also the wifi was broken. American is a joke - can’t wait until they merge with Spirit.

Cons: "Just seemed chaotic. Plane super late departing. Baggage pick up was a nightmare."

Terrible. The canceled my entire flight when I requested a refund for a trip frontier canceled trip one way.

i was unable to check in the flight. refund requested

Great for the price. No wifi or entertainment, but gate agents and crew were fantastic and we boarded quickly and left on time.

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

I went to the Frontier counter in San Jose at 1030am or so on Sunday 10/13/24 to see if I could get an earlier flight to San Diego in lieu of my reserved 630pm flight. One thing led to another, and I was able to obtain an open seat for about $ 56. on the earlier flight. Fine. Then the agent asked if I "was checking a bag". Not knowing that carry-ons cost extra per Frontier policy, I thought that she meant a regular checked bag. Therefore, I said no. Once I got to the gate, the same gate agent who sold me a ticket told me that I had to pay $99 for a carry-on, and that all bags were extra on Frontier. Having never flown on Frontier, I was not aware of this. Part of the issue was that she was not a native English speaker, so there was a miscommunication as to what "bag" meant. I would have preferred for her to have clearly let me know at the front counter that any bag including a carry-on cost $99. It would have had the same outcome, as I had to take my carry-on. But it got hectic at the last minute at the gate itself. The baggage policy should have mentioned "including carry-ons" when we first spoke.

Literally everything could have been better. Why are the planes always late?

9hrs delay and didn’t provided anything until after flight landed $75 voucher for fiuture travel no meals or anything.

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

The truck that was refueling the plane drove away with the hose still connected to the plane and ripped part of the plane off with it

The boarding time. I was in Section 1 the lady in charge just let people in section 3 without see us. Make a line , I have to step out and ask her. We were in the line and she just take my ticket and that’s it, so if I don’t ask her she could leave us at the end! We paid more for that privilege and. She doesn’t care….
