My flight was so delayed I would’ve missed my connection and had to cancel my trip

My flight was so delayed I would’ve missed my connection and had to cancel my trip

Seemingly unnecessary delays were compounded by a lack of communication from the flight crew which turned a four hour delay into an overly stressful experience.

I like Delta. I dislike the volume of announcements from the crew. They are not always easy to hear and typically repetitive.

I think the crew makes way too many announcements that are: 1) hard to hear in some cases and 2) repetitive. This detracts from entertainment and concentration if working or reading.

Great crew. Comfortable seating. Nice overhead bin space. My app didn't allow me to check in for my flight to BOS. When I called Support, they didn't fix it, but just told me to check in at the airport. Seat back entertainment was great. Could be better if the audio could connect to Bluetooth.

It was the hottest flight I’ve been on in a long time. The female flight attendants were not nice.

I'm 6' 2" and even in economy plenty of leg room

Flight was very delayed so I was able to get on an earlier flight via stand-by. Crew communicated effectively around delay and worked to make customers comfortable. Wifi was ok, streaming TV was great. App functionality broke down once I was moved to stand-by on earlier flight.

I missed the flight because the Minneapolis flight was 49 minutes LATE, and the Boise flight LEFT 24 minutes EARLY!

Having to up charge for a seat assignment is not good. Delta can do better

Santa Barbara is a super small and easy airport. Breezed through rental car return, breezed through Security, ordered a coffee and muffin and to my gate in less than 30 minutes. Maybe because it was a small airport we got the oldest plane. Hardly any overhead space and absolutely zero internet. Its NFL Sunday man! That hurt.

We were delay because so many bags needed to be gate checked and it was disappointing not to have outlets in the seats for such a long flight.

There were no vegan options for first class. Even though we were promised the satellite internet for free, we received NO wifi at all. Even though we were promised a 20-min early arrival, we ended up over 30 mins late.

No water or beverage was provided. I had to ask for water. The sole flight attendant had more interest in selling the credit card. In addition when we got to Dulles the plane and gate were misaligned and it took at least 15 minutes to get off the plane.

Raleigh to Chicago was OK. The problem was Chicago to Lincoln. Flight was delayed 4 hours. Give them credit for the updates and reason why it was delayed

Flight delayed over an hour with plane on runway because of weather in an area of the country we were not in or flying to.

Flight was delayed almost an hour because the cleaning crew broke one of the bathroom doors.

Comfortable seats and good crew. There should be some breakfast options in menu for economy class to purchase Wifi was not working in the flight

Why wasn't this flight departure scheduled eith another crew so that it could leave on time? When we arrived in Denver we had so little time between flights we had run to the connecting flight. We should received some credit for the inconvenience.

My flight was 3 hours late, which caused me to miss my connection in Denver. Further, this connecting flight was then Later canceled. This required me to stay another night an hour and a half away, and rent the rental car for an additional Night. I am still waiting for United Airlines to reimburse me for the inconvenience and Expense of having to extend my rental Car for An additional Day.
