The morning calzone was less than impressive and we ended up with heartburn

Some of the passengers are coming on board with luggage so overstuffed and/or too large that have no business going into the overhead bins.

I am in a wheelchair The gate agent knew exactly how to boarding A wheelchair first also the flight attendant knew exactly what she was doing

There is consistently no communication/updated time slots in the app on when a flight will board when its delayed, which is the most frustrating as a consumer trying to understand if they need to get food now, or if there is actually a chance for them to eat during their layover. This keeps being my experience with delta and a potential reason to change airlines.

Long delays at both DCA and MSP; Crew did not keep us informed (or very little). Airplane was showing signs of heavy use (not up to Delta standards). Food options for Business Class have dropped in quality. After landing we sat on tarmac for maybe 25 minutes with no provided chance to use the bathroom and crew did not tell us what was going on or give an estimated time to expect to be at a gate.

Both of my flights to and from JFK experienced significant delays. Most notably, my first flight was delayed by six hours due to crew members being affected by delays on a previous flight. While I understand that disruptions can occur, Delta’s staffing and operational planning should include sufficient contingency measures to handle situations like this rather than placing the full burden of those delays on customers. Additionally, the $12 meal voucher offered as compensation was inadequate, particularly given the high cost of food and beverages at the airport. Considering the length of the delay and the substantial inconvenience caused, I believe more meaningful compensation would have been appropriate.

Although I know the Airlines cannot control the situation when there’s a ground stoppage, it would’ve been nicer if we would have had more up-to-date information clarity around the delays. Additionally, I think the delays also took a toll on the Cabin crew, particularly the lead flight attendant in first class. She was not very friendly when we boarded the plane for many of the passengers. Number one she refused to hang a garment bag in the front closet for a first class passenger, she was unwilling to dispose of an empty bottle in the trash as I was boarding (despite drinking a bottle of water herself and needing to disregard), and she was very combative with a passenger, who needed to access something from his bag that was Gate checked. Frankly, it was really unfortunate as I’ve never seen a flight attendant behave that way directly to the passengers, particularly when none of us had done anything wrong.

Overall Delta was amazing from automatically booking us on the next flight once we missed our connection due to a delay to the constant communication throughout the entire process. We will continue to fly Delta going forward more and pay a little more if needed.

Nothing unusual. It was fine. I hate having to pay extra for my seat.

Didn’t make the flight. My connecting flight was an hour late and I missed the flight. You rerouted me thru Atlanta and I arrived in Rome over 10 hour after my original Rome arrival time. You also left my luggage in Atlanta and it took you three day to get my bag to meI spent 4 days in the same cloths, I had packed my prescriptions in the lost bag and went 3 days withoutMy heart meds.

The back to back mechanical delays from Denver to San Diego and then on my return flight from Denver to Great Falls it added extra time both ways

Really old place. Not as clean as it should be, tray tables needed better cleaning. The items, trays and some other items need to b6 engineered. Anything task you or crew may do is incredibly load, seriously engineer for quiet smooth, easy. Just opening and closing the tray table is actually dangerous and can easily injure a finger. I'm sure it happens as it happened to me! First time I used United and likely will be the last!

Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

Improve the food offerings and cabin seating. My wife would prefer to fly another airline, even with a connection for a more comfortable trip. A 737-8 should not be scheduled for a 6 hour segment, which turned into 7.5 hours due to the origin ground delay.

OK, I don’t expect much from coach class. Everything basically is pretty lousy. But at least I expect my bloody luggage to get from A to B. Tap Airlines lost my luggage and it has been more than 24 hours in Lisbon and they still have not located my luggage. On top of that, they are incredibly unhelpful. They feel actually dismissive. This lousy customer service.

No complaints other than luggage carousel was incorrectly guiding passengers to the wrong carousel on the screen.

The flight crew on this leg of my trip was very friendly and pleasant. Every one of them was humorous, as well as helpful and accommodating. This group was BY FAR the best crew I’ve flown with. They deserve kudos.

Food was poorly timed and not good.. Hand held snacks, really. I kept asking for water and never got any. Service was rushed for a 7-hour flight.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

The amount of seating is ridiculously small. Three points to consider Point One: Your in flight magazine needs to be smaller. Do you realize I can't even hold it in a reading position because of the limited space in front of me? It's a hangover from the past and if you want anyone to read it, it must be smaller. Point two: It is very uncomfortable for a lady to be sitting next to a strange man and constantly rubbing upper arms even when both of our elbows are within the arm rests. And larger men (whom I pity in this confined predicament) also tend to spread their legs into my leg space which requires me to hold my legs into a smaller position. Point three: The seats seem to position one's body in an unusually upright manner and the head rests push the head farther forward. I gave a small effort to see if the headrest could be removed but didn't want to break it or cause a scene with my efforts. I finally put my jacket behind my back to place my body more forward to match the head rest. The service was fine and I noticed ALL staff worked at smiling and greeting passengers. That was nice. No one likes to fly anymore as it is an endurance rather than a pleasure.
