I’m on this flight every other week. Same flight, same day of the week, same time of day… Multiple times there are issues getting flight plan registered and FAA approved r to take off. PAPERWORK This is exhausting and it sucks.

I’m on this flight every other week. Same flight, same day of the week, same time of day… Multiple times there are issues getting flight plan registered and FAA approved r to take off. PAPERWORK This is exhausting and it sucks.

Flight Staff: Always great! Checking back vs carry-on: I typically check my bag since so much time is spent stowing the bag, it's heavy, maybe not enough room. Delta is charging $45 to check bags. Yet, the people who have multiple carry-on bags are then asked to check their bags and are offered this service for free. This does not seem fair to a person who is trying to be proactive in improving the process . Boarding: Boarding is always slow and exhausting. With the exception of First Class, Economy, why not board the zone in the back of the plane first??? Seats: Why cross the seat belts? I get that it looks nice, but people waste so much time moving them or sitting on them and then having to move. Seats: On both my flights the seat did not recline. Not a big deal. Smell: There was a horrific smell like the restrooms on my first flight. I thought I was going to be sick. Most flights do not smell great. Does Delta use air purifiers or anything?

The crew were very respectful. And also they were welcoming.they did help us locate our seats.i enjoyed.

Audio Visual Equipment lacking content and features. No connection ability for noise cancellation pods

DL482 did not wait for about 10 of us including a mother and 3 children when we were in the same terminal on DL486, where we were switching from waiting for a jet bridge fix, to moving to a neighboring gate. I understand taxiing delays are ok either but man. We only needed 5 more minutes. DL482 did not adjust from their times at all. This was my first time with Delta.

DL486 could not get to the gate due to jet bridge malfunction. We moved gates. The connecting flight of LAX to MCO was not communicated with. Even though we were in the same terminal, DL482 left without about 10 of us, including a mother and her 3 children. I got to the gate at 7:34 am which is past the 7:20 am last call for a 7:35 am departure. Had they waited 5 minutes, all of us would have made it on board.

Both legs on the way were smaller planes, each had a mechanical issue causing a delay

Delta exceeded my expectations! I am beyond satisfied. Thank you!

Flight was on time! That's the most important thing for me.

Delta did an awful job w logistics at DTW. Missed connection. We were there an hour early. SUCKED

It was fine for the most part. But the volume on the announcements was way too loud, and the cabin temperature was chilly. We had the hardest landing I've ever experienced- I think it hurt my back, and the tires squealed when we touched down.

Great, except the canon was so cold. Even the flight attendants put jackets on

Did not like the check in guy quibbling over a couple pounds at the luggage weigh in

Just having a little bit more legroom would've been nice.

This is related to my second leg of the flight, from Washington DC to SFO. I understand things happen, but I got home at 3 am for a 12:59 am landing. I live 10 min from the airport. Bridge breaks when a few rows of the plane are off? Maintenance didn’t catch that?

Boarding, time to take off, in flight offerings, and staff were all great. I recommend using UA for this short flight.

This was an auto-rebook due to being delayed from an earlier UA connecting flight. The boarding was fine, but they sat me in a middle seat when my original booking was a window seat. Overall, the flight was fine as it still got me to my final destination.

Both my flight where delayed Had 25min to make it to my transfer flight

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

DELAYED AGAIN and AGAIN and AGAIN - not only that, you delay in 20 minute increments for hours and hours instead of having an accurate delay understanding.

Sat on tarmac at arrival at DFw for more than 30 min waiting for a gate.

Both directions of our trip were befuddled by massive delays, one of which led to our connecting flight being grounded mid air due to storms that we’d have missed if we were on time. The other our originating flight was delayed repeatedly until it arrived at our connecting airport later than our final leg was even supposed to have arrived. American cannot seem to manage rebooking s for a family party… both directions we had to come up with a plan to get to Boston stay overnight only one night each direction was covered by the airline -and take a bus to or from our destination. Missed an entire leg of our trip, hotel cancellation fees, expensive stay in Boston and bus ticket expenses are unlikely to be comped and the meal vouchers are worthless.

My flight was 4 hours delayed on departure at 6a causing me to miss my connection at DCA. I had to scramble to find a seat home on a later flight and instead of an exit seat, I was in row 30 on a flight getting me home 5 hours later than planned. The AA team on the ground did a fine job. AA continues to run the airline like the passengers are cargo.

The flight attendants were very friendly, efficient, and helpful. The plane was ahead of schedule, and it all went very smoothly. Thank you.

I have a gluten allergy so did have any food

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

Wonderful crew and early arrival to our destination. It was so nice to have free wifi access and movies too. Thank you!

Flight was delayed after boarding and no idea when it would take off. Crew in Portland did arrange for transport to Boston for a different set of flights to my destination.

Seats are so close together. Middle seats should be discounted.
