Cons: "Flight was delayed almost 3 hrs. Ran out of food right before my row. I upgraded my seat but feel I got the short end of the stick."
Pros: "Good crew, kind and hard working staff. It is so nice to have inflight messaging and that was a pleasant surprise that made the flight go quickly."
Cons: "I found the delta app to be less user friendly than the United one. I wish the in flight entertainment were in the Delta app versus downloading yet another app."
Cons: "After my flight was delayed for over 3 hrs - the counter clerk was rude and unhelpful. She felt it was appropriate for her to flick the customer service phone number in front of my teenage daughters. I would say avoid Delta!"
Pros: "Quick flight"
Cons: "Coffee or beverage service would have been a nice touch."
Pros: "What did you like? Decent meals, no charge for cocktails, blankets, pillows and head sets for everyone, friendly flight attendants, excellent entertainment options."
Pros: "Amazing service from crew"
Pros: "Entertainment on short flights is a nice surprise"
Cons: "Very very late.. I almost lost my replacement of the replacement of my connection. Had to run like hell. The luggage didn't make it. To summarize the day, woke up too early, got to my destination hours late and got the luggage in the middle of the night."
Pros: "Great service"
Cons: "Stuck at landing. For over 20+ minutes"
Pros: "Cabin crew super helpful & friendly. The food was great - all snacks & meals were well prepared and had great flavor, I’m not saying it’s a 5 star restaurant, but I was wasn’t expecting the quality we received. Great job! Impressed by Delta service."
Cons: "Traveling is always a challenge - abundance of patience required! We traveled from Dallas, Atlanta, Amsterdam, to Rome & back. Every country had a little different process for boarding and getting around - most had friendly staff, on point, helping clueless, stressed, & frustrated travelers. I was really disappointed in Atlanta, not a very welcoming or helpful spirit for visitors to US - not all (80% were awesome), mainly those trying to greet and direct through customs. Most hate the arrogant America anyway, don’t make it worse - put your best people on the front lines to help with international relations & show why the US is the best. Put those that don’t want to be here loading bags out back! Sorry for the lecture, but this is any business!"
Pros: "Very friendly crew with a clean plane!"
Pros: "New plane with great entertainment arrived 30 mins early"
Cons: "The flight dely 1 hour"
Cons: "Surrounded by screaming kids, screaming adults and no AC"
Cons: "Seat wouldn't redline."
Pros: "Weather kept them from being able to serve everyone but she did pass around cookies which was a really nice thought!"
Pros: "Food was good and so was the movie selection"
Cons: "Boarding was slow and the interviewers were disrespectful. Also I was upgraded last minute and I could never understand the system by which upgrades to first class are granted. Just because I used my points to buy the flight I wasn’t eligible for an upgrade to the one seat left in first class even though the flight is full and I am the first one on comfort+ upgrade list and there was no one on delta one upgrade list."
Pros: "In flight tracking"
Cons: "Irregular serbice"
Pros: "The crew"
Cons: "The delay"
Pros: "Movie selection was great!"
Pros: "The flight is short"
Cons: "Delayed from 930pm to 6am. Didn't tell us till almost midnight. Because of scheduling issues not weather or anything. The check in people had no idea what I was talking about when I tried to check in for my 6am rescheduled flight."
Pros: "The seats"
Cons: "We purchased tickets together and our seats were not together when we checked in. We had one small roller bag for the two of us and we ended up having to gate check it along with 3 other people and then there was clearly enough room for it once we were boarded."
Cons: "Pasta on board is heavy, lighter meal option is preferred"
Pros: "Even though one couldn't hear an announcement Delta did have a staff person tell people where to line up for different zones. Flight was fine and on time."
Cons: "Couldn't clearly hear any announcements and once it was getting closer to boarding time as usual so many people just start gathering in a mass. (It would be so much easier to have signs label Zone 1 ,2, etc.)"
Cons: "Poor WiFi. Paid extra to get it, but didnt sporadic at best."
Cons: "They charged $300 for 3 bags"
Pros: "Super quick"
Pros: "On time departure and arrival"
Cons: "We landed at 2:14 p.m. but did not get our luggage until 3:38 p.m., with "priority" because we were traveling business class. Dozens of bags that were not "priority" preceded ours."
Cons: "I don't like that I already completed this survey several days ago and have been receiving reminders to do so. I guess you don't have a good system in place for knowing who has and has not completed your surveys. That's too bad."
Pros: "Able to download boarding pass into apple wallet"
Cons: "Flight was almost an hour late departing, bag is a carry on but storage too small to keep bag, then wifi didn't work the entire flight. Had to run to our connection since our layover time was taken up in Boise. If we had missed the flight, we would have been re-routed to another airport over 1 1/2 hrs away since ours closes. Next flight was not much better, oh and wifi did I t work on it also - last 3-4 delta flights I've taken have been late and didn't have working wifi - starting to think their system doesn't work at all - seriously going to take any other carrier but Delta going forward"
Pros: "Let on time and arrived 30 mins EARLY."
Cons: "Had to pay for meal despite length if flight."
Pros: "Flight crew were friendly and engaging."
Cons: "Delta customer service- terrible when I called about reservation. Agent upon arrival at airport clearly not happy about 5am shift."
Pros: "Everything about it was excellent, which is saying a lot for a guy who travels a lot."
Cons: "I realize that a flight attendant is there ultimately for safety reasons, but one of the three was particularly brusque in her interaction."
Pros: "Crew were lovely, boarding wasn't too painful."
Cons: "Payed extra for a seat that was the seat I selected. Totally disappointed"
Pros: "I got a seat in the exit row with lots of leg room. The entertainment that I didn't use offered a great selection with very recent movies, etc."
Cons: "I didn't like that I had to take a bus to my terminal. I didn't like the fact that my gate was changed more than five times. I didn't like that my flight time was changed more than 15 times with no reason why until boarding time. I didn't like the fact that I did not get a seat assignment until boarding the plane. I didn't like the fact that they couldn't manage to scramble another plane and crew, but instead forced us to wait over four hours for one that was stuck somewhere else in the country."
Pros: "Staff were all polite"
Cons: "The least amount of legroom I've ever had. The most cramped I've ever been and I'm 5'2 and fly a lot. Also for a 5 hour flight, I should not have been as uncomfortable as I was. There's less cushion than before."
Pros: "Friendly but efficient. Allowed me to keep my bag with me without a fight."
Cons: "Flight was delayed substantially. Sat on the plan 40 minutes before taking off after already being 30 minutes delayed."
Pros: "Excellent trip. Provided ample food snacks and drinks."
Pros: "GRU to ATL to LEX - all was fine. The plane from GRU to ATL was one of the nicer jets I have ridden in. The ratings above reflect my overall trip of going to Sao Paulo and returning to Lexington, even though the first part had to be re-booked on United."
Cons: "LEX to ATL to GRU did NOT happen because the LEX flights were delayed to the point of missing the ATL connection. While Delta re-booked me on United, my flight arrived 3 hours later than scheduled (so transportation plans had to change), my bag did not successfully move from the Delta flight to the United flight (and was thus delayed in getting to GRU) AND once the bag was received, 4 shirts had been stolen. While a delay/theft claim has been filed with United, this could all have been avoided if the Delta flights had been on time."
Cons: "The original flight was canceled and a new one substituted - basically they wanted to fly a smaller aircraft (via a different regional carrier) so the flight number changed. PHL did not have the new flight info displayed at the Departures board or on the screen at the gate. Caused a little anxiety."
