Pros: "The staff were lovely."
Cons: "no covid-19 precautions were taken. It was a packed airplane didn't feel comfortable"
Pros: "I appreciate that Delta chooses customer safety over profit by not packing flights and continuing to social distance."
Pros: "Precautions taken appropriate"
Cons: "Environmental controls, it was a little warm. Seats seemed more uncomfortable than usual. Air vents, lights, too far from aisle seats."
Pros: "Everything from hospitality to the ease of the flight. Captain communicated to put all at ease during this time in which this pandemic has gotten many fearful of flying. Great landing as well."
Cons: "Everything was great!"
Pros: "They left the bags at LAX. We we’re driving to Sun Valley and don’t have our ski clothes and equipment"
Cons: "Get our bags to us in the morning"
Cons: "DTW to FLL, plane was delayed coming from BOS to DTW 5 hours for BOS weather. The plane arrived & they announced they would turn it around ASAP. They started the boarding process & then stopped it stating that a crew member had timed out. Delayed hour to FIND one. Shortly after delayed overnight."
Pros: "Inflight entertainment was the best I’ve seen in coach. Free games, movies, moving map, etc."
Cons: "The seating is too cramped. It has just gone past what is reasonable. Seems too tight on both the knees and elbow room."
Pros: "Crew was very kind and entertainment was good when available"
Cons: "WiFi in all flights"
Pros: "Seat was decent and only a $10 upgrade. Worth it!"
Cons: "Wasn’t clear what boarding group was up. I don’t usually fly delta so maybe I’m just not used to the system but something on the video screen at the gate saying where they were in boarding would have helped. I wasn’t the only one that seemed lost."
Pros: "The Crew on this flight was great and the flight was quick."
Cons: "The flight was delayed 3+ hours and Delta kept pushing the delay out further without giving any updates as to why it was so delayed, and when I inquired at the Delta desk at the gate the woman was very rude to me as she snipped that it was a mechanical issue."

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

Pros: "Had an exit row seat, 17D. Lots of leg room."
Cons: "IFE was not streaming movies, WiFi on but not loading"
Cons: "After the flight was diverted due to Weather conditions I missed my connecting flight and American Airlines did a terrible job handling the changes and assisting their customers at DFW airport."
Cons: "Delayed 1.5 hours each way for maintenance, did not allow us to switch seats to sit together previously at flight and the flight was very empty. Very uncomfortable seats. Will not fly AA again"
Cons: "The seats were tiny! I'm a big woman, but not a huge one and I struggled to get my belt on. Considering how nice their seats are, this is one of the smallest seats I've ever sat in!"
Cons: "We waited in the shuttle bus for one hour while they determined the plane needed maintenance and found another plane to warm up"
Cons: "Baggage handler lost my bag, grabbed it off plane cabin, never found"
Cons: "Too small of a plane for that long a flight. Cabin was too damn hot."
Pros: "The early boarding and charging ports accesbility?"
Cons: "Just one snack option maybe a few more comps. Also it didn’t have any info on the new airplane. The ride was nice."
Cons: "Super small and crowded flight, no safe distance whatsoever. A particular older flight attendant was cranky."
Pros: "Very friendly crew."
Cons: "This is a small airplane. I would like to see United insist that people check large bags."
Cons: "This was the most uncomfortable flight I have ever had. The plane was so hot we were sitting there sweating the entire time. It made it impossible to sleep or focus on a movie or anything, and it made the flight feel 10 times longer."
Pros: "Leg room was good in economy plus but no entertainment. Flight ran on time though."
Cons: "WiFi was broken and only refreshments offered! No meals for purchase only snack boxes that were horrible."
Pros: "The 737-900 was good and loading seemed pretty fast. The gate agent was very friendly and genuine."
Cons: "Weather delay, then an aircraft change due to that, and finally an additional 20 minute delay due to a late crewmember which was not fully explained. If the crew member had also been deleted by the weather I would not have felt so bad about the additional delay."
Pros: "made it home safe"
Cons: "Boarding protocol. we were traveling together and were placed on opposite ends of the aircraft. very cramped seats. would prefer not to fly them again."
Pros: "Nothing was good about this airline with the exception of the baggage crew that finally helped me in Washington Ronald Regan Airport"
Cons: "My flight out of Portland was canceled and it took hours to rebook. I had to fly American Airline to Washington DCA where I roamed the airport at 9pm looking for someone from United. The crew in Portland ME told me the gate person would have a hotel for me.... The baggage crew had to help me."
Cons: "I only made it as far as Chicago, and my bag was fairly comprehensively lost as I did so"
Pros: "There was no in-flight entertainment. I like when the planes have the TV's so you can watch."
Pros: "Flight attendants were exceptionally great! Gave out free drinks and snacks for no reason."
