Delta always provides stellar service. I am always impressed and will try my best to travel via Delta if I can afford it.

I think in the future I cannot fly anything less than Comfort plus. The seats vary depending on the plane. The people are extremely nice and funny. I try to only fly Delta if I can help it.

Great flight. Thank you for the upgrade to first class.

Everything was great. The only thing that wasn’t was the breakfast calzone which was basically warm bread. It was very tasteless and wasn’t good at all

I usually like delta. However this is my second flight that the wifi does not work

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.

Crew was great. Near on time departure and early arrival. Snacks are always meh. Not a fan of the "pay for everything including miles " proposal unless base flight rate going to be 100 bucks.

We had a lot of really rough weather but that was not Delta's fault. Pilot was amazing.

The boarding process needs to be refined. Sometimes the gate crew call out the boarding zone, and then flip to the monitor to show which zones are boarding. So unless everyone is gathered around to see the monitor there is usually confusion as wi which zones are boarding.

The young man who was our flight attendant in first class was lazy and did not do his job well at all. Never offered drinks upon boarding - actually I take that back... said "are you okay with water" as if I do not want to get you anything else, only passed the snacks around once, got my drink order wrong and then never offered a second round of drinks. He was the worst I have ever seen on Delta and we fly a lot.

Fantastic experience once again flying with United! There was great communication from the cockpit and one of the flight attendants went out of her way to get my two little kids some special treats which elevated our travel experience coming home.

Flight attendants need to know their plane. Seated in first row yesterday. The seat had about a 1 inch recline that was not adjustable. I don't appreciate being awakened to raise a seat that can't go any further forward and such a small recline is either irrelevant or the plane needs to be repaired. Not the way to treat any customer and especially the ones who have paid that level of money for the seats.

Flights was great, service and transit support was outstanding - but the food was limited and of poor quality - only a snack on the first hour for 2 hours 1/2 leg. and a light breakfast on the second 4 hour leg.

typical but they have finally enhanced the wifi on some UA flights. Boy, its such a huge improvement

Return flight was perfect. All on time and no hiccups. However, going was another story. I don't blame United for the weather, but I am rather disappointed in its response to my getting stranded in my layover city for the night. United gave me a $20 food voucher. That's it. But besides this policy, the employees were incredibly helpful rerouting me to my final destination in Fort Lauderdale, FL. So overall, 8 out of 10. 10 out of 10 for flight comfort, inflight service and before flight service. 5 out of 10 for layover handling.

The price. Omg $1100. Was crazy and it was not clear on the website.

Delayed too much. 1.5 hrs in the airport and another 1 hr in the runway. Got too late in the night. There was no proper food available.

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

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?

WiFi was slow as compared to trip down. Maybe because it was a night flight and more people were using it?

Seats were very tight for a 17 hour flight. Baby cried for 15 out of 17 hours.

Good flight, excellent personnel; poor comfort, small seats, big cost.

This trip on American was the WORST I have ever experienced. The plan was LATE taking off from Tucson due to mechanical issues. It caused me to arrive late in Dallas, so I tried to move flights so I would not miss my dinner meeting. First attempt, that flight was delayed, Second attempt, that flight was also delayed. Got back on original flight, the mechanical issue was NOT fixed, so we de-planed and had to find the new gate. Overall, was which was 4 hours delayed and missed the dinner meeting. Friday return, flight from Orlando was on time and landed early. Then the next flight was delayed due to crew coming in late, and them waiting on other passengers. After 90 minutes of delay, we boarded, and then were informed the Fist Officer could not fly due to time constraints. At 12:15 AM we were offered a hotel for a 4:20 boarding flight. Not happening. DFW was COLD and no place to sleep. Plane delayed again to 6:50, but was late taking off AGAIN. Finally landed in Tucson at around 8AM. Should be refunded 75% of the ticket costs due to negligence, nothing more.

Cabin was bone dry, no humidity whatsoever, and pretty warm; and beverage service didn't start for at least an hour. I had to go to the back for water and the FAs tried telling me it was always this way for all Miami flights, which is complete nonsense. Avoid the MAX8 like the plague.

Im sitting here waiting over an hour for my golf clubs

Flight was 2+ hours delayed and they “misplaced” all 3 of our checked-in bags.

Overall, really good experience, on time and the comfort was there. Wi-Fi was easy to connect

Flight was delayed 5 hours only to be cancelled at 1:30am. I did not get on the rescheduled flight because of worry it would be delayed (which it was). I needed to drive home. Horrible.

When there are many passengers who are going to miss a connecting flight, they always say please let them off first. But the flight attendant never manages that part of the process. It would be helpful if they would repeat that and stress that to the other passengers.

I have never been assaulted they way I was today in Charlotte - shame on American
