J
2.0 Poor
Terrible - the flight was delayed taking off after boarding. Then the flight circled lga before landing. Significant delay
S
6.0 Okay
I booked a round trip with Delta, and each of the four segments was sold off to three other airlines. All four were late or cancelled, so I had to troubleshoot with three different airlines, NOT Delta. In fact, even though I had paid money to Delta, they could not help or troubleshoot anything. Not nice.

6.0 Okay
The crew performed the absolute minimum. The plane ran out of toilet paper and there was 2 hours of flight left of an 8 hours international flight. The food was a average
C
6.0 Okay
The actual flight was smooth and we arrived earlier than expected which was great. The flight attendants gave unclear instructions and were rude. They seemed overwhelmed or flustered for the flight. Inflight service was delayed and unsure why.
R
8.0 Very good
Everything went smooth from check in, thru TSA, then boarding, and a smooth flight to ATL.
L
6.0 Okay
There were weather issues in the area apparently; however, that was not obvious from what we saw outside of LaGuardia. We were delayed leaving (which I understand); however, once we were on the plane we didn't leave for a long time. It may have been two hours?? - all I know is that we sat there for a long time with no information as to why we were not taking off. Finally, after 45 minutes to an hour (maybe?), the pilot gave us an update that no planes were able to go in the our flight path direction (or something like that) due to weather. There was nothing additional added. What does this mean? Why is this? What are the options? When will you give us another update? There were no updates for maybe another 30-45 minutes. There was no explanation as to why we couldn't be rerouted to avoid the weather. We had no information at all. We just sat on the plane (for about 2 hours) with very limited information. All I would have wanted is an explanation as to what was going on. Tell me there is bad weather coming our way. Tell me they are working to reroute us around it (which is what they did). Tell me SOMETHING.
W
6.0 Okay
Crew and support were very good; lounge was very good. Seat was narrow and very close to other passengers; lie flat is more complicated and exposed to the aisleways.
G
2.0 Poor
My 4pm flight did not leave until about 10pm. I did not enjoy this experience.
D
4.0 Mediocre
I had an extensive delay on my previous flight and we had another delay due to the crew not being there. We were scheduled to have a late arrival but due to the delay it was even longer.
