The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

Best airline! Always friendly and welcoming. Skyclub was great and loved the fast free wifi on board. I also love that you can pre-order your meal on the app!

Atlanta boarding crew at gate were filled with arrogance and were disrespectful. In flight crew showed indifference to the needs of passengers. This is about the flight from ATL to BDL.

Boarding was somewhat chaotic. Unable to evaluate crew or food/drink because captain kept them seated due to turbulence. Have no idea if entertainment was offered.

The gate area was incredibly short staffed, with one representative manning 4-5 flights, which caused a 3 hr delay in boarding even though the plane was all ready to leave. Other flights also were delayed because of this. The flight crew was awesome and I feel bad for the only gate worker on call, but Delta needs to hire more employees.

Very frustrated with boarding gate crew. She announced the plane was small and they would be limiting us to one item to carry on. Not a problem for me as I understand the tiny planes have limited space!! Not the case here! It was a rather large plane and had plenty of room for bags! So because I don’t want to be one of “those people” who ignores the request to check a carry on I did so asking if I would be able to pick it up at the bottom of the ramp on arrival in Knoxville to which she responded “yes”! Then I watched as every other passenger held onto their 2 items and boarded!! Then when we arrived in Knoxville our 2 carry ons had been put with all the other luggage and we had to go to baggage pick up and wait for all the big checked bags to come off the carousel! So she lied!! Frustrating. Next time I won’t be so nice!

It was a good experience except when boarding a female flight attendant did not go out of her way to assist my teenage daughters in finding space for their carry-ons after their compartments were full.

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Flight delayed from Cape Town to Washington then got diverted to miami and in miami we had to fend for ourselves , im still trying to get to Shreveport now

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

Too many fees (but that seems to apply to all airlines nowadays)

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Everything was very good. Boarding and takeoff were on time and organized. Had a good flight

Wheelchair assistance was not complete. The person left me at the departure gate without informing the groundstaff of my requirements. I had to walk to the departure counter to ask for help to reach the plane door. The crew informed me that in future they were not allowed to help passengers like me, senior citizen and Wheelchair passenger with placing their carry on bags in the overhead compartments!

Flight was delayed by over an hour and gate checked bags took 15 minutes to be delivered to the jet bridge.

Seats are way too snug for my hip to knee ratio and the recline on the seat in front of me made my experience worst. My legs had no room at all. Not a plane for people 6 ft or over unless you fly first class.

Delayed for maintenance issue?? Should have been addressed before boarding. Put my bag on an earlier flight, but didn’t ask if I wanted to change to an earlier flight. Arrived to find my bag locked up and no agent to be found when I landed.
