Flight was delayed and no reasons provided. After the passengers were boarded, the crew made announcement that the captain has jot arrived and he would take another 15 mins. All passengers patiently sat until the captain came and started. Terrible experience!

Flight was delayed and no reasons provided. After the passengers were boarded, the crew made announcement that the captain has jot arrived and he would take another 15 mins. All passengers patiently sat until the captain came and started. Terrible experience!

This was one of the worst flights I’ve been on in years. I upgraded to comfort and had such an uncomfortable experience. The person next to me was oversized - which I understand - however, they took up their space and mine. I could only use about 50% of my seat space to not be physically touching this person the entire flight and there was no spatial awareness. I also could not use the seat outlet because their body was obstructing it. It was very inconvenient. Their body kept touching me repeatedly during the flight and I felt very uncomfortable. To pay more for an upgraded space and then not even being able to use it was highly disappointing.

Only water, tea or coffee served midflight, even to comfort seating. Man next to me needed two seats and took up a portion of my seat and Delta did nothing.

I was given middle seat on this flight and prior Boston to Seoul flight That is a problem for long flights, Kayak system did not give me a change to select my seats and assigned me middle seats regardless of my elevated status in Delta. This needs immediate attention.

It was last minute due to weather - considering - it was amazing! Good smiles, friendly staff and they were making sure we knew what was going on when and where.

Flight taking off must have been behind, because there was no pre-departure drink for first class like normal. Also, person in front of mine’s seat got stuck in the as far back as it normally goes position for the whole flight even during landing, flight attendant unable to fix it. Gate was not empty when we arrived, but that is MSP’s fault since was overdue for push back, not Delta’s, so had to sit on tarmac for a while and international flight so then still had to go through customs. Flight crew was excellent throughout though!

Delta’s staff is unmatched. From the gate agents, to the pilots, to the flight attendants… all top of the industry.

The entertainment screens were not working and there was no air condition the entire flight. Very uncomfortable.

I really liked the legroom. I am 6’4”.a at For some reason our seats were not together and using the app to fix it didn’t work. Passengers were nice enough to move for us but you should absolutely ensure a parent sits with their child.

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.
