It was strange that the flight attendant was so adamant about having phones turned to airplane mode that he was calling out names from networks shown and waiting until they were all gone. I've never experienced that before, and after already working through an hour+ delay, it felt tone deaf. I take dozens of flights per year and have never experienced anything similar.

It was strange that the flight attendant was so adamant about having phones turned to airplane mode that he was calling out names from networks shown and waiting until they were all gone. I've never experienced that before, and after already working through an hour+ delay, it felt tone deaf. I take dozens of flights per year and have never experienced anything similar.

Poor communication, we sat on the plane for an hour before pushing back. They were oversold and with a full plane kept looking for someone to step off for someone else to board. So after an hour wait at the gate we missed our departure window and proceeded to spend an additional hour on the tarmac waiting for a refiled flight plan according to the pilots. Occasional updates, somewhat insensitive crew to passengers needing to use the lavatory (it was 2 hrs beyond what anyone expected). Overall just poor execution...especially when the flight was listed as "arriving early" up until about 30 minutes past our departure time.

The Columbus-based WestJet crews that cover Delta commuter flights between LGA and CMH are excellent - this team included. Our flight today landed 40 minutes early, which is unheard of when flying out of LaGuardia. I've flown with the same crew in more challenging conditions, and they always rise to the occasion with helpful communication to the passengers so that we may manage expectations.

We were skipped when the snack cart passed and then the attendant said we weren’t . I am disabled and was in a row toward the back of the plane which was very difficult for me to navigate. Disabled people should not be forced to walk the plank.

Flight delayed due to ground hold. Republic airways did a great job.

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.

A 12 hour flight during the day with one real meal service - are you kidding? Also the breakfast was one of the worst and not what was listed

The flight attendant on Korean airline was a super nice. it’s one of the best over-sea airline I flew so far.

All in all it was a long flight in economy class. There’s only so much comfort one can expect on a plane. The seats felt exceptionally hard and as an over 6’ individual I’ll seldom feel great about legroom. The food was good and the flight crew was great. The headphones provided for the movies were terrible, though

Crew handling the boarding at the gates are quite aggressive with the passengers and must be given training/ refreshing courses to improve customer experience.
