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.

Weather in Atlanta necessitated an hour's hold on the tarmac before we could leave Detroit. The plane was packed, and I expected some surliness. But no! The crew was fantastic (jovial even!), responsive to people's needs, and kept us informed. Consequently, the passengers took the delay in stride, and what could have been an ugly situation turned out to be no more than a minor inconvenience. The crew were the stars here.

Laura, Jul 2026

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.

My flight was delayed and I got back around 3.5 hours later than expected. I had to get a new connecting flight
