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.

Easy on easy off and the staff onboard were wonderful. Left on time, arrived a bit early.

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.

They did everything right and everything happened right on time.

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

The flight was smooth, the crew was great but the plane was quite old

Flight was warm for first few hours and quite rough

Flight was delayed several times. At one point, they "pulled back" 15 minutes from the delayed boarding and sent a text saying we would board sooner than previously advised. The flight then was delayed again. And when we boarded, there was an unspecified technical issue which had us waiting in the plane for about an hour.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

1st flight had mechanical issues after we boarded and almost took off. They tried to fix on runway but couldn’t do we went back to the gate. They couldn’t fix it there either. So we had to deplane and board another plane 2 hrs later. All in all our flight was delayed 4 hrs so we had to cancel some business meeting we had in London for the morning since we were supposed to arrive at 7am and did not arrive until 11:45am. Also, the 2nd plane had mechanical issues as well but fortunately they were able to fix on runway.
