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

Seat was too small for someone as tall as I am. I was behind an exit row making my leg room even less. There flights were delayed by multiple hours. Some weather related and others staff related. The plane was hot. Horrible experience.

The Atlanta airport had thunderstorms, which caused our flight to be delayed by multiple hours. Once we were able to board.the gate agent was rude and was trying to rush us onto the plane because the team in the plane was about to run out of hours once we were all aboard the plane they ran into an issue where the catering truck was filling up the back of the plane and they left and had to come back because they didn’t fill it up all the way, causing even more of a delay. My seat was very tight. I didn’t have a lot of legroom overall this was a miserable experience.

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 staff and the boarding procedure were all amazing . The one flight was not equipped with WIFI which now adays seems odd. All in all the experience was good

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.
