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

Flight was warm for first few hours and quite rough

My flight out of Baton Rouge to Atlanta was delayed by a half hour. This got us into Atlanta airport 30 minutes late. I ran through the airport to get to my connecting flight. As I approached the boarding gate, I saw the boarding door was still open and a passenger was being checked in. But when I got to the gate, the boarding agent told me they had already given away my seat and there were no empty seats on that flight. So I had to take a later flight. That has never happened to me before. Very frustrating.

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.

On this flight I felt the food offering was not as complete as on previous flights. The tomato salad was a bit off and there was nothing additional such a bread or butter. The breakfast was only one option, so you either ate what they had or ate nothing. The crew was efficient, but most seemed frustrated throughout the flight. The flight arrived early and was obstacle-free, so I’m overall quite happy, but the shine in the rest of the experience just wasn’t there.

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

The plane was very warm upon entering. This was a bigger problem as the weather was cold so people were dressed accordingly.

Overall, the flight from Atlanta to Orlando was acceptable, albeit delayed and the typical temperature issue on the plane (hot) which has become somewhat expected. However, the staff at gate B22 for connecting flight DL1562 was disappointing. And to clarify, there were two gentlemen behind the counter — one pleasant and the other, Larry. Without question, Larry should not be in hospitality. My wife and I were first in line and when Larry walked in behind the desk, my wife greeted him with “Hiii Larrry”. And while she can be bubbly at times, and I get that it was late, the conversation morphed as Larry asked if she was drunk. At first I assumed he was joking (still not appropriate) but he was not. Clearly he was having a bad day or maybe just hates his job. In all cases, his behavior was unacceptable and offensive. The only saving grace is that he was equally rude and dismissive to all of the surrounding guests as well—although, I’m not sure if that is a good thing or not.

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.
