Review of Delta Air Lines flight from Houston to Atlanta in Economy

Greeting Flyers!
It's been a while since I last flown Delta Airlines and with my traveling arrangements directed me to use Delta, I decided to make this trip report. However, this will not be all of them, as I will different airlines throughout my summer break.
Itinerary was as follows for this trip segment;
MAY 22-23, 2018
DL 1912 HOU-ATL
DL 0108 ATL-MAD
July 5
DL 0109 MAD-ATL
DL 2365 ATL-HOU

Arrival and Houston Hobby Airport

On the day of departure, I had my uncle drop me off at Houston Hobby Airport around two hours before boarding. I made my way towards the luggage drop (as I had my e-boarding pass) and dropped off my suitcase. And made my way towards security. Surprisingly, it wasn't as congested as I expected to be, so I was in and out in about five minutes or so.

Check-in area for AA, B6, and DL
One of the unique things present in Houston Hobby is their live concert that they do from time to time at the central area by the food court, which includes Wendy's, Pappasito's, Barry's Pizza and Hunan Garden.

Performers entertaining the travelers that goes by, myself included.
Like with check-in, non-Southwest airliners are consolidated to left side of the terminal from gates 28 to 32. I decided to find a plug spot and recharged my phone, looking outside the windows periodically to see what was going around the apron and runway area. Pretty much only activities were Southwest flights arriving and departing Hobby airport. But off to the side, I saw a American Eagle CRJ-700 and strangely enough a Delta 757 (because Delta operations to Atlanta from Hobby are usually the 717).

Nope, no sight of my aircraft yet….
Then about 40 or so minutes before take off, I finally spotted my aircraft coming to our gate 32,

My flight has arrived! Featuring a Southwest 737 in the foreground.

Boarding started at 1230, about 10 minutes behind the proposed boarding time, but the boarding process was smooth.

My gate area, an American Eagle flight to Dallas was boarding during this time.

On Board

Once I got on board, the FA's greeted me and I made my way towards 20D, an emergency exit row. As I sat down, a couple asked me if I can move a row back so that they can sit together, me being a moderately generous person said yes, so I was now in 21C, which wasn't a big deal for me.

The door closed at 1252, about 8 or so minutes before our scheduled departure. The FA went on to inform us about or flight which would take us to Atlanta in 1 hour and 42 minutes. We pushed back about three minutes before our scheduled time (which is always welcoming despite only being three minutes) and before we know it, we were on our way to Atlanta.
Once we got to above 10,000 ft, the cabin crew sprung into action making their way from the front to the back. Once they got to my row, I asked for Ginger Ale with the snack mix they were handing out (I know, should've gone for their biscoff but I was not in the mood for it).

Once that was done, rest of the flight was very uneventful as I just spent my time listening to music and playing sudoku. We landed into Atlanta 15 minutes ahead of schedule but making our way to our gate made our arrival right on time.
We will pick up when I write the next report.
