My flight was not delayed, but my family had a flight earlier in the week that was, by 5 hours. My daughter says she'll never book a late afternoon flight as they seem most likely to be delayed. I personally like the timing and usually they cost less. Also, get on the plan with fully charged devices or a non-electronic form on entertainment.

Allow time for TSA (I had) or figure out the priority boarding (I didn't but will look into it for future flights), I thought they were pretty inefficient. A guy behind me was freaking out because he was going to miss his flight and a bunch of us let him cut the line in hopes he could make it.
