I flew 4X in '25, none so far this year. With connectors, 12 flights total.
All flights were domestic & reasonable. The flight from DEN > Vegas was scary the first 20+ mins flying west over the Rockies.
I use TSA pre-check, almost no lines.
Delta is my fav, but have gotten good service from United, Alaska Air, & Southwest. American was always late and had a dysfunctional boarding process.
Flying out west is different from east/NE due to weather differences. Less delayed flights.
PM flights in the summer months are more risky due to t-storms & delays.
I always get a window seat, bring noise cancelling headphones, something to watch on my laptop, something to listen to during take-offs, etc. Almost never have checked baggage.
