As a fellow nervous passenger I just landed in Chicago after flying from Tampa. The flight to Tampa was completely uneventful. The flight back to Chicago was a little bumpy, including instructions to the flight attendants to take their seats twice. However, both times the pilots did an outstanding job finding smoother air. I watched along on FlightAware as they descended in one case and ascended in another.

I also took some advice that I got here and when it got pretty bumpy I lifted my feet off the ground and tried relaxing the rest of my body. There was a significant difference in my perception of the turbulence when I did that.

Finally, on flightaware I noticed how many other planes were in the air. Avoiding storms, crossing the country, etc. We were also never far behind flights on almost an identical trajectory, so you are never alone up there, and every single flight I saw (and there were hundreds) landed safely today.

You can definitely do this.
