Don't understand why I have precheck leaving St Louis but never have it returning from Washington (Reagan)

Aug 2, 2019

Short and sweet. As all air travel should be!

Given that I had a Basic Economy ticket I would say my experience met my expectations. The seat assignment hassle is my only major complaint.

May 14, 2019

Security check at STL over the top annoying. Both times I went through it led to full pat down and body search with skin tests and full carry on luggage search. No reason was ever given why.

Small plane tight. No room for carry on bags but it worked out. Departure was 1 hour later due to a mechanical issue.

Flight itself was pretty bumpy right before landing and as we landed. But overall I had a good experience

Smoothest ride ever! Stewardess was professional to me, but I saw her acting unprofessional to others.

Aug 19, 2018

Nicest stewardess I’ve ever had!!!!

The baggage claim carousel stopped right after it started; took about 15 minutes before it started again.
