I was traveling last week. My outbound on Monday was not affected but my inbound was delayed by an hour due to staffing shortages. The plane that came from Houston to pick us up was late but we were able to board quickly. We actually boarded the plane and taxied to the runway but had to hold for 30 minutes due to updated instructions from Houston ATC.
Since I was heading home on a direct flight, it didn't bother me too much. However, there was a young man on my flight who had a connecting flight that he will likely miss depending on if that connecting flight boarded on time or not. He was last seen racing down the hall after grabbing his gate checked bag (we came from a small airport, small plane).
