How long is the flight from ATL to HTX?

Excuse me, I was wondering if you could possibly provide me with some information regarding the duration of the flight from Atlanta, Georgia's Hartsfield-Jackson International Airport (ATL) to Houston, Texas's Hobby Airport (HTX). I'm planning a trip and I'm trying to figure out how much time I should allot for the journey. I'd really appreciate it if you could give me an estimated flight time, or if there are any factors that might affect the duration, such as weather conditions or the specific airline I'm flying with. Thank you in advance for your assistance.
