Nonstop vs. Connecting Flights From Atlanta to San Antonio

Nonstop Flights

A nonstop flight from ATL to SAT is usually:

  • Fastest overall (around 2.5 hours in the air)
  • Most predictable for timing
  • Ideal if you’re:
    • On a tight schedule
    • Traveling with kids or older adults
    • Trying to minimize travel stress

For many Atlanta-based travelers, nonstop flights are available most days, especially mornings and evenings.

Connecting Flights

If nonstop options don’t fit your time or budget, you may see routes with one stop, often connecting through another major hub. With a connection, you may:

  • Add 1–4+ extra hours to your total time
  • Have a layover in cities like Dallas, Houston, or Charlotte
  • Face a bit more uncertainty if there are delays

These can sometimes offer cheaper fares, but if your priority is total travel time, nonstop is usually the better choice.

At Hartsfield-Jackson, lines for security and check-in can be long, especially at:

If you live in or near Atlanta and have some flexibility, scheduling flights outside of peak rush hours can make your airport experience smoother.
