When to Book: Cheapest Months & Booking Windows

Always check baggage fees before booking; Southwest’s $35 carry-on fee on DFW-AUS routes adds $140 for a family of four.

Watch Out For: Airline Fee Traps

Southwest’s $35 fee for a second carry-on bag on DFW-AUS routes is a common pitfall—my 2023 trip cost $120 extra due to this. Delta’s $50 fee for checked bags on ATL-AUS flights is another hidden cost. Always verify baggage policies on the airline’s website before booking; Southwest’s "free carry-on" policy excludes larger bags on flights over 500 miles. In 2023, 37% of travelers overpaid due to unconfirmed baggage fees, per Airline Ratings data.
