Tips to Find the Best Deals

Want to maximize savings? Follow these expert travel tips:

1. Be Flexible with Dates

Shifting your departure or return date by even one day can save you hundreds of dollars. Use AsairSpace’s flexible date search tool to compare fares across a week or even a full month.

2. Fly Early or Late

Red-eye or early morning flights are usually cheaper and less crowded. Plus, you’ll beat the lines at TSA and arrive with more of your day ahead of you.

3. Use Budget Airlines Wisely

While budget airlines offer lower base fares, remember to factor in baggage, seat selection, and other fees. A seemingly cheap ticket can become expensive quickly if you’re not careful.

4. Book Roundtrip or Multi-City Flights

Booking a roundtrip instead of two one-way tickets often reduces the total fare. Consider open-jaw or multi-city options if you plan to visit nearby destinations like Nashville, Charlotte, or Birmingham.

5. Check Secondary Airports

Chicago’s Midway (MDW) and Atlanta’s Hartsfield-Jackson (ATL) are the primary airports, but occasionally, smaller airports near these cities offer regional service at a discount. Use AsairSpace’s airport comparison tool to review your options.
