Read up on how to get cheap fares from Atlanta.
- Spirit Airlines: Known for ultra-low base fares, often starting as low as $20-$40 one-way to destinations like Fort Lauderdale, Miami, or Philadelphia. However, additional fees for baggage, seat selection, and other services can increase the total cost, so review their policies carefully.
- Frontier Airlines: Similarly budget-friendly, with one-way tickets frequently in the $27-$48 range to cities like Denver, Orlando, or New York. Like Spirit, Frontier operates a low-cost model with optional add-ons.
For example, recent data shows Spirit offering flights to Fort Lauderdale for as low as $39 round-trip and Frontier to Denver starting around $48 round-trip, though these prices are for specific dates in May 2025 and subject to change.
Tips to Find the Cheapest Flights:
- Check fare comparison sites like Kayak, Skyscanner, or Expedia for real-time deals.
- Be flexible with travel dates—midweek flights (Tuesday/Wednesday) are often cheaper.
- Book at least 53 days in advance for the best rates, as prices rise closer to departure.
- Consider nearby destinations or smaller airports for potential savings.
Since prices fluctuate hourly, I recommend checking directly on Spirit’s or Frontier’s websites or a platform like Kayak for the latest deals from ATL.
