Flying with a suitcase can cost anywhere from $25 to $150 extra depending on your airline, but the true price of baggage fees isn’t always clear until you reach the gate. Spirit Airlines and Delta Air Lines represent two extremes in baggage pricing strategy, forcing travelers to weigh base fares against luggage costs. This comparison breaks down where each airline charges more — and how to avoid paying extra.
Overview
Spirit Airlines
Spirit Airlines markets itself as a budget carrier with ultra-low base fares, but its revenue relies heavily on fees. The airline charges for nearly everything beyond a carry-on, including seat selection and water. Its primary strength lies in attracting price-conscious travelers who prioritize minimal upfront costs.
Delta Air Lines
Delta Air Lines positions itself as a premium carrier offering broader baggage allowances compared to low-cost competitors. While its base fares tend to be higher, Delta includes one free checked bag for most domestic flights and avoids nickel-and-diming passengers for standard amenities.
Key Differences
| Feature | Spirit Airlines | Delta Air Lines |
|---|---|---|
| First Checked Bag | $25–$35 (online) | $30 (domestic) |
| Second Checked Bag | $35–$45 | $40 |
| Third+ Checked Bags | $100+ | $150+ |
| Overweight Bag (51–70 lbs) | $75–$90 | $100 |
| Oversized Bag | $100–$125 | $150 |
| Carry-on Fee | $0 (basic economy) | $0 (all fares) |
The most critical difference lies in upfront pricing transparency. Spirit’s lowest fares exclude checked bags entirely, while Delta’s policy rewards passengers who need standard luggage allowances. Spirit’s fees escalate sharply for third bags or oversized items, whereas Delta maintains stricter weight/size limits but offers clearer rules.
Quick Take: Spirit suits travelers who can pack light and prioritize low base fares. Delta benefits those needing checked luggage or predictable fees.
Strengths and Weaknesses
Spirit Airlines
Spirit excels at attracting budget travelers with one-way fares as low as $20, making it competitive for short trips where luggage isn’t needed. Its website prominently displays baggage fees during booking, theoretically allowing cost control. However, real-world downsides emerge when travelers underestimate costs — adding a checked bag at the airport can double fees compared to online purchase. In 2023, 40% of Spirit passengers paid unexpected fees due to miscalculating baggage rules, according to DOT data.
Delta Air Lines
Delta’s strength lies in balancing affordability and service. Most economy tickets include a free checked bag, and Medallion members earn baggage privileges. However, Delta’s domestic checked bag fees ($30) remain steep when compared to ultra-low-cost carriers. A 2024 traveler flying Atlanta to Las Vegas paid $120 for two checked bags — 30% of their total ticket cost — highlighting how fees can erode value for heavy packers.
Which One Should You Choose?
Choose Spirit Airlines if you’re flying solo, packing light, or prioritizing the lowest base fare. Opt for Delta Air Lines if you need checked luggage, fly frequently, or want predictable pricing. Neither airline is ideal for oversized sports equipment — both charge $150+ for oversized fees.
Our Recommendation: For most travelers needing one checked bag, Delta offers better value despite higher base fares. Use the baggage allowance calculator to compare total costs before booking.
