Airline Baggage Fee Calculator
Estimate airline baggage fees by carrier, bag count, and weight class.
Covers carry-on, first and second checked bags, and overweight bag fee schedules.
Estimated Baggage Fees
Airline baggage fees vary widely by airline, route, ticket class, and frequent flyer status. Calculating total baggage costs before booking can reveal that a “cheap” fare is actually more expensive than a full-service carrier.
The Cost Comparison Formula:
True flight cost = Base fare + (Bags × Bag fee) + Seat selection fee + Other fees
Typical US Domestic Baggage Fee Reference (2024):
| Airline | Carry-On (Economy) | 1st Checked Bag | 2nd Checked Bag |
|---|---|---|---|
| Spirit / Frontier | $35–$65 | $35–$65 | $45–$75 |
| American / Delta / United | Free | $35 | $45 |
| Southwest | Free | Free | Free |
| Alaska | Free | $35 | $45 |
Overweight and Oversize Fees:
- Bags 23–32 kg (51–70 lbs): extra $100
- Bags over 32 kg (70 lbs): extra $200
- Bags over 158 cm (62 linear inches): extra $100–$200
Worked Example:
Family of 4 flying Spirit, each with 1 checked bag:
- Base fares: 4 × $89 = $356
- Bag fees: 4 × $55 = $220
- Seat selection: 4 × $18 = $72
- Total true cost: $648
Compare to United at $129/person (bags included):
- Total: 4 × $129 = $516 — actually cheaper
Practical Tips:
- Weigh bags at home before leaving — airport scales are accurate and fees are immediate
- Wear your heaviest items on travel day to reduce bag weight
- Airlines measure all three dimensions for oversize: length + width + height must be under 158 cm total
- Status holders (Gold, Platinum, etc.) usually get 1–3 free checked bags — check your tier
