Personal item, carry-on, checked bag, and overweight fees on Spirit Airlines, plus how to avoid the gate price.
The Spirit baggage model
Spirit Airlines is the original US ultra-low-cost carrier and the inventor of the modern unbundled fare. The base ticket (Bare Fare) includes a single personal item that fits under the seat, nothing else. Cabin bag, checked bag, seat selection, water, and printed boarding pass are all priced separately. The cheapest path is to commit to the bag count at booking and never change it.
Personal item rules
Spirit's free personal item is 18 × 14 × 8 inches (45 × 35 × 20 cm). This includes wheels and handles. The bag must fit completely under the seat in front of you. Spirit gate agents do enforce the sizer at major bases (Fort Lauderdale, Las Vegas, Detroit, Atlantic City). A standard 18-inch underseat 'spinner' is borderline; a soft backpack is a safer bet.
Carry-on (overhead bin)
An overhead-bin carry-on is 22 × 18 × 10 inches and costs:
- USD 39–69 if purchased at booking
- USD 49–79 if added during online check-in
- USD 65–79 at the airport desk
- USD 99 at the boarding gate
The booking-versus-gate gap is the largest in the US industry. Buy at booking even if you are not 100% sure you will bring a carry-on, the cost of a wasted USD 39 is much less than the cost of a forced USD 99 at the gate.
Checked bag pricing
Standard checked bags up to 40 lb / 18 kg cost USD 30–65 online for the first bag, USD 40–80 for the second. Overweight fees are punitive: USD 50 per bag for 41–50 lb, USD 100 for 51–70 lb, USD 150 for 71–100 lb. Bags over 100 lb are not accepted. Oversize is USD 150 for any bag exceeding 62 linear inches (length + width + height).
Bring a luggage scale. The Spirit overweight fee is the same on a 41 lb bag as on a 49 lb bag; rebalance to two bags under 40 lb if you are over.
Save with the Saver$ Club
The Spirit Saver$ Club (USD 79.95/year) discounts bags by USD 5–25 per bag per direction and unlocks lower base fares. It pays for itself in roughly 2–3 round-trips with bags. For occasional flyers it is not worth it; for once-a-month flyers it is a clear win.
Common Spirit-specific gotchas
- Boarding-pass printing at the airport costs USD 25 unless you are a Free Spirit member. Always check in online.
- Spirit sells the Big Front Seat (extra-legroom seat in row 1–2) often for USD 35–80; on a 4-hour flight this is genuinely worth it.
- Spirit's elite-status equivalent is built into the Saver$ Club; there is no traditional miles-based status.
- Spirit is now part of the Pegasus group post-Chapter 11; expect continued network changes through 2026.
