Allegiant baggage fees

On Allegiant, a personal item is free on the base fare. A full-size carry-on and checked bags are paid add-ons (ULCC model). Carry-on fees are cited $10–$75 by route and when added; the airport fee is often $75 each way. Checked bags are route-specific, per segment — usually cheapest at booking, higher pre-departure, airport often $75 for unpaid bags. Standard checked limit: ≤50 lb (22 kg) and ≤80 linear inches (203 cm). Use Allegiant’s Baggage Fees Calculator / Optional Services on allegiantair.com; do not rely on an invented static nationwide 1st/2nd checked dollar table. Published overweight and oversize add-ons (below) are the main fixed fee numbers on this page.

What’s free vs route-dynamic vs published add-ons

Published overweight & oversize fees

Separate route-dynamic bag prices (carry-on / 1st / 2nd checked) from these published add-ons. Oversize + overweight can stack with the base bag fee — confirm stacking language live. Bag fees are generally non-refundable unless the bag is lost or the itinerary qualifies for a penalty-free cancel (terms).

• Always free: one personal item within 8 × 14 × 18 in under the seat; car seats/strollers; mobility aids / assistive devices; medical equipment (e.g. POC, diabetic supplies); food for in-flight; coat/jacket; diaper bag; umbrella — confirm the full list on the live baggage FAQ.
• Not free by default: full-size carry-on, checked bags, overweight, oversize.
• Base fare = ULCC personal-item-only for cabin bags; carry-on and checked are always add-ons.
• No Frontier-style named bag bundles found — don’t invent product names. Optional seats, priority, or bag add-ons may appear in booking — confirm live labels only.

For size detail on the free under-seat bag and the paid overhead bag, use personal item and carry-on size.

1. Airport bag fee is often $75. Buy at booking — waiting until the counter usually costs more.
2. Fees are per segment (one takeoff + one landing). Round-trips and connections multiply.
3. Oversize + overweight can stack with the base bag fee — confirm stacking language on Allegiant’s official pages before budgeting a combined total.
4. OW upper bound 99 vs 100 lb and max pieces 4 vs 5 — confirm on the live site; CoC generally rejects bags over 99 lb except sports / instruments / mobility.
5. Stale “41–70 lb” OW start — discard unless live confirm; published primary tiers start at 51–70.
6. Carry-on is often paid — don’t bury that under checked-only framing.
7. No invented static nationwide $ for standard 1st/2nd checked bags — route pricing only.

• Add bags online at booking (lowest tier of route/timing pricing).
• Stay ≤50 lb and ≤80 linear inches to avoid published OW/OS add-ons.
• Pack to personal-item only (8 × 14 × 18) when possible.
• Avoid airport counter purchase when unpaid bags are due — indexed airport fee often $75.
• Use the live Baggage Fees Calculator / booking path for your itinerary — never rely on a blog’s invented 1st/2nd checked table.
