Unaccompanied Minor calculateur de frais

An 8-year-old flying Delta round-trip costs $300 in unaccompanied-minor fees: $150 × 2 × 1 (each-way fee × directions × one child) — and the service is mandatory for ages 5-14 on Delta, no opt-out. The cheapest compliant carrier is Alaska at $100 round-trip ($50 each way nonstop — $150 with a connection for ages 8-17 — optional under 13), then Southwest at $200 (mandatory 5-11). But the real constraint is routing, not money: nearly every airline refuses connections for minors outright, so if your route needs one, only Delta (up to 4 flights) and Alaska (ages 8-17) accept it — $300 on Delta. With every booking: one adult gets a free gate pass, and the pickup adult shows a photo ID matching the name on the reservation.

Verdict

Alaska ($50 nonstop) and Southwest ($100) are the cheapest UM fees — but routing, not the fee, is the real constraint: Delta and Alaska allow connections (Alaska's, for ages 8-17); United/Southwest/Spirit/Frontier are nonstop-only.
