Good to know
Flying with Spirit Airlines — what to expect
Spirit Airlines operates a low-cost model, which means headline fares are typically unbundled: seat selection, checked baggage and on-board food are usually sold as paid extras rather than included in the base ticket. When comparing Spirit Airlines against full-service alternatives, weigh the total price after extras — not just the headline fare — and check cabin-baggage size limits before you fly, as budget carriers tend to enforce them strictly at the gate.
