The short verdict
Cabin space: Spirit Airlines allows the larger cabin bag by volume (56 × 46 × 25 cm) against Frontier Airlines (61 × 41 × 25 cm).
Both airlines count baggage differently across fares, so compare the checked tables before you book the cheaper ticket: a fare with no bag included can end up costing more.
