Frontier baggage allowance: a free personal item is not a free carry-on
An overhead carry-on is a different category: up to 24 × 16 × 10 inches and 35 pounds, with purchase or bundle conditions. The base checked-bag reference is 62 total inches and 40 pounds; certain bundles or status benefits differ. Do not import another airline’s 50-pound standard into every Frontier booking. Read the bundle and baggage purchases in your reservation before packing. Measure the under-seat bag and the overhead suitcase separately, then weigh each checked piece. Use Frontier’s bag-price checker for the actual trip and purchase timing instead of assuming a fixed fee. Before paying, verify the passenger, direction, category, and weight entitlement. Keep the receipt with the booking. When a bundle includes a different checked-bag weight, retain that confirmation rather than relying on the base example. An additional-piece purchase does not by itself establish permission for oversize, overweight, or restricted contents.
