Southwest baggage guidelines: do not assume two checked bags are included
Extra size or weight is a separate issue from the number of pieces. The allowance and price have to be checked against the actual booking. Identify the fare, ticket date, traveler benefits, and number of bags before comparing trip costs. Measure and weigh each packed bag, then review the current purchase options. Do not count an ordinary checked suitcase as an assistive device or assume a benefit attached to one traveler covers everyone on the reservation. Before paying, verify the direction of travel, passenger, bag count, and any excess charges. Save the receipt with the booking. When a bag contains medical equipment or an unusual item, request the relevant handling rule rather than applying a general suitcase fee. This answer does not quote a fixed fee where the required booking details have not been supplied.
