Visiting the Frontier Airlines Chicago Office helps travelers master the airline’s specific baggage allowances, policies, and guidelines before heading to O'Hare. Frontier permits one personal item (up to 18148 inches) free of charge with all fares. Larger carry-on bags and checked luggage require separate fees, which are lowest when pre-purchased online. Standard checked bags must weigh under 40 lbs to avoid overweight penalties. To avoid unexpected expenses at airport boarding gates, contact the Chicago support team beforehand to confirm your luggage dimensions and reserve extra bag allowances at discounted rates.
