Read the T & C: For benefit to apply, at the time of booking, Citi® / AAdvantage® account must have been open at least 7 days and reservation must include the primary cardmember's American Airlines AAdvantage® number. This benefit is valid for travel booked and ticketed on or after April 2, 2012. If your credit card account is closed for any reason, this benefit will be cancelled. Eligible Citi® / AAdvantage® cardmembers may check one bag free of charge when traveling on American Airlines, American Eagle or the AmericanConnection® carrier to select domestic destinations. Up to four customers traveling with the eligible primary credit cardmember will also get their first checked bag free of charge if they are listed in the same reservation. Waiver does not apply to overweight or oversized bags. This benefit cannot be combined with any existing AAdvantage® elite program benefits, including any waiver of baggage charges. Please see AA.com for baggage weight and size restrictions. Additional terms, conditions and restrictions may apply. Applicable terms and conditions are subject to change without notice.
