Passenger Type Used in Pricing Passenger Type used in Pricing is the passenger type used to get the lowest available fare for your selected flights. This may be different from the passenger type you entered because AA.com always searches for the lowest available fare regardless of passenger type. For example, if you specified 'child', you may see 'adult' in this column because that was the lowest available fare for your selected flights. If you choose to pay using a credit card or U.K.-billed PayPal account, a processing fee of £4.50 per ticket may apply.
