Though the American Airlines Boeing 757 is fitted with individual telephones at each seat position, they are not of the variety where you can simply pick up the handset and ask for an operator. On many aircraft you can talk from one seat to another in the aircraft free of charge, but if you wish to access the outside world you must first swipe your credit card through the telephone. By Ted Olson's own admission, Barbara did not have a credit card with her.
It gets worse. On American Airlines there is a telephone "setup" charge of US$2.50 which can only be paid by credit card, then a US$2.50 (sometimes US$5.00) charge per minute of speech thereafter. The setup charge is the crucial element. Without paying it in advance by swiping your credit card you cannot access the external telephone network. Under these circumstances the passengers' seat phone on a Boeing 757 is a much use as a plastic toy.
Perhaps Ted Olson made a mistake and Barbara managed to borrow a credit card from a fellow passenger? Not a chance. If Barbara had done so, once swiped through the phone, the credit card would have enabled her to call whoever she wanted to for as long as she liked, negating any requirement to call collect.
