(4) You must assist prospective passengers who indicate that they are unable to use your Web site due to a disability and contact you through other channels (e.g., by telephone or at the ticket counter) as follows:

(i) Disclose Web-based discount fares to the passenger if his or her itinerary qualifies for the discounted fare.

(ii) Provide Web-based amenities to the passenger, such as waiving any fee applicable to making a reservation or purchasing a ticket using a method other than your Web site (e.g., by telephone), unless the fee applies to other customers purchasing the same fare online.
