Now here's the fine print: The same itinerary means that each and every element of each offer matches; airline(s), flight number(s), itinerary, date(s), number of customers and seat type. 'Offered and available for booking' means that the itinerary you found is actually live on a Major OTA Competitor's site and available to be booked by the general public at the time you contact us, as determined by our customer service representatives. For purposes of the PMP, a 'Major OTA Competitor' means the U.S. English-language websites of Expedia.com, Orbitz.com, Priceline.com and Travelocity.com. The PMP does not apply to fares offered on membership program websites, corporate discounts or rates; group, charter, rewards program, incentive, meeting, convention, or consolidator fares; or fares available only by using a coupon or other promotion not offered to the general public. Military, student, government, tour operator, bulk, vacation package or 'Web Only' fares are excluded. The PMP does not apply to "opaque" tickets (where the airline booking details are unknown until after purchase) or tickets issued under a 'bidding' or 'auction' model. Fare errors are also excluded.
