Data for this study comes from an opaque destination product offered by a European carrier. The opaque destination
product enables customers to receive known prices (at steep discounts) in exchange for their willingness to accept uncertainty
in their travel destination (but not their travel dates). Customers traveling from a particular airport are told that
for a round trip fare of 39.98 euros, they will be randomly assigned to one of approximately ten destinations. If one or more
of these destinations is unappealing, the customer may elect to exclude them for a fee. For each city excluded there is a fee of
5 euros. A minimum of three destinations must remain in the choice set, as the airline company must maintain some
opaqueness so as to not dilute revenue from their traditional products. All destinations included in a package are served
via non-stop flight.
