B. Delta’s Liability in the Event of Schedule Changes, Delays and Flight Cancellations
In the event of flight cancellation, diversion, delays of greater than 90 minutes, or delays that
will cause a passenger to miss connections, Delta will (at passenger’s request) cancel the
remaining ticket and refund the unused portion of the ticket and unused ancillary fees in the
original form of payment in accordance with Rule 260 of these conditions of carriage. If the
passenger does not request a refund and cancellation of the ticket, Delta will transport the
passenger to the destination on Delta’s next flight on which seats are available in the class
of service originally purchased. At Delta’s sole discretion and if acceptable to the passenger,
Delta may arrange for the passenger to travel on another carrier or via ground
transportation. If acceptable to the passenger, Delta will provide transportation in a lower
class of service, in which case the passenger may be entitled to a partial refund. If space on
the next available flight is available only in a higher class of service than purchased, Delta
will transport the passenger on the flight, although Delta reserves the right to upgrade other
passengers on the flight according to its upgrade priority policy to make space in the class
of
service originally purchased.
