All travel should be in the same class of service. When different classes of service are involved in a journey, the required mileage for the higher class will apply.
Premium Economy Class is not eligible with an Economy Class award, but is eligible with a First Class award or Business Class award.
Please note that no mileage will be refunded if downgrading to Economy Class due to change of aircraft.
Example: When the distance of the surface sector is greater than the distance from the first flight sector's departure city to the surface sector's starting point.
Award tickets cannot be upgraded (to the next higher class of service) by paying the fare differential or through combined use with an upgrade award.
There are no restricted travel dates.
At other times the number of seats available for award travel may be limited, or may not be available.
