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.
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.
