Can the cost for a trip be split between indexes?
NO, the travel cannot be split between indexes on one reservation. To accomplish this, you may book one portion of the trip on one index and book a separate trip on the next index. For example; the outbound portion and hotel is on one index and the return trip is on a second index. You will book a one way outbound ticket and the hotel and indicate which index code to use. You will send that to be approved and then ticketed. You will book a second one way return ticket and indicate the correct index and have that approved.
