split mileage between two programs on same itinerary
i am flying ORD-ANC-JNU-SEA-ORD over the next two weeks. the ORD-ANC and ANC-JNU segments were upgraded using guest upgrades and the JNU-SEA and SEA-ORD segments were mvp gold comp upgrade (Q class fare).
i called both reservations and mileage plan, but nobody knew a definitive answer. i would like the first two segments credited to my NW account and and the last two segments to AS (i am under the impression the last two segments must be credited to AS since it was a comp upgrade)
anyway to accomplish the above scenario?
