Showing 9 unoccupied seats (not necessarily unsold), mySQUpgrade at USD 3000 or 86500 miles from PE (P class). Upgrade with miles option indicated not available but mileage redemption was available via mySQUpgrade so grabbed it from there. Instant transfer from Amex.
I see mileage accrual is based on original class booked, but is it normal to see the fare class change to D from the original P when using mySQUpgrade?
Yeah it's normal, so you will see D on your booking, but in the Miles Statement it will show P.
