Correction - (to myself) - same record will carry status of passenger supplying PPs.

In reality, it will be very rare for 4 passengers on one record to clear ahead of time. If UA opens only two upgrade seats, the 4-passenger request will be skipped over for the next single or double passenger requests. You might want to split the record into two (one adult and one spawn) each. I think status is supposed to carry to split records, as long as PPs applied ahead of split.
