Just booked for 2 people:
LAX-SLC-LHR on Delta: 62.5k miles + $5.60pp: (R) and (O)
AMS-IAH-LAX on United: Plan B, paid 70k + $53.96pp: XN waitlisted for I (i.e. Plan B)
Someone elsewhere suggested I should have been charged less for the United flight, that a Business Saver Award is only 57.5k even though the cabin is all BusinessFirst?
