Looked up a biz class reward flight on Continental's website (MUN-ORD op by Lufthansa, ORD-OMA op by United) and also on Aeroplan's site, but had different mile requirements. CO had 100k for 2 passengers and Aeroplan had 120k. Is that normal for being in the same alliance? Was hoping to use 100k Aeroplan miles to book the flight.
