Attempting to book CLT-MUC, ZRH-CLT. I can get the itinerary review page to price out correctly at 60k per ticket for two tickets in coach. I get to the traveler info screen enter travel companions info. I click next and it puts the itinerary on hold saying I don't have enough mileage. I look at the saved itinerary and it has bumped to to business/first class. I have more than enough miles for the coach ticket. I can recreate this numerous times and have had to cancel holds. Any ideas?
