Going from NYC-FRA next week in bus. class and trying to decide between CO and SQ. Know that SQ has far superior service but the mileage differential seems pretty great. I'm Gold on CO (and actually close to Platinum) so CO would offer 250% miles (100% gold bonus and 50% class of service). Understand that SQ would only give 25% class of service and doesn't even give any bonus to UA elite. Is that correct? Any other mileage considerations that might tip the scales? Thanks.
