Applied online, and received an "ECoupon Receipt" confirming that I will receive 25K bonus miles after fulfilling the various conditions. However, at no point was there an option to enter my CO frequent flier number. Should I:

(1) Assume that a new CO frequent flier number will be created, and I will then have to merge any duplicate CO frequent flier accounts?

(2) Or try to get a Chase rep to enter my existing CO frequent flier number? Based on past experience, the latter might well take a dozen calls...
