Got my United Explorer card by Chase in the mail yesterday. The package did not included any info about any bonus miles i.e. 30K or 50K or any other ‘K’. How should i proceed to figure out whether i will get any bonus miles or not. I checked my online account but it does not have any info over there also. Further, my online account also does not indicate anything about my existing milage plus miles. However, my card does have my milage plus account number on it. Help please !!
