After the initial 5K EQM for the sign-up, there's no real advantage for a 2nd card unless you plan on spending $35K on the second card to get 5K extra EQM. Chase will not waive the annual fee for the 2nd card so you will have to pay the $140. Up until last year, I was able to get Chase to waive the annual fees for 2 personal cards ($60 only on the second one because of the sign-up date) and one business card but not this year. As others have said, there are much easier ways of getting EQMs in this age of DEQM and TEQM.
