I am new to this forumnand hope to ask a few VERY basic questions. I am interesed in purchasing two first class tickets to Europe next summer: 1) I just received my Capital One Venture Card. May I apply for other cards and combine the points from multiple cards? 2) any suggestions on what other cards to get? How many? 3) does it make sense to join an airline mileage program as well? My credit score is very high. Thanks!
