I everyone, I'm new to this miles/points world and I have a question about airline credit cards. Am I able to combine miles earned on airline credit cards from two accounts? For example, if my wife and I both sign up for the United Explorer Card and get the sign up bonus, can I then transfer both bonuses into my United FF account in order to book award travel? Or would she have to get a United FF account in order to book award travel also? I would like to be able to get the miles into one account so that I can book flights for us together rather than have to book flights individually. Thanks for your help!
