2 player build from scratch

Hi cc Reddit,

My niece and her husband are relatively young, and will have their income increasing pretty comfortably in the next couple of years. They have 1 credit card between them, but both are very responsible so I’m not worried about them abusing credit.

Knowing what you know today, how you would you start their 2 player game from scratch? Any particular path you would take for the first year?

They are looking to travel and have Southwest and American as their closest hubs. Both have scores in mid to high 700s, and they are not opposed to churning or business cards.

Thanks
