Hi, new here. Sorry if this has been asked before. Tried to search, but no luck.

I'm brand new to travel hacking. I just got the Barclay Arrival Plus card and am now weighing the benefits of adding the chase sapphire preferred card to the mix, once I reach my 3k spend.

I am thinking my strategy would be to use Chase strictly for purchasing flights and Barclay for travel expenses, since I can redeem my points for many more things, such as AirBnB stays and train tickets. After reaching my Barclay spend, I'll primarily use the Chase card. I'm thinking this strategy would save me the most money as a beginner who really doesn't understand credit cards and travel hacking very much.

Planning my first trip for Europe next year.
Any suggestions are welcome. I Thanks!
