<prompt> Human: I will be on travel for my work for about 6 months which will incur huge costs such as 88day hotel, gas, food, plane tickets, etc. I will be reimbursed for all of these expenses and could use a company card, but have the option of using a personal card and getting the rewards. I dont really know much about the world of rewards cards and could use some advice. My Credit Karma score is 710 if that makes any difference.  <response>: Chase sapphire preferred. Best card everGreat perks and excellent customer service.
