Good advice, one airline and one hotel. However, you should see what the preferred airline and hotel group is for your company. While cash back is nice at 2% of total spend, if you are able to do mainly Hyatt, the 3 points per $ at Hyatt properties, with Hyatt Chase, comes out better, assuming Hyatt valued at 1.6 cents per point. Using hotel points for awards can easily get a 2 to 4 cent per point value, so it depends on what you like. And how you will eventually use the miles and points. Also, keep in mind that Hilton, Marriott and SPG do have more properties, though Hyatt seems to be the better program, IMHO. Each have their own branded CC but only Hyatt and SPG points would be equal to or better than the 2% cash CC you have. Except for the sign up bonuses.

Work on getting status ASAP, as the benefits are worthwhile, better seating on the plane and more perks at the hotel.

And congratulations on landing a job in this economy.
