I keep my Chase Trifecta but if I had to part with either the Ink or CSP it would be the CSP. Follow Million Mile Secrets' step by step guide on applying for a business card if you don't think you have a business ;-) We get most of our UR points through the Ink. We purchase gift cards for Whole Foods, Disney, Macy's etc. at Staples or Office Depot to get 5 miles per dollar. The majority of our Adventures by Disney trips,
Disney Cruise trips, annual passes, DVC dues etc. have all earned 5 miles per dollar by getting Disney gift cards at office supply stores with the Ink card. We tried the Raise/Target/Disney gift card hack and saved about $800 on DVC dues and $1500 on the Adventures by Disney River cruise. However, booking first class flights to Jackson Hole for the Winter in Wyoming ABD trip this year sucked 200,00 UR points from our stash when we transferred them to United for the flights. This mean the Ink card is going to get a workout again LOL
The Ink is under the 5/24 rule too so if you are an authorized user on any credit card accounts those sometimes get counted even though they shouldn't and be aware of that. You may want to remove yourself as an AU or be prepared to explain that on a recon call.
DH and I each picked up a TY Prestige and Premier but I value UR points much higher than I value TY points. If we paid for flights more often or I could get DH to travel in economy (he is now spoiled) then we'd get some decent value from the TY points by earning and burning on paid AA flights. We only picked them up so we could pay for flights on AA to Hawaii next year with the $3200+ in TY points. I simply couldn't stomach blowing over 500,000 AA miles for a first class flight in a domestic carrier. Ok, so maybe I'm spoiled too. If figured we'd be better off paying for it with TY points and earn the butt in seat miles.
