I was thinking about this previously and I just mentioned it in another thread but thought I should create something dedicated to this question. I see a lot of people (myself included) who get drawn into this points/miles game and credit card churning etc. Its all fine and dandy but in all seriousness how long can you sustain this? How long before you've exhausted all the sign up bonuses? There are people who state oh they want to be able to travel intl J/F once a year and domestic once/twice a year for little to no money & think that they can sustain this for years to come. I reevaluated my position and I honestly do no think a single person can sustain this off credit cards alone for more than 3yrs. I've been on one Intl trip and about to book my 2nd one, (these are for me & the fiancee) and I think I'm done w/UA & UR for those. If we repeat what I did w/my Fiancee, that might yield another 2 (but honestly who am I joking, both UR point bonuses & VR are going away/down) + the Citi AA might give us another 1 trip. So between two people, we're talking 9 RT or 4.5 RT per person. So unless people actually fly or spend an exorbitant amount on their cards, how do you sustain this?
