I'm looking to get a CC with the best reward in terms of airmiles so I can upgrade from PE to Biz on flights to San Fran in 18 months time. I want either a MasterCard or a Amex/MasterCard duo. Will be spending £5K a year on Amex and £10K on MasterCard. Don't mind BA or VA. Obviously a sign up bonus will factor as well.
Would like members thoughts and any tips would be more than welcome.
