Question
My parents are trying to choose a credit card for $250K in annual expenditures and can only use Visa or Mastercard.
They do not travel much for business, but will likely travel significantly for vacations starting 2-5 years from now. (i.e., international biz class redemptions would be worthwhile)
I've done some research on FT and am leaning toward Diners Club/Mastercard for the airline flexibility and British Air promotions. They do not have a Fidelity account so the 1.5% rebate card is not an option. Considered the GM 5% rebate card, but they don't plan to buy GM.
Recommendations?
