start in london or boston
hello,
we're planning a rtw trip in november, we live in london and want to go to boston first before heading south to brazil, would it make more sense to start the oneworld explorer in boston or in london?
what credit card would you recommend to use for the payment of the ticket? i have a barclays platinum visa and bnp mastercard gold or would it make more sense to get an amex platinum?
thanks for your help.
