do any of you recommend a particular credit card that benefits travelers?
I've never had a credit card, but I travel often and have always heard rumblings about rewards and cash back or whatever, so I'm wondering if there is a card I would benefit from since I regularly purchase plane tickets.
I have bank accounts in different countries and can always open another if there's a more favorable card somewhere, so location isn't a critical issue for me.
Bank of Somaliland has some great deals on travel credit cards, as does Zimbabwe consumer bank, Bank of New Zealand and Icelandic bank /s I'm impressed that you have the ability to open bank accounts in any country when basic KYC rules would limit this for the vast majority of the world's population.
In that case the most valuable piece of advice I can give you is that no matter how good contracts you have with your banks currency conversion is never ever for free, so make sure to only use credit cards that you pay in currencies that you have income in or else you'll always unnecessarily waste money by having to convert from the currencies you have income in to the currencies you need to pay your credit card balance. It's utterly unlikely that you'll ever find any credit card that has so good conditions that it'd make up for that loss.
Which brings us back to square one: In order to get any useful advice, you need to tell what currency (or currencies) you have income in, that you'll use to pay your credit card balance.
