So it looks like FT will be handling its own overseas subscriptions, including the U.S. - the link for U.S. subscriptions on their website now allows all international destinations. The downside is you can only subscribe for a year if you choose U.S., and payment is only in pounds sterling. I don't know if any of my credit cards doesn't charge a steep premium for foreign currency. The link for renewals, rather than new subs with a start date, isn't working properly, so I guess I can wait a while.
