Everyone in the world
can reserve a flight
on United.com.
They simply can’t pay for that flight.
United.com only accepts
American credit cards.
If you are international
(as most serious travelers are
– some of us are homeless),
you have to book on the United country site
your credit card belongs to.
Yes, I know, madness.
Especially if you have multiple credit cards
with multiple addresses.
The world is global.
Make certain your website is also.
