how much is an air mail letter to Sweden
From where?
90 cents
It depends on the currency you're using.

1.45
$2.10 if you buy a prepaid airmail letter from the postoffice... not sure how much an international stamp is if that's what you're asking. A postcard is $1.80, so i'd imagine $2.50-$3
1.15
1919.
Red and white striped.

Airmail takes a few days, surface mail may take over a month. Your choice.
