Airports and airlines will be celebrating Valentine’s Day this year.

But Oakland San Francisco Bay Airport (OAK) and Southwest Airlines are getting a head start by bringing back a free Valentine Day’s mailing service for the second year in a row.

Through Wednesday, February 11, passengers traveling through OAK can pick up free OAK-themed postcards to write love letters to their sweethearts.

Then they can drop those cards in Valentine-themed drop boxes located at Gate 3, Gate 14, Gate 20 and Gate 27/28.

All valentines collected by the end of the day on February 11 will be mailed, at no cost to passengers, in time to arrive by Valentine’s Day (Saturday, February 14).

Sweet!
