Love in the Air is the WoW version of Valentine's Day.

Most of the holiday activities are completed around your faction's capital city.  The currency of this holiday are Love Tokens which can be used to purchase various items needed to work on the Valentines meta achievement towards What a Long, Strange Trip It's Been, as well as miscellaneous fun and vanity items and the Swift Lovebird mount.  Completing all the achievements needed for the holiday's meta, Fool For Love, will reward the title [name] "the Love Fool."

In addition to doing dailies and killing the holiday boss, you can earn Love Tokens by farming Lovely Charms from mobs out in the world. You can turn every ten Lovely Charms into a Lovely Charm Bracelet which trades in for Love Tokens at a 1:1 conversion rate.

The holiday boss is a trio of three undead mobs collectively called the Crown Chemical Co. Apothecaries.  They are located in the courtyard of Shadowfang Keep and are only accessible through the Looking for Dungeon tool.  Once a day defeating the boss will reward a Heart-Shaped Box which can contain several fun items including an ultra rare Big Love Rocket mount and Toxic Wasteling pet and additional Love Tokens.  While subsequent kills that day will not drop reward a Heart-Shaped Box, the boss also drops necklaces every kill.  There is no limit to number of tries a day, meaning you can kill them continuously until you get your desired neck piece.  Beating this encounter also rewards the achievement Tough Love.
