Did Lost make references to Love Actually? I noticed some similarities:
Toward the end, many of the main characters happened to meet up at a concert that until that moment the audience didn't know was the same concert everyone was talking about.
At that concert, the song "Catch a Falling Star and Put it in Your Pocket" was sung as the main song. This was also featured significantly in Lost (sung by Claire and Kate, and even becoming part of the score).
The guy who was in love with Keira Knightley gave her a message in a very similar fashion to that used by Juliet in Lost--holding up boards with the message on them and dropping them to reveal the next one. And, hang on, Keira Knightley's name was Juliet.
A fading rockstar (Bill Knighy or, on Lost, Charlie) makes a comeback and realizes he has finally found true love.
Some of the major tie-together scenes revolve around airports.
Do you think Lost intentionally referenced Love, Actually?
