The song "Jet Lag" by Gavin Haley tells the story of a man who is struggling to forget about a past love. He confesses that he took a flight early in the morning just to see her, but she was gone by the time he arrived. He reminisces about the time they spent together, feeling high and happy, but acknowledges that what goes up must come down. Despite recognizing that their relationship can't be salvaged, he still finds himself unable to let go and move on. He realizes that she has moved on without him and is now in love with someone else, but that doesn't diminish his strong feelings for her. The chorus repeats the theme of what goes up must come down, adding that what they lost can't be found and emphasizing that he still has it bad for her, despite her absence in his life. The bridge of the song takes on a more confrontational tone, with the narrator acknowledging that his past love has cut him out of her life and questioning whether she has heard the song he wrote about her. Overall, "Jet Lag" is a melancholy reflection on the pain and nostalgia that can come from a failed relationship.
