"Flight Path" by E^ST is a song that explores the themes of loss, distance, and the struggle to move on after a breakup. The lyrics depict a relationship that was once vibrant and filled with shared experiences, but ultimately comes to an end. The song begins with the protagonist reminiscing about the time they were introduced to their partner's mother and how well they knew each other's preferences and interests. They describe how everything around them felt like music when they were together. The chorus reflects on the good times they spent together, both during the day by the seaside and at night by the seashore. However, the line "Now I don't know where you sleep anymore" signifies the distance that has grown between them. The couple used to live under the flight path, watching the planes and the people flying past. But after the breakup, the protagonist is left alone, merely watching the planes by themselves. The repetition of the lines "By myself, by myself, by myself again" in the chorus emphasizes the loneliness and isolation the protagonist feels after their partner moved away. They are left to navigate their emotions and cope with the breakup alone. Overall, "Flight Path" captures the sadness and longing that can come with the end of a relationship. It portrays the loss of connection, the struggle to move on, and the emptiness that remains in the absence of a loved one.
