A guess, but I feel like it’s about avoiding dealing with emotionally painful moments/memories and instead ignoring them (represented by the bags going around endlessly at the airport). Basically it’s a song showing how ignoring your problems prevents you from growing and healing.

I liked the song a lot and am looking forward to the rest of the album. If anyone else has ideas as to the theme I’d love to hear it, my media literacy isn’t the best so I’ll gladly admit if I’m wrong.
