It sounds strange to me that they say "This is the Indigo Service 204 to...", where all the others that I've heard say "Castles Express X21 service" or "Angel 21 service"
Not that it actually makes any difference, it just doesn't seem grammatically correct to me
Maybe because theres more than 1 service under that brand?
