their upcoming concerts are literally just a few days away from each other located in different countries. this one is still in a week. what do you expect them to do? go to the us a week earlier and just be in their beds for a week? lol. and blackpink are probably the idols who has rode a plane the most these last years. surely, they already know how to cope with jet lag.
ofcourse you would take 2 days minimum to recover. i do too since i only fly once a year. lol
