This is travel life, nothing else.
My bag got to Rwanda 4 days late (offloaded in BRU due to weight even though I'm *G and flying paid J)...the day I was leaving. Went to high level gov't meetings in the jeans, sneakers and t-shirt I flew over in all the way from YVR.
Bag arrived the morning I was leaving.
You really have to take this stuff in stride.
