Baggage: to interline or not to interline?
*A award travel upcoming. Next week, I fly with no layovers:
PHL-LAX (US) F
LAX-ICN (OZ) F
ICN-BKK (TG) C
BKK-HKG (TG) F
My return, again with no layovers:
HKG-BKK (TG) F
BKK-ZRH (TG) F
ZRH-JFK (LX) F
Should I interline my bags all the way through each way? Or am I asking for lost baggage if I do?
