Oh well, I'd rather ship those 3 pieces of laggage we are going to take and go with this route...
Another thing - did anybody tried it with checked in bags? Will they drop them off in CLT if we not board or they are going straigh to GSP? Or, lets rephrase, will I be able to get them after all (I'm even ready to drive 1 h and be there prior to plan as it's 1 h drive and flight has 3 h connection time).
