Since 2001, I have shipped our luggage (not the actual piece of luggae!!) everywhere we travel -- NYC, Siesta Key, Disney, etc. I will not stand in airport lines, file lost luggage reports (waited over an hour at MCO the last time I flew with luggage) or just wait in general. Once they started charging for luggage, I def. wasn't traveling with my luggage because it's not like their service improved. At least with UPS, I'm still paying but the service is incredible. I do not like running around finding the carousel where my luggage is suppose to arrive, waiting for it to be thrown onto the carousel (mine always seems to be the last off the plane) or worry about it and stand in another line when it's been "lost" or placed on the flight after mine. The excuses the airlines use are long! So I ship! The cost is relative to my vacation time. UPS has never falied me yet and I just called the hotels ahead of time, told them I'd have boxes arriving, they put it in the luggage room and I just tip well. I walk off a planr, into a cab, rental car, etc and arrive at my hotel and sit at the pool/beach as others are running around getting their luggage.
When I was in NYC and shopping, instead of carrying the purchases from downtown to uptown, I just found a shipping place in SoHo and immediately shopped my purchases home. I was with friends who had also been shopping and we just all split the cost and had it delivered to one of our homes. We could then continue sightseeing, shopping. eating without lugging the purchases.
I only travel with carry on and refuse to check any luggage -- the system is awful and though I know most of it is all the updated and necessary security, I just won't monopolize my vacation with all this little stressful stuff. Originally the bagged fee was due to the outrageous gas prices -- well gas is now 1/2 the cost it was and the airlines haven't taken away the baggage fee and the baggage service hasn't improved.
