In my experience, that isn't the case at MCO. The curbisde lines are MUCH shorter, at least they have been for me. The system they have for checking luggage at MCO is a little bass-ackwards if you ask me. At least at the SW counter. First you check your luggage at the counter, and then you have to take it over to the xray. At curbside, they handle the whole thing. Well worth the $2 tip per bag.
