I'm not even sure if that is what you call him/them. The people outside the doors at the airport where you can dump your luggage. We have never used them and considering it this trip. We have 2 elderlies with us and I have hyperextended my knee recently so considering having the husband drop us at our nearby airport curbside and getting rid of the luggage. Is there a cost or is it just a tip, if so...I don't believe after all these years and threads I have read I am asking this, how much? I have one of those husbands who thinks he is OJ Simpson booking it from the parking garage hauling luggage over to the check in desk...forgetting that the rest of us can't keep up with him. I am assuming just give them the conf # and they tag/take your luggage just like inside.
