I've haven't had to show pic ID at the gate in years...it's not hard at all for that to work.
I didnt say at the Gate. I imagine a person can do OLCI and have their friend purchase a tkt on a different flight and get thru TSA! that way, but lately Ive noticed the GAs looking at the BP before swiping it, is it to make sure that TSA has its stamp on it, I wouldnt want to have a GA question me how I got thru TSA w/o their stamping my BP.
Then again theres not enough $$ involved for someone to put themselves at risk ,IMO. Also you will ned to provide a way for the other person to get back to where they flew from. It might work say if I was heading to CLE and I fly as You and then you continue on from CLE and I will fly back Home after you have flown back to CLE. But the % of something like that working out is slim, so now how do I get back home if I dont want to be in CLE till you return?
So although in Principal it might be workable, its not a real option since of the problems of getting the person flying the 1st leg back home, chance that the GA will spot no TSA marks on the BP, and finding someone to actually be willing to fly the 1st and/or last segments for little or no $$.
