I will make 2P again this year (no thanks to all those wonderful targetted promos, of which I have not received a single one

). Now, with the new Double MGM's $100 Fee offer (see thread of that title; sorry, I haven't figured out how to hyperlink yet), I can easily make 1P. However, I was 1P a couple years ago and don't remember there being much difference between 2P and 1P. But my memory is not all it should be

and so I would like to ask the FT experts if you feel it is worth $100 and an additional X-country flight to become 1P? Thanks!
