Okay great, that makes a lot of sense.

1) BG2 doesn't really mean anything for me as long as I have E+
2) PA isn't a big deal for me. I have Global Entry so not concerned about getting through security faster. Priority bags not a big deal since I rarely check.
3) Rarely check
4) CPU not too likely.
5) Agreed with subscription
6) So just having it gives more availability?

Sounds like, for me, the big advantage of having the Explorer is the chance at #4 (not sure how likely, I think I got very lucky this trip) and #6 but I think that's only for economy right?
