I finally got a chance to fly as a 2P. It's definitely a nice change. The Premier Check In and Security Lines were a breeze compared to General Member lines. And it was nice to stretch out in E+.

I've got a few questions. I booked S Class seats online , but received Y Class seats at check in.

1) Is that considered an upgrade? If not, what is it called?
2) Do I receive 150% EQMs for all Y Class BIS miles flown?
3) Do 2Ps automatically receive Y Class when booking other Economy fares?

I've got more questions. But I took the Red Eye from LAX-LAS-IAD leaving last night and arriving this morning. I'm beat and can't remember my other questions.
