I did it!

I never before went far enough down the Flight Selection screen to click on the price itinerary button.

I do have a few outstanding questions.

1. For economy class, does the seats with the green "premium" refer to full fare economy, and the blue seats refer to discounted econonmy?

2. Can one look at economy and business class simulatenously, in terms of seat selection - rather than picking first economy class, and then business class, for the flight selection, before the seat selection option is clicked on?

3. Does the seat selection in any way tell us which business class seats are available for upgrade, and which are only open for revenue purchase (separate from the J_C_ information seen in the table on the flight selection screen)?
