i heard that you can get a free ticket if you earn 100,000 miles, does this mileage has to be accumulated in 1 yr or it can spread over 5 yrs?

Better than free ticket, I have 36,000 or so now, I can upgrade from Evergreen Deluxe to business class, woo hoo!

By the way, for about $200 extra, Evergreen Deluxe is really worth it. Only 2 seats across on the outer rows and more room/bigger seats, video screen (not sure about coach also) plus you get a multiple of miles (150% for example), so you earn miles faster.
