Denver resident for nearly 6 years; ER member for nearly 6 years

miles needed for award = A (15,000 domestic is great!)
routes = A
airline partners = F
award availability = A (only redemmed once so far)
mileage promos = A (double miles when new routes start)
customer service = B (A for corrective action; D for not putting more effort into notifying member -- ER reinstated my miles after they expired unexpectedly. program rules changed after i joined in 2002 and i was not notified of the new 2-year expiration rule. legacy carrier would likely not have even considered helping.)
