Delta's new airline mileage deal is a deliberate attempt to reward its high-spending customers and take from the unwashed 99 percent -- further widening the gulf between the haves and the have-nots.
Tickets to Europe that were $500 two years ago, are now $1,000. If you look closely at the breakdown, you'll see that the base ticket price is still the same $500; it's the increased taxes, security fees, fuel surcharges, etc. that account for the whopping additional $500!
My advice is to start planning ahead as much as you can so you can start to redeem your American and US Airways miles as quickly as you can.
