It's nothing but blue sky for Delta SkyMiles cardholders. Delta Air Lines and E*TRADE have joined together to awards bonus miles to SkyMiles members who open online trading accounts with E*TRADE. SkyMiles members who deposit $1,000 when opening a new E*TRADE account will earn 5,000 bonus miles; members depositing $10,000 will earn 10,000 bonus miles; and members depositing $50,000 will earn 25,000 bonus miles.
