Some of the features of Skymiles (from Delta Airlines) -
Delta's SkyMiles members can book Award Travel with the ability to combine Coach, First Class/BusinessElite, SkySaver and SkyChoice travel into one ticket and save thousands of miles.
"As an example, a member who travels from Atlanta to London in a
SkyChoice BusinessElite seat and returns from London to Atlanta in a
SkySaver Coach seat may now redeem 150,000 miles versus the
previously-required 250,000 miles for the same itinerary. Or, a member
can fly from New York to Los Angeles in a SkySaver First Class seat and
return in a SkySaver Coach seat for 35,000 miles, which previously
would have required 45,000 miles."
For bookings, these are a few of the features offered to Delta frequent flyers: "
An online calendar of availability at delta.com that allows members to
shop for Award seats
Delta Messenger upgrades notification, a tool that will
automatically contact Medallion members when their complimentary
upgrade has cleared. Or, if a Medallion member is still awaiting
an upgrade to clear, Delta will automatically add the member to
the airport standby list upon check-in
Additionally, the program recently implemented technology to
automatically request an upgrade for Medallion members -- Delta's most
frequent flyers -- when they make an eligible reservation at delta.com,
with Delta reservations, or with a travel agent."
"The award-winning Delta SkyMiles program offers members multiple
mileage-earning opportunities when flying Delta, Delta Shuttle(r), the
Delta Connection(r) carriers, Delta AirElite(r) and other SkyTeam(r)
airlines. Additional mileage-building opportunities are offered through
more than 100 partners such as the Delta SkyMiles Credit Card from
American Express, SkyMilesShopping.com, participating hotels, car
rental companies, telecommunication services, restaurants, retailers
and more."
