"Delta's SkyMiles"

Wow! Delta SkyPESO? You must be joking.

SkyPESO is the worst of all. Limited Seats, no one-way booking, and you never get the lowest cost fare (it's only for advertisement purpose) even 10 months out for International travel.

And any date change will incur the MAXIMUM cost among all airlines, like USD$150. American Air, Continental etc does not charge 1 cent for date changes.

Stay away from Delta. At all cost.
