I'm a bit confused with the united.com site (call me lay or crazy) I don't get it, is the 75,000 milled needed for econ seat EWR-TLV a round trip, or its one-way, and I need 150,000 miles for a round trip on economy? So for the the meshugena couple to get the full round-trip free, we need to rack up 300,000 miles. Can any one please explain us?
