Think I'm a little lost on the facts now, but I guess I was right about the wording being a little off.
What's the advantage of transferring to Skypesos if you're only ever going to be booking travel originating in the US? For the purposes of this thread, I understand the if you're booking TLV-JFK you want to use Skypesos, but if you're booking JFK-TLV, why not just use regular old Skymiles?
