Does Delta allow you to fly on one-way ticket?

[jesm]

True.
My wife was initially denied boarding by Delta last month in Atlanta as we were returning to our home here. Their computer refused to issue her boarding pass as it could not identify her holding a return ticket back to usa. Of course not, as we were returning not starting our joyrney, so A few minutes of explanation to the counter agent and he was able to manually issue her boarding ticket. He blamed the hassle on TSA regs and 9/11.
BS I say.
