Abdul Mutallab had purchased ‘one way tickets’ because he wanted to martyr himself by detonating his PETN bomb in his undies aboard Flight 253.
Nigerian officials said the man's round-trip plane ticket was bought on Dec. 16 in Accra, Ghana, for $2,831 in cash, presumably by Abdulmutallab himself.
He was flying Coach. I just did a round trip search for Lagos to Detroit. Four of the cheap tickets were each $ 1,727.11 USD, two on Air France (via Paris) and two on Delta (KLM) via Amsterdam.
I think they knew that a one way ticket for cash would be a red flag, so they purchased a round trip ticket.
So many folks just repeat the MSM about the one way ticket.
