It has been referenced repeatedly by commentators attacking the U.S. government for missing red flags about Abdulmutallab. See for example this Michael Gerson column in the Jan. 6 Post ("Airline attack shows Obama's listless approach to terrorism") and this Michael Mukasey Wall Street Journal effort ("The president's job is not detecting bombs at the airport but neutralizing terrorists before they get there.")
In a typical case on Dec. 28 -- when the accurate information was already available -- CNN anchor Erica Hill asked: "So, just how did a guy on a terror watch list with a one-way ticket paid for in cash, with no luggage ... manage to board a U.S. airliner and allegedly try to blow it to pieces? Simply put tonight, who screwed up?"
And here's Rush Limbaugh on Friday: "When a 20-something Muslim male buys a one-way ticket with cash and has no luggage, that's not a dot. That's a fire alarm! He may as well have "I'm a terrorist" taped on his T-shirt."
But published reports on Dec. 28 cited the conclusion of the Nigerian government that Abdulmutallab had a round-trip ticket to Detroit. It had been purchased in Ghana on Dec. 16 for $2,831, according to the AP, citing Civil Aviation Authority director Harold Demuren. His return date was found by the Nigerians to be Jan. 8. (A Dutch government report described by the International Herald Tribune on Dec. 31 also said Abdulmutallab had a round-trip ticket, but it's not clear whether the Dutch were simply relying on the Nigerians' conclusion.) A full account of Demuren's comments can be found in the Nigerian newspaper The Nation here.
While the New York Times published a correction on Dec. 30 saying it had erroneously reported Abdulmutallab's ticket was one-way, many outlets that have mentioned the one-way ticket haven't run corrections.
So where did the false meme come from? Anonymous U.S. government sources. And unless there's classified information suggesting otherwise, those sources were clearly mistaken.
The first citation of a "one-way ticket" we could find is a report on Christmas day by MSNBC (cached version here): "Federal officials identified the man as Umar Farouk Abdulmutallab, 23, of Nigeria, who was traveling one way, without a return ticket."
Another early reference is in the Dec. 26 edition of the New York Daily News: "Officials said Abdulmutallab was traveling one way, without a return ticket."
MSNBC's Pete Williams tells TPMmuckraker: "Though there were federal officials who initially said it was one-way, we've [been] saying since that it was round trip, which it clearly was."
But there are a whole lot of media consumers out there who believe Abdulmutallab came to Detroit on a one-way ticket.
The "one-way ticket" has been cited by CNN, Fox, Time, Newsweek, the AP, the Washington Post, the New York Times, the Boston Globe, Gannett News Service, the Pittsburgh Tribune Review, the Sacramento Bee, the Globe and Mail, the Washington Times, Congressional Quarterly and many other outlets, according to a review by TPMmuckraker.
The Today Show's Matt Lauer even asked about the one-way ticket in a question to Homeland Security Secretary Janet Napolitano (who did not address the matter in her answer).
The only substantiated reference to a one-way ticket in we could find is the statement by a Ghanaian official last week that Abdulmutallab purchased a one-way ticket in cash from Accra, Ghana, to Lagos, Nigeria. That was in addition to the purchase of the ticket from Lagos to Detroit via Amsterdam, according to Deputy Information Minister Samuel Okudzeto-Ablakwa, quoted in the Wall Street Journal. The Journal says Abdulmutallab took Virgin Nigeria flight 804 from Accra to Lagos on Dec. 24, before getting on a plane en route to Amsterdam.
There are few signs that the "one-way" meme will die any time soon.
The AP, which two weeks ago reported the correct information from Nigeria, ran a story Friday ("Experts say terror watch lists have limited uses") stating that Abdulmutallab purchased a one-way fare.
