That's why I think....

air travel should be like in the 'Fifth Element'. You show up to the airport, they drug, stick you in a sleeping pod, and off you go.

Passenger finds box cutters on plane at DIA

'KUSA - A United Airlines flight from Denver to Dallas was delayed two hours Tuesday after a passenger found box cutters in the seatback pocket in front of her.

That is according to Transportation Security Administration spokesman Darin Kayser.

United Flight 490 was taxiing on the runway at Denver International Airport at 12:30 p.m. when the box cutters were found.

"The passenger notified the flight attendant, who told the pilots, who called authorities," said United spokesperson Megan Mccarthy.

She says the pilot aborted takeoff and returned to the gate.

TSA officials re-screened the 138 passengers and swept the plane. No other weapons were found, according to Kayser. The plane took off for Dallas at 2:25 p.m.

United says the plane came into DIA from LaGuardia Airport in New York City. Passengers got off and it was reloaded for the flight to Dallas.

When asked how the box cutters could have gotten on board, the TSA spokesman told 9NEWS he would not speculate.'
