After arriving at the airport, you might feel tempted to go to the shortest security screening line.
However, a short line doesn't necessarily indicate a fast one. Take a look at who makes up each line.
A bunch of traveling business people will probably move through security faster than a family that only travels once a year. As an extra tip, move to the sidelines at larger airports.
New and casual travelers will often just walk straight ahead, making the outer security queues much more efficient.
