Because they produce less drag, better acceleration, better fuel consumption, and produces less noise, both flaps 1 and 5 are used by Airlines.
Flaps 1, 5 and 15 are normal takeoff flaps but 15 is rarely used. Flaps 10 is not a normal flap setting for takeoff. The flaps and takeoff thrust settings are all calculated by the load controllers based on weight, weather, runway length and obstacle clearance. One day you might use flaps 1 and the next on the same runway use flaps 5.
American Airlines and Westjet almost always use flaps 1 for take off.
Continental, United, SWAT, KAL and Alaska pretty much always use flaps 5 for takeoff.
Flaps 25 takeoffs are regularly used in Rio de Janeiro and common for Maui.
