airline (n.)[airline 词源字典]: also air-line, 1813, "beeline, straight line between two points on the earth's surface" (as through the air, rather than over terrain; from 1853 and in later 19c. especially in reference to railways that ran directly between big cities in the U.S. instead of meandering from town to town in search of stock subscriptions as early railways typically did), from air (n.1) + line (n.). Meaning "public aircraft transportation company" is from 1914.[airline etymology, airline origin, 英语词源]
error (n.): also, through 18c., errour; c. 1300, "a deviation from truth made through ignorance or inadvertence, a mistake," also "offense against morality or justice; transgression, wrong-doing, sin;" from Old French error "mistake, flaw, defect, heresy," from Latin errorem (nominative error) "a wandering, straying, a going astray; meandering; doubt, uncertainty;" also "a figurative going astray, mistake," from errare "to wander" (see err). From early 14c. as "state of believing or practicing what is false or heretical; false opinion or belief, heresy." From late 14c. as "deviation from what is normal; abnormality, aberration." From 1726 as "difference between observed value and true value."

Words for "error" in most Indo-European languages originally meant "wander, go astray" (for example Greek plane in the New Testament, Old Norse villa, Lithuanian klaida, Sanskrit bhrama-), but Irish has dearmad "error," from dermat "a forgetting."
meander (v.): "flow in a winding course" (of rivers), 1610s, from meander (n.). Of a person, "to wander aimlessly" (1831), originally of persons traveling on a river (1821), perhaps influenced by confusion with maunder [OED]. Related: Meandered; meandering.
