plural of airline
"Most major airlines announced a price hike for summer travel today."
In plain English: Airlines are companies that operate planes to carry passengers and cargo from one place to another.
"Many airlines have raised their ticket prices this year."
Usage: Airlines refers specifically to companies that provide scheduled air transport services, not to airplanes themselves. Use this term when discussing business entities or industry regulations rather than individual aircraft.
Derived from the late 19th-century term "aerial line," this English compound originally referred to companies operating scheduled flights along specific routes. It combines "air" and "line" to denote organized commercial aviation services connecting various destinations.
