The 737-700 is part of the Next Generation (NG) Boeing 737 family and the workhorse of Southwest Airlines' fleet, underpinning the airline's point-to-point business model in the US.

Fleet Rarity

Very common; Southwest is the largest 737-700 operator worldwide.

Record Flights

Used frequently on high-frequency short-haul US routes; not notable for ultra-long-hauls.

Future Outlook

Gradual phase-out in Southwest's fleet in favor of 737 MAX-7 over the coming decade, but still widely active.
