Port City Air

What Port City Air does

Port City Air is a privately held, full-service Fixed Base Operator (FBO) located at Portsmouth International Airport (KPSM) in Portsmouth, New Hampshire, founded in 1997. The company provides 24/7/365 aviation ground services — fueling (with direct and contract Jet A rates), ground handling, hangar rentals, aircraft maintenance, international tech stops, and passenger and crew amenities — to four primary customer verticals: business jet operators, scheduled and charter commercial airlines, cargo freighters, and U.S. and foreign military operators. The company maintains a FAR Part 145-certified Repair Station offering turbine and piston maintenance for fixed-wing aircraft and helicopters (including authorized service for Airbus Helicopters and Leonardo Helicopters) along with a full avionics shop. The business combines transaction-based service fees (fuel, handling, maintenance labor) with recurring hangar rental, sold through direct sales (phone, email, dedicated military concierge team), field sales for enterprise/government accounts, and a self-serve reservation channel via the Flight Bridge online platform. Through 2020, the company expanded its footprint by launching 24/7 mobile AOG services across all of New England and completed a major terminal expansion (55,000 sq.ft commercial/international terminal with a second jet bridge) in 2021. The company is a member of the Paragon Network of elite FBOs and partners on-field with Air New England (regional air charter), Great Circle Catering (inflight catering), and Seacoast Aviation (air cargo). Capital intensity is high — 120,000 sq.ft of heated hangar space, a 12-vehicle refueler fleet with 270,000+ gallon Jet A capacity, 150 acres of unrestricted weight-bearing parking apron, and de-icing equipment reaching 78 feet — enabling handling of widebody commercial, heavy cargo, and military aircraft typically associated with larger hub airports. The company employs 11-50 staff, with an unusual 7+ year average tenure relative to FBO industry norms.
