An air shuttle is a scheduled airline service on short routes with a simplified fare and class structure. No exact definition exists, but frequency is usually hourly or more often and travel time is typically an hour or less. Network airlines may operate shuttle services as one-class or no-frill services, similar to low-cost airlines.
Some shuttles are established by governments, businesses, or organizations which require a high level of service in an otherwise thin corridor. For example, the Federal Aviation Administration's William J. Hughes Technical Center in Atlantic City, New Jersey operates an air shuttle to ferry FAA employees to and from Reagan National Airport (DCA) near Washington, DC four days a week.
Certain markets support commercial shuttles. The pioneer service was the Rio de Janeiro-São Paulo air bridge in Brazil which began 5 July 1959. Other early services include the Eastern Air Shuttle, inaugurated in 1961, which offered no-frills, hourly flights connecting LaGuardia Airport in New York City with Washington National Airport and Logan International Airport in Boston, Massachusetts.
Air shuttles increasingly face competition from high-speed rail and many airlines withdraw from the market or reduce service shortly after competing high-speed rail services start.
Present-day commercial air shuttle services include:
- Aeroflot has a frequent service between the cities of Moscow and Saint Petersburg in Russia. Now increasingly competing with Sapsan service by Russian Railways along the same route.

- Air France La Navette service offers 80 flights a day from Paris-Orly Airport to Marseille, Bordeaux, Nice, and Toulouse, with a flight every 30-60 minutes.

Paris-Toulouse is France's busiest air route, while it was Paris-Lyon prior to the introduction of TGV service.
- Air New Zealand operates about 20 flights every day from Auckland to Wellington and Christchurch (3 of New Zealand's largest cities) using Airbus A320s, with up to half-hourly services during peak hours.
