A passenger, airmail and light cargo air transport service operated by the State of Trenchtown. Aeropony airships travel on a looping route around the Dusts, such that any of the settlements it services can be reached from any other within a week at most, except in cases of unusual headwinds. The airships are generally quite comfortable, and fares are inexpensive; it is widely believed that Trenchtown operates the Aeropony service at cost (or perhaps even at a loss) for propaganda purposes. Tickets are often sold out at least a week in advance for some trips. Two airship routes operate regularly, designated as C (Clockwise) and A (Anticlockwise). Other destinations, particularly outside the Dusts, are sporadically available from Trenchtown. Aeropony has never had a hull-loss accident despite a number of close calls, mostly involving high winds. The airships have 12 crewmembers (8 crewponies, 4 officers) typically and carry 46 passengers. Aeropony service began in 3321.

C airships are Riches of the Abyss and Promise of Ponyism, the A airships are Beloved Trenchtown and Ponies, Unite. If an airship is delayed past its departure time at Trenchtown (usually by unfavorable or dangerous winds) the second airship can still be launched. The two airships on the route are rotated anyway for cleaning and servicing.
