That was speculated but not proven. If you look at some analysis of that indecent with the monkeys by top virologists and infectious disease specialists they aren't so sure it was airborne.

Transmission of Ebola virus from pigs tonon-human primates

Ebola viruses (EBOV) cause often fatal hemorrhagic fever in several species of simian primates including human. While fruit bats are considered natural reservoir, involvement of other species in EBOV transmission is unclear. In 2009, Reston-EBOV was the first EBOV detected in swine with indicated transmission to humans. In-contact transmission of Zaire-EBOV (ZEBOV) between pigs was demonstrated experimentally. Here we show ZEBOV transmission from pigs to cynomolgus macaques without direct contact. Interestingly, transmission between macaques in similar housing conditions was never observed. Piglets inoculated oro-nasally with ZEBOV were transferred to the room housing macaques in an open inaccessible cage system. All macaques became infected. Infectious virus was detected in oro-nasal swabs of piglets, and in blood, swabs, and tissues of macaques. This is the first report of experimental interspecies virus transmission, with the macaques also used as a human surrogate. Our finding may influence prevention and control measures during EBOV outbreaks.

Under conditions of the current study, transmission of ZEBOVcould have occurred either by inhalation (of aerosol or larger drop-lets), and/or droplet inoculation of eyes and mucosal surfaces and/orby fomites due to droplets generated during the cleaning of the room.Infection of all four macaques in an environment, preventing directcontact between the two species and between the macaques them-selves, supports the concept of airborne transmission.
From the study- where they acknowledge the monkeys could have encountered droplets from cages being cleaned and/or a fomite source. I guess we will have to watch and see how the virus behaves the longer the outbreak continues. There is also the likelihood that going airborne will reduce the severity of the illness.
