Average 2 days: The typical incubation period for influenza is 1—4 days (average: 2 days). Adults shed influenza virus from the day before symptoms begin through 5—10 days after illness onset. However, the amount of virus shed, and presumably infectivity, decreases rapidly by 3—5 days after onset in an experimental human infection model.

...: The incubation period for the flu is between 1-4 days. This means that people can pass along the flu to others before they even know they are sick, as well spread the flu to others for 5-7 days after becoming sick. Washing your hands often and getting the flu vaccine are ways you can protect yourself from the flu.

Ebola Virus: Per CDC, incubation period is 2 to 21 days w average of 8 to 10 days. A person will not transmit disease if they are asymptomatic and don't have a fever. If a person were on a lengthy flight or multiple flights- theoretically the person could evolve from incubation to active disease. This is why many international airports have instituted medical screening upon entry into the country.
