Hi, we will be coming from Fort William next July 19th and flying out of Inverness airport. We will not have a car. I am assuming we can take a morning bus from Fort William (although it's too early to check yet) and hope to spend the afternoon in Inverness, perhaps taking a Loch Ness cruise. We have a 5:30pm flight back to London and I'm wondering what would be the best way for 3 of us to get from the city to the airport? Also, how early do we have to be at the airport for a domestic flight? Thank you!
