I am catching a flight from T6 on a Wednesday at 8 am. I'll be coming from downtown, and debating between an uber direct from my hotel or making my way over to Union Station for the Fly Away bus. Will traffic be bad at around 6:30 am on a Wednesday going from downtown to the airport? Is it worth the extra transfer to use the Fly Away bus since it can access the terminals using the inner roadway? Or is it basically a wash? Thanks!
