Its Tuesday, May 22, 2007 and you are starting your new job today as an Air Canada Flight Scheduler.

1. Your first job is to schedule a flight from YYZ to "Porttle", a fictitious city half way between San Francisco and Seattle on the coast of Oregon just north of the California border. The city has a population roughly the same as Portland, is primarily business oriented due a base of biotechnology and pharmaceutical companies, but there is a tourist component as well.

Between connections and passengers originating in Toronto, there are between 100-130 passengers who want to travel to and from Porttle every business day and Sunday, and about 70-90 passengers on a typical Saturday.

When do you schedule this flight, using what aircraft, on what days, and why?
