I'm not familiar with flying from Portland, Oregon, to Detroit, but I need to acquire some data for a situation I'm involved in. Based on Google Flights, I cannot find a single direct flight from Portland to Detroit in the future. I am not sure if this is due to COVID, or if this is just the normal situation.
Is there anyone who has flown this route before and can share some insight?
If there was no direct flight form Portland to Detroit, I would be a bit surprised. Detroit is a major airport. Portland is medium sized airport, and I would expect at least 1 or 2 direct flights to Detroit a day.
Is there a website where I can search if there were direct flights in the past?
