You have to consider many options to find the best fare. I booked flights departing 100-miles away to save $600. One-way frequent flier tickets can be a deal with a paid return. When I was working in Afghanistan I discovered RT from Dubai or Delhi was around $400 less than starting in the states and included a free second U.S.A. city. I could go on and on…
I booked a flight 3 hours away in Toronto saving $4K on a business class ticket. Flying half way around the world in coach really sucks.
