My friend Sean Ness received the above Delta Weekly Fare Specials email this morning. Note that one of the (erroneous?) specials is a $69 each-way fare from Oakland to San Francisco. That's a 31 mile trip airport to airport across the Bay Bridge, so perhaps it would actually be cheaper to fly than, say, take a taxi?
