Spirit Airlines is currently offering cheap flights from Boston to San Diego for as low as $80 return! That works out to a cost of just 1.5 Cents Per Mile for this 5200 mile long journey.
The fare only includes a small piece of carry-on luggage, so you will need to pay extra if you want to bring a trolley onboard or check bags.
Availability at this price looks limited to the month of August 2020.
