Imagine you are onboard a ship 
docked at the Portland Harbor in Portland, ME. You decide to do some plane spotting on a very late night and catch an Airbus A320-200 from JetBlue on approach into PWM from Fort Lauderdale, FL 
This is one of those special limited time flights from FLL for the Spring 
travel season, I already covered 2 of their other special routes to Bozeman, MT and Reno, NV. However unlike those 2, I can see JetBlue seriously serving PWM from FLL.
