Also as you board/deplane your commuter flight...ask other deadhead pilots and FAs if they are going to Kew Gardens. I shared many a 12 dollar cab ride with 1 or 2 others. Catch is that when you call the cab you need to tell him you have x riders to ensure you can all split the 12 fee otherwise they will charge each of you if you do it on the fly at the curb. Then some will also charge you more if you want more than one location for drop off. Just clarify the conditions as you get into the cab.
