Though it's a $5 flat fare from the LIRR to ISP, if he just takes a cab from the line at the airport to the train station, it will run between $12 and $15. If he calls and orders the cab, it's only $5. There's a phone in the airport that connects to Village Taxi, or he can call at 8003711058. Sunset also charges the flat $5 for a pickup, but I don't have their number handy. Colonial (6315897911)did run a shuttle for the same $5, theoretically connecting to all LIRR departures; I found them unreliable, but if it's there, he can grab it. Train to Penn is $9.50 peak, $6.50 offpeak. Except for rush hour express trains, trip is scheduled to take about 85 minutes, but it often takes longer. Good news is that since Ronkonkoma's the first stop, you can always get a seat.
