Can you provide a link to the information about construction on the LIRR? In the unlikely event that this construction causes a suspension of service between Jamaica and Penn Station, you can always take the "E" subway from Jamaica to Penn Station. The subway takes about 40 minutes and costs $2.25 per person if a Metrocard is used; or $2.50 if a single-ride ticket is used. The LIRR takes abot 20 minutes for the same trip, but costs $6.25 per person during off-peak times (trains arriving Penn Station weekdays after 10:00 AM).
The AirTrain costs $5.00 per person from JFK to Jamaica.
