Islip, United States · North America
ISP is a one-hall Long Island alternative to the city airports — 2-hour leftover, $19.84 Long-Term across from the door, and no ticketed-pax lounge — as long as you treat LIRR as a GTC taxi hop, not a walk-up platform.
An editorial 0–10 score. The overall is exactly the weighted sum of six traveler categories — not a Google rating and not a poll.
Enter your flight for a door-to-door plan: when to leave, security, the lounge you can use and your gate. No account needed.
