Are shuttle buses from LGA to EWR available 24 hours? The honest answer is no — there is no scheduled shuttle bus running directly between LaGuardia and Newark Liberty around the clock. The old NYC Airporter service that once linked the airports ceased operations in 2020, and nothing has replaced it as a timetabled, hop-on bus between the two airports.

Are Shuttle Buses from LGA to EWR Available 24 Hours? What Runs Instead
What does run around the clock is the shared-van world. Operators like GO Airlink sell shared airport transfers and advertise 24-hour pickup service to and from all three New York-area airports — you book a seat, they route a van, and the fare is quoted upfront. It is not a fixed-schedule shuttle bus in the Airporter sense, but for a 2 a.m. arrival it is the closest thing to one. If you are asking are shuttle buses from LGA to EWR available 24 because of a red-eye connection, the shared van is your steadiest bet — it is the only shared option that explicitly markets overnight pickups. Expect shared vans to take longer than a private car, since the van may serve other passengers first; budget 60 to 90 minutes between LGA and EWR on a shared ride, and confirm the pickup window when you book — some operators run on demand overnight rather than on a fixed timetable.
Uber and Lyft serve both airports at all hours, and Uber’s Shuttle product now runs fixed routes between each airport and Manhattan — LGA to Midtown stops, EWR to Manhattan stops — though those are airport-to-city routes, not airport-to-airport. For a true LGA-to-EWR trip at 3 a.m., a regular Uber or Lyft is the on-demand answer, with the usual warning: late-night airport runs can surge, so check the quoted price before you confirm.
Taxis and Private Cars: The Always-Open Option
Yellow taxis queue at both airports 24/7 and will take you from one airport to the other on the meter — no flat fare applies on this route, unlike the JFK-Manhattan trip. Ask the driver for an all-in estimate including tolls before you roll, since the route crosses tolled crossings and the meter keeps running in traffic. A pre-booked private car or van is the most predictable choice for tight connections: fixed price agreed upfront, flight tracking if your inbound is delayed, and a driver waiting at arrivals. For groups of three or more, one private van usually beats three shared-van seats on both price and time. One caution for the late-night version of this trip: the drive crosses tolled crossings into New Jersey, and those tolls land on your fare — a metered taxi at 2 a.m. with no traffic is the fastest option, while a pre-booked car is the most predictable one.
Planning an LGA-to-EWR Connection
If you are connecting between flights at different airports, give yourself at least four hours between scheduled arrival and the next departure — three if everything runs perfectly, which it rarely does on this corridor. Tell your driver or dispatcher it is an airport-to-airport connection with a hard deadline; good operators pad the route and track both flights. Keep your next boarding pass accessible and your bags carry-on if possible, because every checked bag adds 20 minutes at each end. And screenshot your driver’s number before the first flight takes off — airport Wi-Fi is not where you want to be digging through confirmation emails.
The Public Transit Route (and Its Limits)
On a budget with time to spare, public transit connects the two airports: the free Q70 bus from LGA to the Jackson Heights subway hub, the subway into Manhattan, then NJ Transit or PATH toward Newark and the AirTrain into EWR. It works, it is cheap, and it is miserable with luggage at midnight — late-night service gaps can stretch the trip past two hours. If your connection is under four hours, do not attempt it; take the car. So are shuttle buses from LGA to EWR available 24 comes down to this: no scheduled bus, but shared vans, taxis, ride apps, and pre-booked cars all run all night. If your connection is tight, the question stops being are shuttle buses from LGA to EWR available 24 and becomes which option gets you there fastest — and at 2 a.m., that is a car with your name on it, booked before you land.
