Plan to be at Logan two hours before a domestic departure and three hours before an international one, then add your drive time on top, not inside it. From Back Bay that drive is 15 to 20 minutes off-peak and 35 to 45 in rush hour; from Newton it can double. The mistake that misses flights is using an off-peak map estimate for a peak-hour trip.
Below are the real departure numbers by neighbourhood, hour and season, from years of running the same routes.
How Early to Leave for Logan: The Tables
Build your departure time from three numbers: terminal buffer, drive time, and a margin for the day’s conditions. The buffer is fixed; the drive time is not.
| Origin | Off-peak drive | Rush-hour drive |
|---|---|---|
| Back Bay / South End | 15–20 min | 35–45 min |
| Seaport / Financial District | 10–15 min | 25–40 min |
| Cambridge / Kendall | 20–25 min | 40–50 min |
| Brookline | 20–25 min | 45–55 min |
| Newton | 25–30 min | 50–70 min |
| Lexington / Route 128 | 30–35 min | 60–75 min |
| MetroWest (Framingham) | 40–45 min | 75–90 min |
| North Shore | 30–40 min | 50–65 min |
By Hour: Rush Windows That Double Your Drive
Boston’s congestion is sharply time-boxed rather than evenly spread:
- 6:30am to 9:30am inbound, worst from the western suburbs.
- 3:30pm to 7:00pm, the longest and least forgiving window of the day.
- Friday afternoons run worse than other weekdays and start earlier.
- 10am to 2pm and after 7:30pm are the clean windows.
The same Newton-to-Terminal-E trip is a comfortable 30 minutes at 11am and a stressful 70 at 5pm. That is not traffic bad luck; it is the schedule.
By Season: Snow, Summer Fridays & Holidays
Add to your drive estimate in three seasons. Winter snowfall adds meaningfully to every route and more to suburban ones, which is why winter pickups are dispatched with automatic buffers under our winter reliability protocol. Summer Friday afternoons push Cape-bound traffic through the same corridors. And the Thanksgiving and December holiday weeks compress peak conditions into the middle of the day.
Tunnel Logic: Ted Williams vs Sumner vs Route 1A
Which harbour crossing you use changes the trip more than which street you start on.
- Ted Williams Tunnel is the default from the Mass Pike, Seaport and points west, and it feeds the airport directly.
- Sumner Tunnel serves northbound traffic and is the slower option during its own peak and any maintenance period.
- Route 1A is the surface approach from the north and East Boston, and often the quickest option from East Boston.
A chauffeur picks the crossing live based on conditions. That choice alone regularly saves 15 minutes on a bad afternoon.
Security & Check-In Buffers by Terminal
Two hours domestic and three international are the baseline, but Logan’s terminals do not behave identically. Terminal E handles international departures and runs the longest check-in and security sequence. Terminals B and C carry heavy domestic banks with sharp morning peaks. Terminal A is generally the quickest through security outside those peaks.
If you are checking bags, travelling with children, or flying internationally, take the upper end of the buffer. The terminal-by-terminal detail for arrivals is in our Logan terminal guide.
Building Your Personal Departure Time
Work backwards in this order:
- Flight departure time.
- Minus the terminal buffer: 2 hours domestic, 3 hours international.
- Minus the drive time for your neighbourhood at that hour, from the table above.
- Minus 10 to 15 minutes for loading and the unexpected.
A 6:00pm international departure from Newton therefore means a pickup around 1:45pm, not 3:30pm. That gap is where missed flights live.
Suburban travellers can check their specific route on our Newton, Cambridge and Lexington pages.

Four Timing Mistakes That Miss Flights
- Using a map estimate from the wrong hour. Checking the drive at 9am for a 5pm departure is the most common error, and it is routinely wrong by half an hour or more.
- Counting the buffer as including the drive. Two hours means two hours at the airport, not two hours from your front door.
- Forgetting the walk. Check-in queues, security and the gate walk are real minutes that sit outside the drive estimate entirely.
- Treating winter like any other season. Snow changes suburban routes most, and the western suburbs most of all.
Suburb-Specific Departure Notes
Western suburbs feed through the Mass Pike, so a delay there affects every origin behind it; Newton and MetroWest departures are the ones most often underestimated. North Shore origins use Route 1 and the Sumner approach and move better in the morning than the evening. East Boston is the shortest run in the market but still needs a buffer at peak, because the airport loop itself congests.
One final note on buffers: they are not wasted time. An early arrival at Logan means a seat, a coffee and a calm boarding. A tight arrival means a sprint, and occasionally a rebooking fee that costs more than the entire car service. The buffer is the cheapest insurance in air travel.
Logan Departure Timing FAQs
How long before a flight should I leave Boston?
Be at Logan two hours before a domestic departure and three hours before an international one, then add your neighbourhood drive time on top. From Back Bay at rush hour that means leaving roughly two hours forty-five minutes before a domestic flight.
How long is security at Logan Airport?
It varies by terminal and time of day. Terminal E international departures run the longest sequence; Terminals B and C peak with their morning domestic banks. Taking the upper end of the standard buffer covers normal variation.
What time is traffic worst to Logan?
Between 3:30pm and 7:00pm on weekdays, and earlier on Fridays. The morning peak runs 6:30am to 9:30am and hits western-suburb routes hardest.
How early should I leave for an international flight at Logan?
Allow three hours at Terminal E plus your drive time. From Newton or MetroWest at peak hours, that can mean a pickup four and a half hours before departure.
Which tunnel is faster to Logan?
The Ted Williams Tunnel is usually faster from the Mass Pike, Seaport and the west. The Sumner serves northbound traffic and is slower in its own peak. Route 1A is often quickest from East Boston and the north.
Does a car service pick the route for me?
Yes. Your chauffeur selects the crossing and route live based on conditions on the day, which is where most of the time saving actually happens.
How much extra time should I allow in winter?
Build in a meaningful additional buffer during snowfall, more from suburban origins. Winter airport pickups with Riding Loft Limo are dispatched with that buffer applied automatically.
