When should I leave for the airport? The complete 2026 guide

Forget the "arrive 2 hours early" rule. Use this complete guide to calculate your exact departure time based on traffic, security wait times, bag drop, and your specific flight type.

"Arrive 2 hours before your flight." It's the most common piece of travel advice - and it's also the most useless. Two hours is fine for a sleepy Tuesday afternoon flight from Bordeaux. It's wildly insufficient for a Friday evening departure from Schiphol.

Here's the complete 2026 framework for calculating when you should actually leave for the airport.

Step 1: how long does your flight type need at the airport?

Start with how long you need at the airport before boarding closes:

Schengen + hand luggage only: 60–75 minutes
Schengen + checked bags: 90–120 minutes
Non-Schengen (e.g. UK, US): 120–150 minutes
Long-haul intercontinental: 150–180 minutes

Step 2: add airport-specific factors

Some airports are notoriously slower than others. As a rough additional buffer:

Schiphol (AMS): +20 minutes during peaks
Heathrow (LHR): +15 minutes
CDG Paris: +20 minutes (Terminal 2E especially)
Frankfurt (FRA): +10 minutes
Brussels (BRU): +10 minutes morning peak
Charleroi (CRL): +10 minutes Friday evenings

Step 3: factor in the drive (or train, or bus)

This is where most people miscalculate. Use Google Maps' "leave at" feature, but always look at the highest end of its predicted range - Google tends to be optimistic.

Add 10 minutes for parking + shuttle if you're driving and parking off-site, and 5 minutes if you're using express parking.

Step 4: the buffer

Add a personal buffer based on how stressed you get at airports:

Calm traveller: 10 minutes
Average: 20 minutes
Anxious: 30+ minutes

Worked example

You're flying Schengen with checked bags from BRU on a Friday evening. You live 35 minutes from Zaventem in normal traffic, but it's a Friday so add 20 minutes. You're a calm traveller.

Time at airport: 105 min. Drive: 55 min. Buffer: 10 min. Parking: 10 min. Total: 3 hours before scheduled departure.

Or just let GateBy do the maths

This is why we built GateBy. Instead of guessing, you get a single notification that says "Leave at 04:12" - calculated live based on your flight, the airport, current traffic and your luggage type.
