For an early flight, the safe answer is to be at the airport about 2 hours before a short-haul departure (3 hours for long-haul), then work backwards by the drive time. For a 6am short-haul flight that means being there around 4am — so from central London you’re usually leaving between 2.30 and 3.15am depending on the airport. Roads are quieter at that hour, which helps, but early trains often aren’t running yet, so a pre-booked car is the reliable way to hit the timings. The table below gives a starting point for each airport.
Key takeaways
- Be at the airport ~2 hours before short-haul, 3 hours before long-haul, then add the drive.
- Bag drop closes 40–60 min before departure — that’s your real deadline, not take-off.
- For a 6am flight from central London, leave roughly 2.30–3.15am depending on the airport.
- Pre-book — early trains often aren’t running, and a fixed-price car is guaranteed to turn up.
- Add a buffer for check-in queues, security and long walks to the gate (especially Heathrow T5).
01 / RULEThe simple rule
Work backwards from your flight in three steps: be at the airport about 2 hours before short-haul (3 for long-haul); subtract the drive time to the airport; and add a small buffer for the unexpected. The deadlines that actually matter are bag drop (typically closing 40–60 minutes before departure) and the gate (~20–30 minutes before) — not the take-off time. Hand-luggage only? You can shave off the bag-drop margin, but don’t cut security fine.
02 / TABLEWhen to leave for a 6am flight, by airport
Approximate guide from central London for a 6am short-haul flight (be at the airport by ~4am). Roads are light at this hour; always allow a buffer and check live conditions.
| Airport | Approx drive (early hours) | Leave central London by |
|---|---|---|
| Heathrow (~16 mi) | 40–60 min | ~2.45–3.00am |
| London City (~9 mi) | 25–45 min | ~3.00–3.20am |
| Gatwick (~27 mi) | 50–75 min | ~2.40–2.55am |
| Luton (~28 mi) | 45–70 min | ~2.45–3.00am |
| Stansted (~37 mi) | 55–80 min | ~2.35–2.55am |
| Bristol (from city centre, ~8 mi) | 20–35 min | ~3.10–3.25am |
These are starting points for a 6am flight; for a 5am flight shift everything an hour earlier, and for long-haul add another hour at the airport. When you book, tell us your flight and terminal and we’ll set the pickup to fit.
03 / FACTORSWhat changes the timing
Nudge your departure earlier if: it’s a long-haul flight (be there 3 hours before); you have bags to check (bag drop closes early); you’re flying from Heathrow T5 or T4 (big terminals, long walks); it’s a peak holiday getaway (longer security queues); or there are roadworks or closures on the route. You can leave slightly later only if you’re hand-luggage only and have a boarding pass ready.
04 / PREBOOKDo you need to pre-book a taxi?
Pre-book (recommended for early flights)
Pros: Guaranteed to turn up at the time you set; fixed price with no surge; a driver assigned who plans around your flight; works when trains aren’t running yet.
Cons: You need to book ahead — but that’s the point at 3am.
Hail on the day / rideshare
Pros: Fine later in the morning when cars are plentiful.
Cons: Risky in the small hours — few cars, surge pricing, cancellations; no guarantee for a fixed time.
05 / TAXI OR TRAINTaxi or train for an early flight?
Once trains are running, rail is cheaper for a solo traveller heading near a station. But for the earliest flights the train often isn’t running yet, and even when it is, it’s not door-to-door and a single missed connection can cost you the flight. A pre-booked fixed-price car wins on certainty: it turns up at your door at the time you set, at a price you already know, and drives straight to your terminal. For families, groups, anyone with luggage, or any flight before about 6am, the car is usually the sensible choice.
06 / WHYWhy book a fixed-price car for the timings
Hitting an early departure is all about a car that arrives exactly when planned. A pre-booked, TfL-licensed fixed-price car is assigned to your job the night before, with the fare fixed (no surge, no night premium) and the driver briefed on your flight and terminal. As a Transport for London-licensed private hire operator running 24/7, Rushxo sends you the driver and vehicle details in advance so you can sleep, not worry.
07 / TIPSQuick timing tips
- Set your pickup off the airport arrival time (~2h before short-haul, 3h long-haul), not the take-off.
- Tell us your terminal — T5 and T4 at Heathrow need extra buffer.
- Book the night before for anything before ~6am, when trains may not run.
- Check for roadworks on your route so the driver can plan around them.
- Have documents ready to move quickly through bag drop and security.
FAQFrequently asked questions
How early should I leave for a 6am flight?
Aim to be at the airport about 2 hours before a short-haul flight, then subtract the drive. From central London that usually means leaving between about 2.30 and 3.15am depending on the airport, plus a buffer. For long-haul, be there 3 hours before.
What time should I book a taxi for a 6am flight from Gatwick?
Be at Gatwick by about 4am (2 hours before), and with a 50–75 minute early-hours drive from central London, book the taxi for roughly 2.40–2.55am. Give your terminal and flight so the pickup is set precisely.
How early should I leave for a 7am Heathrow flight?
Be at Heathrow by about 5am for short-haul (6 for long-haul, or if you prefer more margin at T5), and with a 40–60 minute early drive, leave central London around 3.45–4.00am.
How long does a taxi take to Gatwick at 4am?
Roughly 50–75 minutes from central London in the small hours, when the roads are light — quicker than daytime. Allow a buffer and confirm your exact pickup when booking.
How long is central London to Heathrow at 5am?
Usually about 40–60 minutes by road at that hour with light traffic. A pre-booked fixed-price car covers it door-to-terminal with the fare set in advance.
Do I need to pre-book a taxi for an early flight?
For anything before about 6am, yes — early trains often aren’t running and hailing a car at 3am is unreliable. A pre-booked fixed-price car is guaranteed to turn up at the time you set.
Is a taxi or train better for an early flight?
Once trains run, rail is cheaper for a solo traveller near a station. For the earliest flights the train often isn’t running, and a pre-booked car is door-to-door, guaranteed and fixed-price — usually the safer choice.
When should I leave for a Bristol Airport morning flight?
From Bristol city centre it’s about a 20–35 minute drive, so for a 6am flight (be there ~4am) leave around 3.10–3.25am. Book ahead, as the Airport Flyer is infrequent overnight.
