Taxi vs Parking at Heathrow
Driving yourself means paying for airport parking for every day you're away. For anything longer than a couple of days, a return taxi from Slough often works out cheaper than parking — and you don't need to find a space or catch a shuttle bus back to the car.
Taxi vs Train
Rail fares are per person, and there's no direct train — you change at Hayes & Harlington. For two or more people, or anyone with luggage, the taxi is usually cheaper per person and much simpler.
When to Leave Slough
Allow around 15–25 minutes for the drive, plus extra in the morning and evening rush hours. For long-haul flights, airlines usually recommend arriving 3 hours before departure; for short-haul, 2 hours. Tell us your flight time and we'll suggest a pickup time.
