✈️ Heathrow Airport (LHR) – Closest and Most Convenient

Distance to Windsor: ~8 miles Travel time: 20–30 minutes

Heathrow is by far the closest major airport to Windsor, and the best choice for most travelers. Because navigating airports often means walking between terminals, gates, and security checkpoints, some travelers use a slim running belt like this one to keep their passport, phone, and boarding pass easily accessible.

Transport Options:

  • Taxi: 20–25 minutes (£35–£50 depending on traffic).
  • Bus: Green Line 703 runs regularly from Heathrow Terminal 5 to Windsor town center.
  • Train: No direct train, but you can take a bus or taxi to Slough, then train to Windsor & Eton Central.

🚖 Best For: Short transfers, direct international flights, and stress-free arrival.

✈️ London Gatwick Airport (LGW)

Distance to Windsor: ~45 miles Travel time: 1.5–2 hours

Gatwick is farther out, but still manageable if you find cheaper flights or are arriving from Europe.

Transport Options:

  • Train: Gatwick Express to London Victoria, then change to Paddington → Slough → Windsor (multiple transfers).
  • Car rental or taxi: ~1.5 hours depending on traffic.

🚉 Best For: European travelers or budget flyers okay with a longer journey.

✈️ London Luton Airport (LTN)

Distance to Windsor: ~35 miles Travel time: 1–1.5 hours

Luton is slightly closer than Gatwick and often used by low-cost airlines.

Transport Options:

  • Train: Luton Airport Parkway → London St Pancras → Paddington → Slough → Windsor.
  • Car or taxi: Around 1 hour on a clear day.

💡 Best For: Budget-conscious travelers comfortable with public transit.

✈️ London City Airport (LCY)

Distance to Windsor: ~35 miles Travel time: 1.5–2 hours

Located in East London, this airport serves mainly business routes and has limited international flights. Some travelers also keep a small travel-size disinfectant spray like this one in their bag so they can sanitize their space on the plane or in airport lounges during long layovers.

Transport Options:

  • DLR → Bank → Paddington → Slough → Windsor (multiple transfers).
  • Taxi or Uber: Can be expensive due to central London traffic.

🏙️ Best For: Business travelers or those already staying in central London.

✈️ London Stansted Airport (STN)

Distance to Windsor: ~65 miles Travel time: 2–2.5 hours

Stansted is the farthest major London airport from Windsor.

Transport Options:

  • Train: Stansted Express → Liverpool Street → Tube to Paddington → Train to Windsor.
  • Taxi: Expect to pay significantly more due to distance.

🚫 Not Recommended unless it’s your only flight option or part of a longer UK itinerary.

Airports can involve long travel days and extended layovers, so many travelers bring a reusable collapsible water bottle like this one to stay hydrated after passing through security.

Disposable Hotel Slippers

We love hotel slippers, and some hotels give them and some do not, so we like to be prepared. Plus, the best part is, we can throw them out when we leave the hotel and make our suitcase lighter instead of carrying traditional bedroom slippers that we use at home.
