Singapore Changi Airport vs London Heathrow Airport

Overview

Repeatedly ranked the world's best airport with Jewel, free city tours, and exceptional transit experience.

Jewel and terminal layout

Jewel Changi opened in 2019 as a standalone lifestyle complex linked to Terminal 1, featuring the 40-metre HSBC Rain Vortex — the world's tallest indoor waterfall — plus Canopy Park, hedge maze, and 280+ shops and restaurants. It is accessible to both departing passengers and visitors without a boarding pass.

Terminal 1 serves Star Alliance carriers including Singapore Airlines long-haul. Terminal 2 handles low-cost and regional carriers. Terminal 3 is SIA's primary long-haul terminal with the best SilverKris lounges. Terminal 4 is a compact automated terminal for regional LCCs.

Lounges at Changi

Singapore Airlines SilverKris Business and First lounges in T2 and T3 are among the world's best, with buffet dining, a la carte options, and shower suites. Star Alliance Gold and business class passengers access these on SIA and partner flights.

Priority Pass holders can access Plaza Premium and SATS lounges across terminals. The Qantas First Lounge in T1 is excellent for oneworld First passengers. Pay-per-use lounge access typically costs SGD 50–70.

Overview

London Heathrow is the UK's primary international hub and Europe's busiest airport by passenger volume, handling around 83 million travellers a year across four active terminals. Its strength is unmatched global connectivity — particularly long-haul routes to North America, the Middle East, and Asia — and a lounge portfolio that includes British Airways' Concorde Room, Virgin Atlantic's Clubhouse, and the American Express Centurion Lounge. Weaknesses are well documented: terminal sprawl, occasional ATC-related delays, and a passenger experience that can feel transactional outside premium cabins.

Terminal guide: which airline flies from where

Terminal 5 is British Airways' fortress hub — virtually all BA long-haul and short-haul flights depart from T5, along with select Iberia services. If you hold BA Gold or are flying Club World or First, the First Wing check-in and Concorde Room are here. Terminal 3 hosts Virgin Atlantic, Delta, Air France, KLM, and several Middle Eastern carriers; it is also where the Amex Centurion Lounge and Virgin Clubhouse sit side by side. Terminal 2 is the Star Alliance terminal (Lufthansa, Singapore Airlines, Air Canada, United on some routes). Terminal 4 handles Cathay Pacific, Malaysia Airlines, Qatar Airways on select rotations, and Royal Jordanian.

Inter-terminal transfers require leaving security unless you are on a through-checked connection with a minimum connection time built into your ticket. The free transit train between terminals runs airside at T2/T3/T5; T4 requires a bus. Budget 60–90 minutes for a landside terminal change.

Getting to and from Heathrow

The Elizabeth line (opened 2022, fully integrated 2023) is now the best value rail option for most central London destinations, running from all terminals through Paddington, Liverpool Street, and Canary Wharf. Off-peak fares are substantially cheaper than the Heathrow Express. The Heathrow Express remains the fastest option to Paddington at 15 minutes but carries a premium fare (£25+ one-way). The Piccadilly line is the budget choice — slower but direct to Zone 1.

National Express and other coach services connect LHR to cities across the UK. Black cabs and ride-hail operate from all terminals; expect £50–£80 to central London depending on traffic. Driving is discouraged: drop-off charges apply and parking is expensive.

Lounge access at Heathrow

Heathrow has the strongest lounge selection of any UK airport. British Airways operates Galleries Club, Galleries First, and the Concorde Room in Terminal 5 — the Concorde Room is restricted to same-day BA First passengers and BA Gold/Gold Guest List members on long-haul Club World. Virgin Atlantic's Clubhouse in Terminal 3 is among the best business lounges in the world, with a la carte dining and spa treatments. The American Express Centurion Lounge in T3 offers cardholders a Michelin-chef-designed menu but no runway views.

Priority Pass and DragonPass holders can access Plaza Premium, Aspire, and Club Aspire lounges across terminals, though quality varies and peak-time entry is not guaranteed. Day passes typically cost £40–£55 walk-up.
