In short
Heathrow (LHR) is the UK's main long-haul hub with four terminals, the Elizabeth line and Heathrow Express rail links, and the country's best airline lounges including BA's Concorde Room (T5), Virgin Clubhouse (T3), and Amex Centurion (T3). Allow extra connection time between terminals — transfers require landside bus or train. Under UK261, delays of 3+ hours on departing LHR flights qualify for fixed cash compensation regardless of airline.

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.
