Heathrow (LHR) is London’s main long-haul hub with four passenger terminals (2–5) linked by free transfers. Protected connections need honest buffers; Elizabeth line and Heathrow Express are the fastest city links. Plan lounges, Wi-Fi and left luggage by terminal — and check delay rights if your UK/EU itinerary breaks as of July 2026.

How is Heathrow laid out and which terminal should you use?
Heathrow runs four active passenger terminals: Terminals 2 and 3 sit in the central campus, Terminal 4 is south, and Terminal 5 is west for British Airways and Iberia. There is no Terminal 1 for passengers. Always follow your booking’s terminal code, not a memory of a previous trip.
This Heathrow guide covers terminals, transfer planning bands, city transport, lounges, Wi-Fi and left luggage for July 2026. Live flight boards and airline apps win when they disagree with any static guide.
Terminal 5 is the British Airways fortress; many Star Alliance carriers use Terminal 2; oneworld partners often cluster around Terminal 3; Terminal 4 hosts a mixed long-haul set. Re-check the terminal on your boarding pass the night before. See London and Gatwick when routing is still flexible.
| Terminal | Typical airline posture (planning) | Campus note |
|---|---|---|
| Terminal 2 | Many Star Alliance long-haul/short-haul | Central — walk/transfer to T3 <!-- VERIFY --> |
| Terminal 3 | Mixed long-haul / oneworld cluster | Central campus |
| Terminal 4 | Mixed long-haul / SkyTeam & others | South — allow transfer time <!-- VERIFY --> |
| Terminal 5 | British Airways / Iberia focus | West campus; own rail station |
| Inter-terminal | Free trains / buses / walkways | Follow purple signs; bags may need reclaim on self-transfers |
What connection time should you plan at Heathrow?
Treat published minimum connection times as legal floors, not comfort targets. Same-terminal protected tickets can work near the minimum on a calm day; terminal changes, UK Border Force peaks and self-transfers need much wider bands. Build buffer for bag reclaim if tickets are separate.
On a single ticket with through-checked bags, same-terminal international-to-international transfers are the calmest shape. Terminal 5 to Terminal 4 is a different day: free transit helps, but security re-clearance still eats the clock.
Self-transfers may need immigration, bag reclaim, re-check and security again — closer to a stopover than a connection. If the first flight is late on separate tickets, the second airline usually owes you nothing — see flight delay compensation rights. Prefer single tickets on flight deals.
| Transfer shape | Planning band (July 2026) | Why it matters |
|---|---|---|
| Same terminal, through-ticket | Often ~90–120+ min comfort | MCT can be tighter; peak queues bite <!-- VERIFY --> |
| T2 ↔ T3 through-ticket | Often ~2–2.5 hrs comfort | Short campus hop + security |
| T5 ↔ T2/T3/T4 through-ticket | Often ~2.5–3.5 hrs comfort | Rail/bus + re-clearance <!-- VERIFY --> |
| Self-transfer with bags | Often 4+ hrs preferred | Immigration + reclaim + re-check |
| Arriving late evening / departing early | Avoid tight turns | Fewer recovery flights |
What is the fastest way from Heathrow to central London?
Elizabeth line and Heathrow Express are the usual speed leaders into central London, with the Piccadilly line as the cheaper, slower Tube option. Coach and taxi/rideshare trade money for door-to-door ease. Pick by terminal, luggage count and whether you need Paddington, Bond Street or the City.
From Terminals 2 and 3 the Elizabeth line and Heathrow Express sit under the central campus; Terminals 4 and 5 have their own stations — follow rail signs.
Elizabeth line suits Bond Street, Farringdon or Canary Wharf without a Paddington change; Heathrow Express is built for Paddington speed; the Piccadilly line is slower and usually cheaper. Taxis help with heavy luggage, but M4/A4 traffic can erase the time advantage. UK travellers often compare parking and lounge extras before flying — see also London.
| Mode (LHR → central London) | Typical time band | Typical adult fare band | Best when |
|---|---|---|---|
| Elizabeth line | ~25–40 min to central stops | Often ~£11–£15+ contactless band | City / West End without Paddington change <!-- VERIFY --> |
| Heathrow Express | ~15–20 min to Paddington | Often ~£25–£40 advance/flexible | Paddington hotels; light luggage <!-- VERIFY --> |
| Piccadilly line (Tube) | ~45–60+ min | Often ~£5–£7 contactless band | Budget; Tube network hops <!-- VERIFY --> |
| National Express / coach | ~45–75+ min traffic-dependent | Often ~£6–£15 advance | Victoria / coach hubs |
| Taxi / rideshare | ~35–70+ min traffic-dependent | Often ~£45–£90+ meter/app | Door-to-door; late night; groups |
Which lounges can you use at Heathrow?
Heathrow lounges split into airline clubs, alliance partner access and pay-in walk-up or prepaid passes. British Airways Galleries and First spaces dominate Terminal 5; other terminals host Plaza Premium, No1 Lounges and carrier rooms. Eligibility depends on cabin, status, card benefits and day-pass rules — confirm before you walk.
Oneworld emerald/sapphire or BA Club World tickets usually point to Terminal 5; Star Alliance gold often points to Terminal 2. Pay-in lounges help on basic economy with hours to kill — prepaid beats walk-up when busy.
Priority Pass lists change; exclusion windows and guest rules still apply. Compare UK parking-plus-lounge extras before you leave home rather than at the kerb.
| Lounge type | Typical access path | Terminal note |
|---|---|---|
| BA Galleries / First | BA cabin / status / invite | Terminal 5 focus <!-- VERIFY --> |
| Star Alliance partner rooms | Star Gold / business tickets | Mostly Terminal 2 |
| Plaza Premium / pay-in | Prepaid or walk-up | Multiple terminals <!-- VERIFY --> |
| No1 Lounges / similar | Pay-in / some card programmes | Check terminal list |
| Airline contract lounges | Operating carrier ticket | Follow boarding-pass terminal |
Does Heathrow have free Wi-Fi and left-luggage storage?
Heathrow typically offers free Wi-Fi with a time or speed band after a splash-page login, plus paid faster packages on busy days. Left-luggage and luggage-wrapping desks operate in the main terminals with per-bag daily rates. Treat both as convenience tools, not long-term storage for valuables.
Connect to the official Heathrow network. Captive portals can drop during terminal changes — reconnect after you move campus.
Left-luggage helps on a long London day between flights. Photograph tags, note hours, and never store passports. For airline bag fees see British Airways policies.
| Service | Typical planning note (July 2026) | Tip |
|---|---|---|
| Free Wi-Fi | Splash login; time/speed band common | Use official SSID <!-- VERIFY --> |
| Paid Wi-Fi upgrade | Faster / longer sessions | Only if you need uploads |
| Left luggage | Per bag / per day desk rates | Check terminal hours <!-- VERIFY --> |
| Luggage wrap | Optional plastic wrap desks | Airlines may still open bags |
| Porter / assistance | Book via airline special assistance | Request ahead for connections |
What should you do if your Heathrow flight is delayed or cancelled?
Use the airline app first for rebooking, keep boarding passes and delay timestamps, and ask about care (meals, hotels) when rules require it. UK and EU frameworks can create compensation rights on qualifying flights after long arrival delays. Self-transfers and extraordinary circumstances weaken claims — document everything before you leave.
Start with the legal map in flight delay compensation rights, then file through your operating carrier with evidence. Heathrow disruption often cascades across terminals; a gate change can be a 20-minute walk, so refresh the board before you sit down in a lounge.
If you miss a separately ticketed onward flight, compensation and rebooking paths are weaker than on a protected through-ticket. Build buffers next time, or buy a single ticket when shopping on flight deals.
- Screenshot delay notices and new flight offers in the airline app
- Ask for care vouchers when overnighting is due under applicable rules
- Keep meal and hotel receipts with times stamped
- Note actual arrival time at the final destination for compensation thresholds
What is the practical bottom line for using Heathrow well?
Confirm your terminal the night before, build honest connection buffers, and pick Elizabeth line or Heathrow Express when time matters more than the cheapest Tube fare. Pre-book parking or lounges if you need them, travel with soft cabin bags, and keep delay evidence ready. Compare London airport routings before you buy.
Treat terminals as separate airports glued by free transit. Same-terminal BA itineraries feel calm; T5-to-T4 self-transfers feel like a second journey. Pair with Gatwick and London.
