๐ข Terminal Information
London Heathrow has four active terminals (T2โT5). T2 and T3 sit in the central terminal area and are linked by an airside/landside pedestrian corridor in 10โ15 minutes, while T4 and T5 sit on separate spurs and rely on free Flight Connections buses or the inter-terminal Heathrow Express shuttles (every 15 minutes) for 10โ20 minute transfers. All terminals feed into the central rail/tube station complex, with T5 using its own station for both the Elizabeth line/Heathrow Express and the Piccadilly line. Clear terminal signage, colour-coded zones and multiple lifts/escalators make wayfinding straightforward.
Security checkpoints sit on Departures in every terminal (multiple lanes in T2, a central hall in T3, a large central checkpoint in T5, and T4โs main hall). Fast Track is available for eligible premium and status passengers. Typical waits run 10โ20 minutes off-peak and 20โ35 minutes during the morning/evening banks; expect additional time if transferring landside between terminals because re-screening is mandatory.
UK Border Force operates large immigration halls with eGates in T2โT5; Fast Track immigration is offered for premium cabins and select statuses. International-to-international Flight Connections centres in each terminal allow eligible airside transfers with dedicated security, while passengers changing terminals often ride an airside bus before clearing a smaller re-check screening point. Customs exits (green/red channels) sit immediately after baggage reclaim in each arrivals hall.
Amenities vary by terminal: T2 hosts Plaza Premium and United/AC/UA Star Alliance lounges plus Heston Blumenthalโs The Perfectionistsโ Cafรฉ and a large duty-free. T3 concentrates many oneworld and Virgin Atlantic Clubhouse lounges alongside Cathay Pacific, Qantas and American lounges, plus dining such as Oriel and Pret. T4 features the Plaza Premium lounge, Etihad and Qatar lounges, and a quieter mix of cafรฉs/shops. T5, the British Airways hub, offers multiple BA Galleries/First lounges, an Aspire lounge, Gordon Ramsay Plane Food, and extensive retail including World Duty Free, Prada and Harrods.
Accessibility is step-free across terminals with ramps, elevators, tactile paving, induction loops and Changing Places facilities in T2, T3 and T5. Special assistance reception points sit kerbside and inside departures; pre-booking is recommended. Families can use โStay & Playโ soft play areas in T2 and T5, baby-change rooms in every washroom cluster, and family security lanes during peak school-holiday periods.
๐ Connection Tips
LHR requires re-security screening for terminal transfers. Allow extra time for immigration during peak hours. Heathrow Express is the fastest inter-terminal transport.

๐ข Terminal Information
Leuchars Station Airfield (ADX), with ICAO code EGQL, located in Leuchars, Fife, on the east coast of Scotland, is primarily a British Army installation, known as Leuchars Station. It serves military operations, including acting as a diversion airfield for military aircraft from RAF Lossiemouth. While the airfield is fully operational 24 hours a day, 365 days a year, it does not operate as a public commercial passenger airport.
As a military airfield, Leuchars does not have typical civilian terminal facilities. Any terminal areas are rudimentary and are not designed for general public access. Passenger amenities are extremely limited, with accommodation available only for service personnel. The layout is highly controlled and security-focused, with operations geared towards efficient, secure movements for authorized military personnel, VIPs, or specific charters.
Security procedures at ADX are exceptionally stringent, reflecting its critical military role. All personnel and baggage undergo thorough screening protocols that are far more extensive than typical commercial airport procedures. Access to the base and any terminal area is highly restricted, requiring proper authorization and identification. For any international flights (which are highly specialized and not public commercial), immigration and customs facilities would be handled discreetly and efficiently for authorized personnel within the secure environment of the base. There are no public immigration or customs services in the traditional commercial sense.
๐ Connection Tips
Leuchars Station Airfield (ADX), formerly RAF Leuchars, is an active British Army installation and RAF unit that does not host regularly scheduled commercial passenger flights. Consequently, the traditional concept of 'connecting' between airlines does not apply here for the general public. For authorized civilian flights, the airfield operates under a strict Prior Permission Required (PPR) mandate. Pilots must submit a PPR application at least seven business days in advance, providing a full schedule, accurate crew and passenger manifests, and proof of insurance. Changes to the manifest must be revised immediately to avoid significant security delays upon arrival. Additionally, a fee covering Crown Indemnity is required for all civilian operations at this military facility.\n\nAircraft usage is subject to specific weight limits, with private aircraft capped at 45.5 metric tons and charter flights at 10 tons. Routine flying hours are generally restricted to Monday through Friday, 09:00 to 17:00, and any activity outside these windows requires special advance approval from base command. Once on the ground, passengers must be met by pre-arranged transport, as there are no on-demand taxi ranks or ride-sharing services stationed within the secure perimeter of the base. It is essential to have valid government-issued identification or a passport ready for inspection at the main gate.\n\nFor those needing to connect to the wider UK transport network, the Leuchars railway station is located just outside the base in Leuchars village, a short taxi ride or a moderate walk from the main gate. This station is a major stop on the East Coast Main Line, providing frequent and direct rail connections to Dundee (10 minutes), Edinburgh (60 minutes), and Aberdeen. For scheduled commercial air travel, visitors typically use Edinburgh Airport (EDI) or Glasgow Airport (GLA), which are reachable via rail or a roughly 60-90 minute road transfer from Fife.
