    Heathrow Airport FAQ

    A £6 charge applies to every vehicle entering the terminal drop-off zones. You cannot pay this at a machine or barrier at the airport. You must pay online or via the automated telephone service (0330 008 5600) by midnight the day after your visit. Failure to pay on time will result in an £80 Penalty Charge Notice (PCN). Regular visitors can set up “AutoPay” to automatically deduct the fee and avoid fines.

    From the 1st of January 2026, the drop-off charge will increase from £6 to £7. Additionally, a maximum stay of 10 minutes will be introduced to the drop-off areas.

    Yes. You can drop passengers off at the Long Stay Car Parks for free (up to 30 minutes). Passengers can then take a free shuttle bus to the terminal doors, which runs every 10–15 minutes.

    Rules currently differ by terminal due to the rollout of Next Generation Security Checkpoints.

    • Terminals 2, 3, and 5: These terminals have largely upgraded to CT scanners, allowing liquids up to 2 litres to remain in your bag, along with laptops and electronics.
    • Terminal 4: This terminal may still operate older lanes where the strict 100ml limit applies. Liquids must be in containers of 100ml or less and fit in a single transparent, resealable bag.

    Yes, Heathrow offers free, unlimited Wi-Fi. Select the network _Heathrow Wi-Fi and follow the on-screen registration instructions. It is accredited as “Friendly Wi-Fi,” meaning it filters inappropriate content.

    If you remain “airside” (do not pass border control) and have a connecting flight on the same ticket, you generally do not need a full visitor visa, though you may need a Direct Airside Transit Visa depending on your nationality. However, starting in late 2025/early 2026, the UK is rolling out the Electronic Travel Authorisation (ETA). While passengers transiting airside are currently temporarily exempt, this rule is subject to change, and you should check the official gov.uk site before travelling.

    • Airside (Connecting Flights): Follow the purple “Flight Connections” signs to take free dedicated buses between terminals. You do not need to collect your bags if they are checked through.
    • Landside (Separate Tickets): You can use the Heathrow Express and Elizabeth Line trains for free to travel between terminals (e.g., from Heathrow Central T2/3 to Terminal 4 or 5). You must get a free “Inter-terminal transfer” ticket from the machines or use a contactless card (you won’t be charged if you stay within the airport zone).

    • On the Aircraft: Contact your airline directly; they manage items left on their planes.
    • In the Terminal/Security: Heathrow’s lost property is managed by Smarte Carte. You must search their online database (LHR Lost & Found) to log a claim. Do not call the general airport switchboard as they cannot access the lost property vault.

    Yes, security fast track is available for £12.50, you can pre-book book online. If you’re a frequent flyer, have purchased a premium ticket with your airline, fast track may be included with your ticket.

    Qsensor FAQ

    Live data: For the majority of the airports we track we use live data from the airport. For the remaining airports we provide an estimate, and we communicate that it’s a best-guess only.

    Search: By airport name, IATA code, city, county, country or region. To save you time, we keep your last visited airports on the front page. If you can’t find an airport, contact us using the contact form and we will look to add it. 

    Current average wait time: The airport’s latest average security, passport control or customs queue wait time. If the airport has multiple queues, we display the average of them. If you want a more granular view that includes wait times for individual queues, take a look at the terminal level wait times. We regularly update each airport’s data,  but make sure you click the “i” icon to check when the last update was made.

    Terminal level wait times: The latest security or customs queue wait time for individual terminals. Click on the terminal to access more information at the terminal level. Please note that this data is not available for all airports. We are working to expand this functionality to as many airports as possible.

    Historical wait times: The typical wait time on different days and times over the past 2 weeks. Click the filter at the top right of the graph to cycle through the days of the week.

    Add a security or customs queue wait time: How was your airport security experience? Contribute to the community by inputting your wait time. This feature is only available for airports where Qsensor does not automatically track data. To add a wait time, simply click the “Add Your Time” button on the airports page and follow the instructions.

    Please note that this data is monitored and may be modified or deleted if found to be invalid.

    Click the “i” icon to view and take note of more contextual information on each airport. “Airport Last Updated” denotes the last time the data was refreshed.

    Our sources for wait time data vary and may include air travel data aggregators, federal agencies such as the TSA, CATSA CBP, or information from the airport and its affiliated service providers. For airports Qsensor does not track automatically, we source data from passengers that have inputted their wait time using the “Add Wait Time” button.

    Qsensor is not affiliated with any airport, airline, or associated service provider.

    We regularly check queue times and flight delays for accuracy, however all times are estimates and waiting times and delays may not accurately reflect your experience. It is advisable to arrive at the airport well in advance and follow the recommendations of the airlines and airports.

    There are a wide array of ways that queue data is measured. Including but not limited to looking at how long a passenger takes to get from scanning their boarding pass to exiting the security or customs area. Auditing passengers on how long it took them to pass through security or customs as well as Qsensors’ proprietary system for user added wait times. 

    For airport wait times, we currently support over 110 airports worldwide. Whether it be London Heathrow, Istanbul, or Miami – we have got you covered. More are added all the time. Is Qsensor missing an airport that you want to be supported? We are more than happy to accommodate your request, get in touch via the contact form.

    For airports Qsensor automatically tracks, this message may also be shown if we haven’t recently gotten data from the airport. This typically rectifies itself within 12 hours.
