Know the Airport Connection
Heathrow publishes separate guides for Terminals 2, 3, 4 and 5; Terminal 2 is also called the Queen's Terminal. The terminal number is an essential part of the destination rather than an optional detail after the airport name.
Choose the Actual Road Journey
Heathrow's current transport guidance distinguishes passenger collection from terminal drop-off and gives different collection arrangements for Terminal 4. Ask the cab operator to confirm the current terminal-specific meeting instructions. Do not carry an old forecourt meeting assumption into a new booking.
Flight Details, Luggage and Readiness
For a Heathrow Airport taxi or minicab enquiry, provide the flight number, date and London-time details as well as the airport destination. Explain the party size and luggage before asking the operator to confirm the vehicle. For an arrival, landing, reclaiming bags and being ready to meet are different moments; agree how readiness and any waiting will be handled.
For departure, follow the airline's check-in requirements and discuss the proposed pickup with the cab operator. Ask for the complete proposed price and airport meeting instructions before accepting a booking.
