LHR · Heathrow is a four-terminal hub with official 2025 traffic of 84.5 million. CT scanners from 23 January 2026 let 2-litre liquids and laptops stay in the bag. Live Priority Pass is not No.1 in every terminal — T5 is Club Aspire, and T3 Plaza Premium on PP is arrivals only. There is no Chase Sapphire Lounge.
LTN · London’s fourth airport done right for LCCs: one clear terminal, CT screening that leaves bags packed (still ≤100 ml), two Priority Pass lounges, and a ~32-minute Express+DART hop from St Pancras — with morning peaks and drop-off fees as the main gotchas.
