Heathrow Tightens US Flight Connections: What Travellers Need to Know
Heathrow’s stricter US flight connections: Key changes

Travellers flying from London Heathrow to the United States now face stricter connection times due to enhanced security checks. The changes, introduced to streamline border control processes, mean passengers must allow extra time for transfers—especially when switching terminals.

Why the Change?

Heathrow has adjusted its minimum connection times (MCT) for US-bound flights following updated security protocols. These measures, designed to align with US Customs and Border Protection (CBP) requirements, include additional document checks and baggage screening.

Key Impacts:

  • Terminal transfers: Passengers connecting from Terminal 3 to Terminal 5 now need at least 90 minutes (up from 60).
  • Same-terminal connections: A minimum of 60 minutes is required for flights within Terminal 5.
  • Missed flights: Airlines may not rebook passengers who fail to meet the new deadlines.

Tips for Smooth Travel

  1. Check your itinerary: Confirm connection times when booking.
  2. Arrive early: Allow extra time for security and document checks.
  3. Use fast-track services: Consider premium security options if available.

Heathrow advises travellers to consult their airline for specific guidance, as policies vary by carrier. With summer travel peaks approaching, planning ahead is essential to avoid disruptions.
