That depends on several key factors, but here’s a general guide:
Minimum Recommended Times
- Same Terminal (e.g., both flights in Z or B): 60 minutes is the absolute minimum, but it’s tight and stressful. You must move quickly.
- Different Terminals (e.g., Z to B or A to B): 90 to 120 minutes is strongly recommended. This involves taking the SkyLine train (airside) or a bus.
- Terminal 1 to Terminal 2 (or vice versa): At least 2 hours (120 minutes). This often requires exiting security, taking the Terminal Shuttle Bus or train (landside), and re-clearing security. It’s a longer process.
Critical Factors That Affect Your Time
-
Your Ticket Type:
- Single Ticket: If both flights are on one ticket (e.g., booked together through one airline), the airline is responsible for getting you to your destination. They will only offer connections they consider legal (usually 45-75 min minimum). If you miss it due to a delay, they will rebook you.
- Separate Tickets: If you booked the flights separately, you are responsible for the connection. You must collect your bags, check in again, and clear security. For this, 3+ hours is a much safer bet, especially if you need to go between terminals.
