Frequently asked questions
- How long of a layover do I need?
- For domestic connections at the same airport, 45–60 minutes is typically sufficient. For international connections or connections requiring a terminal change, allow 90–120 minutes minimum.
- What happens if my layover is too short?
- If your flights are on the same booking, the airline is responsible for rebooking you if you miss the connection due to a delay. If booked separately, you bear the risk.
