What do I need to show as proof of purchase?

Whether it's the airline check-in counter, hotel reception or tour operator, please have your passport handy. They would especially like to see the passport of the lead traveller (who the reservation is under).

For domestic deals, a form of photo ID (such as your driver's licence) will suffice.

For peace of mind, you may like to have an electronic and paper copy of your booking confirmation at hand.
