Your booking is reserved for 10 minutes while you complete the checkout process. This reservation period helps prevent overselling, while still giving you enough time to complete your booking.
If your booking is not completed within 10 minutes, the reservation will expire and will be released back into general sale. If you still intend to make a booking, you will need to add the booking to your basket again.
During periods of high demand, this process may cause ticket availability to fluctuate as reservations are made, expire, and tickets are returned to sale.
