Another great option this time using Avios is within Australia. Qantas fly their A330s on a daily basis between Sydney and Melbourne. It’s important to check you’re on the correct plane as this route is usually operated by a 737 which is pretty standard. This can be booked using as few as 5,000 BA Avios and fees.
While it’s not long in the sky it’s a great way to travel between these two must visit cities. The lounge in Sydney is also great as it has a great selection of wines along with a toasted sandwich maker which was a great novelty. So arrive early, the evening I flew this route the food ran out onboard so maybe sit towards the front if you want the full experience.
