UK to Australia would be a huge improvement and would mean I am significantly more likely to go there. I already happily fly 2-3 hours across Europe without it taking up an entire day of travel (30 minutes to the airport arrive 2 hours before, 2-3 on the plane and then 10 minutes from plane to taxi/train at the other end) vs the same + 20 hours of flying and likely a stop over.
