We've got the tickets for the UK! Went into Flight Centre and paid the whole thing. We're flying out of Sydney on the 12th of March, and arriving in London on the morning of the 13th. We're flying Etihad, which only recently started flying to Sydney. We'll be going to London via Abu Dhabi, giving a chance to break up the flight and look around the (apparently) very fancy new airport there.
The tickets came upto $2000 each.. so that's the first big expense of the trip. Now we need to start filling out all the other forms.. plan to have the visa forms filled tonight and lodged by early next week.
