You`ll have more choice if you go from LHR. If you`re stopping over, SIN or somewhere in the Far East will be a lot more interesting than Dubai. It`s eons since I did LHR-SIN-PER but I think that`s a good way to go. Once you get to SIN, you`ve broken the back of the journey. It`s a relatively short hop from there to PER.
Are you stopping overnight en route? It can be worth going to a decent travel agent to see what they can do. Airlines work on the premise that the first port of call for passengers is their website so that will be the most expensive. The airlines sell tickets to travel agents at a discount and the travel agent can pass that on to the passenger. They usually have to sell you something else to qualify being able to sell the ticket at that rate (ie a night`s hotel accommodation or some car hire) It might be worth checking that out but don`t leave it to long as the price will go up considerable, the closer you get to departure.
We wont need night stop over as we hope to get there as fast as we can. lol.
My heads whirling as there are so many suggestions.
My Niece In Perth is enquiring too and she has come up with £850 with Emirates flights. (1,300 dollars)
Wont sleep tonight as my minds going round in circles. Cheers again Abers x
