Yes not very palatable. Just under twice the price compared to Oman Air who can be booked from around $8,700 for two. But of course that does not include the cost of getting to Asia. I have seen prices around $15,000 for two via Mauritius but that is still a lot less than many other airlines. For example Finnair, using QF out of Perth, starts from $20,000 in September. SQ is from $23,500 up and QR begins at $22,000. CX seems to be possible for around $15,000 as well but with 15 hour plus stopovers and only 3 flights a week. I am very doubtful about using them at the moment.
I am hoping, probably vainly, for reasonable prices to appear otherwise this trip may never happen.
