Good morning both,
I have just double and triple 🙂 checked with our aviation department.
From April, we will be flying with to British Airways so we can still go via Singapore.
From January 2014 we will switch back to Qantas and go via Dubai.
It's an airlines prerogative to make as many changes as they see fit, we try and keep consistent schedule/timings/route so that's why we are switching between the two.
I hope this helps and we see you on a tour soon Dave,
Kindest,
Ben
