True. On my existing DONE6 ex OSL purchased last November I was able to get a receipt for the whole trip from the AY site. I paid a total of just under $10k US. The base fare was NOK 74667 (about $7500 at that time) with taxes and fees of around $2500. Of that $2500 the receipt listed $1846 in YQ (fuel surcharges), with the remainder being composed of about 22 separate small ($7 to $96) charges for specific nation and security related taxes/fees. So the carrier imposed fees (YQ) are about 74% of the costs above the base fare. I remain curious how that $1846 gets divided among the various airlines involved.
