Hi all, I have booked my first DONE3 and very much looking forward to the experience. My route is as follows:

OSL-doh-hel-nrt-BLR-nrt-SIN-hnd-dfw-bos-lax-anc-DFW-sea-lax-doh-OSL

(Apologies if I've got the presentation wrong; my stopovers are in BLR, SIN and DFW).

Can anyone give me any guidance on the taxes I've paid - c.£1,500. Reading through this thread and the User Guide, have I incurred additional taxes from having a stopover in BLR? Almost all of the flights are codeshares on AY and JL (OSL-DOH and LAX-DOH on QR; ANC-DFW on QF). Any feedback gratefully received - would they be lower if I went ex-TYO? Thinking ahead to my next booking. Thank you!
