From TPG
JAL doesn’t impose fuel surcharges for Emirates bookings. Taxes and fees are capped at $78.20 for a round-trip award ticket.
Yes I see it now, interesting.. because on JAL they write half the RT cost but in reality its really the one way distance.
Also it says $78.20 to (DXB) UAE, doesnt say anything about MXP.. Its highly likely its around the same amount, just confirm once booked please
