I've just booked QF/EK/EK/QF for LHR-DXB-BKK-DXB-LHR.
Outbound in J, Inbound in F. Means I experience J on the A380 of both airlines, and F on an EK 777 and F on a QF A380.
I won't see the shower function on the A380, and while that remains a random bucket list item, I'm looking forward to comparing and contrasting QR to EK properly...my only flight on EK was a QR misconnect.
Thanks to darthlemsip for alerting me to the fact that I could book to BKK!
