I wonder if CX is the only airline in OW which will somehow recognise other OW airline's Emerald on board (Not CX DM, I mean).
- Greet by ISM
- Offer of a bottle of so called DM water (Not always)
- Bring asked of meal choice first.

But being a CX DM, received no similar level of recognition on other OW airlines I travelled (IB, BA, AA, QR, JL...)

Any experience?
