Even if the DRW/SIN flight was catered FOC management is short sighted if they think it's just about food, or lack of.
Other factors that annoy passengers re JQI DRW/SIN is:
a) Misrepresentation of product - they think QF355 means they are travelling Qantas not on JQ57.
b) No frequent flyer points - "but it's a Qantas flight number".
c) No through checking of baggage to certain airlines outside the One World carriers.
d) They cannot check you in to a connecting QF flight eg QF5 SIN/FRA even if your bags are checked through. The JQ Navitaire system does not interface with the Qantas Departure Control System for the purpose of passport & immigration info. As a result the pax have to queue up for hours in SIN for their onward boarding pass when it used to be so easy to get all the boarding passes at the first departure point when DRW/SIN was operated by Qantas. This applies in reverse so you can imagine how well this goes downafter a long flight from Europe to Singapore.
When management 'brainstorm' these ideas they should ask themselves if they would want to fly Jetstar. We all know the answer to that one, so why on earth to they think it's acceptable to the general public if it's something they wouldn't do themselves???
