Qantas customers travelling across its regional, domestic and international network are in for a bigger and better inflight and lounge dining experience as the airline rolls out a significant menu enhancement program this month.

The additional multi-million-dollar investment introduces new dishes and larger portions across all cabins, using high-quality ingredients from premium Australian producers.

It is the single biggest investment in Qantas inflight and lounge dining in a decade and comes as the airline returns to profit and accelerates its customer investment programs. These include a $100 million expansion of domestic and international lounges, progressive renewal of its aircraft and new routes.

The new menus have begun rolling out on domestic flights and will launch on international services from 29 March. Coinciding with autumn, they will feature seasonal ingredients with plant-based options across all cabins.
