As part of its sponsorship of the Sydney Gay and Lesbian Mardi Gras, Qantas changed its app to reflect rainbow colours. Customers can change the app design by going to settings on the app.
You may have to perform a forced reload ie deleting the app if you already have it and reinstalling it.
Qantas has been involved in the Mardi Gras since 2015. It has had a float in the parade and painted a rainbow flag onto one of its 737s. This would be in line with the CEO’s values. Mr Joyce is gay himself and has emerged as a role model. He was named the world’s most influential LGBT business executive in a 2017 annual listing published by the UK’s Financial Times.
